Introduction

Underpinning the American Dream is the idea that hard work pays off.Americans embrace the promise that over time a conscientious workeffort will yield higher pay and status, greater time for leisure, andprotection from poverty. However, for many working Americans employ-ment is not a sufficient condition for keeping them from poverty’s grasp.Indeed, over the last quarter century, dramatic changes in the economic

landscape faced by American workers have served to put the issue ofworking poverty on center stage in the national poverty debate. Evenwith the good fortune of a “full-employment” economy in the latter1990s, many American workers and their families remained poor atdecade’s end (Bernstein 2004). The salience of this issue is highlightedby the recent popular success of such books as Nickel and Dimed: On (Not)Getting By in America (Ehrenreich 2001), The Betrayal of Work: How Low-Wage Jobs Fail 30 Million Americans and Their Families (Shulman 2003), andThe Working Poor: Invisible in America (Shipler 2004), all of which werepublished after the much heralded expansion of the 1990s.

Working poverty has been defined in a variety of ways (see Blank andLondon 1995; Kasarda 1995; Klein and Rones 1989; Lichter, Johnston,and McLaughlin 1994; Morrissey 1991; Mosisa 2003), but conceptuallyhinges on whether individuals attached to the labor market throughformal employment fail to earn an income that keeps them out ofpoverty. Working poverty has long been an important part of the povertyproblem in the United States, and historically this has been especiallytrue in rural America (Brown and Hirschl 1995; Jensen, McLaughlin,and Slack 2003; Lichter et al. 1994; Lichter and McLaughlin 1995; RuralSociological Society Task Force on Persistent Rural Poverty 1993).However, the increasing national attention garnered by the issue sug-gests that working poverty may be affecting growing numbers across therural-urban continuum. In this article I examine the issue of workingpoverty by drawing on data spanning the years 1979 through 2003, witha special comparative focus on the situation in metropolitan (metro)and nonmetropolitan (nonmetro) areas. In doing so, I seek to outlinehow the contours of working poverty have changed across the metro-nonmetro divide over the last quarter century. Further, I seek to assesshow family labor supply and period effects, net of other importantsociodemographic variables, have influenced the likelihood that workersand their families will be poor.

Theoretical Considerations

An important recent development in stratification research has been aconcerted call for the consideration of geographic space as a key axis ofsocial inequality (Gans 2002; Lobao 2004; Lobao, Hooks, and Tickamyer2007; Lobao and Saenz 2002; Tickamyer 2000). Lobao et al. (2007)outline four overarching ways in which space can be brought into socio-logical research on inequality. First, space intersects with class, gender,race/ethnicity, and other statuses in important ways. This is true both interms of the spatial distribution of population groups—such as the

changing spatial concentration of the rural poor (Lichter and Johnson2007)—as well as in how those of different social statuses use and expe-rience space—for instance, the negotiation of long commutes for low-wage rural workers (Webb 2003) or the locational embeddedness offamily livelihood strategies (Nelson and Smith 1999; Ziebarth and Tigges2003). Second, space can serve to channel inequality processes by eithermuting or amplifying their effects. For example, research has shown thereturns to work (Lichter et al. 1994) and human-capital investment(McLaughlin and Perman 1991) tend to be lower in rural areas thanurban areas. Third, social inequality is space forming. An illustration ofthis effect is the regional concentrations of high and persistent povertyin places such as Appalachia, the Mississippi Delta, and the TexasBorderland (Lyson and Falk 1993; Rural Sociological Society Task Forceon Persistent Rural Poverty 1993; Slack et al. 2009), geographies ofdisadvantage that are the products of social struggle and negotiation.Last, spatial processes and inequality processes can be causally meshed.For example, economic restructuring (Falk, Schulman, and Tickamyer2003) and devolution in the form of welfare reform (Tickamyer et al.2007; Weber, Duncan, and Whitener 2002) are inherently spatialprocesses.

Scholars concerned with spatial inequality have also called for explicitattention to issues of comparative advantage and disadvantage acrossspace as well as to issues of spatial scale. While an understanding of thesources of comparative advantage and disadvantage are central to under-standing questions of social inequality, Tickamyer (2000) argues thatspatial context is often overlooked as a setting for and component ofstratification. Relational spatial constructs such as metro and nonmetroallow for the comparison of different types of locations and the social-spatial structures characterizing them (e.g., households, labor markets,human-capital and population factors) that speak to “configurations ofsocial, political, demographic, and economic practices that providepeople and places with varying degrees of power, opportunity, andadvantage” (Tickamyer 2000: 810). Those calling for attention to spatialscale have noted that stratification research has tended to focus oncross-national, national, and urban scales but has left the subnationalscale—spatial units between the level of the city and nation–state—relatively neglected in accounts of inequality (Lobao 2004; Lobaoand Hooks 2007; Tickamyer 2000).

Lobao (2004) has argued that attention to these issues stands tosimultaneously strengthen rural sociology and demonstrate why theapproach taken by rural sociologists is critical to the social sciences. Inthis view, the topic of spatial inequality strengthens rural sociology by

helping tie together substantive strands in the field, introducing newconceptual perspectives and methodologies, and by speaking to ques-tions of uneven development by drawing out how territorial inequality iscreated, perpetuated, and changed. At the same time, rural sociology’stradition of comparative regional analysis and attention to middle-rangeterritorial units puts the discipline in a position to play a prominent rolein advancing the social-scientific understanding of spatial inequality. Forexample, while social scientists have disproportionately focused on largecities to understand development processes, rural sociologists stand toprovide a needed corrective by bringing the experiences of other spacesand places to bear. Further, attention to these concerns has the potentialto speak to broader questions about the national spatial division of laborand the territorial expression of new forms of inequality.

This study draws on these considerations by examining the relation-ship between work and poverty with an explicit comparative focus ondifferences between metro and nonmetro areas. More specifically, thisresearch contributes to the body of scholarship that draws attention toissues of comparative advantage and disadvantage across space as well asthe consideration of the subnational scale. This research also speaks toquestions of how space intersects with other social statuses (e.g., povertyand the characteristics of workers and their families) and how spaceserves to channel inequality processes (e.g., differential returns to workand human capital), and more indirectly to the meshed nature of spatialprocesses and inequality processes (e.g., economic restructuring anddevolution). Moreover, this study joins space with its counterpart time byexploring how this relationship has changed over the last quartercentury.

Background

Change in the National Context

In the period spanning from the end of World War II to the mid-1970s,the average standard of living in the United States improveddramatically—median income rose, inequality declined, and poverty fell(Harrison and Bluestone 1988; Massey 2007; Morris and Western 1999).But after the mid-1970s the context changed markedly in what has beenvariedly referred to as the “Great U-Turn” (Harrison and Bluestone1988) and the “Fall of Egalitarian Capitalism” (Massey 2007). Inequalitybegan a steady upward march as the incomes of those at the top of thedistribution increased dramatically, median income crept upward onlyslightly, and the incomes of those at the bottom of the distributionstagnated (Harrison and Bluestone 1988; Massey 2007; Morris and

Western 1999). Poverty rose in the late 1970s and remained highthroughout the 1980s and early 1990s. It then fell during the latter1990s, only to rise again at the start of the twenty-first century (DeNavas-Walt, Proctor, and Smith 2008).

This period has been characterized by both macroeconomic growthand decline. Since 1980, the macroeconomy has gone through thelongest contraction (1981–1982, 16 months),1 and the longest (1991–2001, 120 months) and third longest expansions (1982–1990, 92months) in the postwar era (National Bureau of Economic Research2009). Research has shown a clear countercyclical relationship betweenthe state of the macroeconomy and poverty (e.g., Gunderson and Ziliak2004; Iceland 2003)—when the economy is strong, poverty tends todecrease; and when it is weak, poverty rises. In the 1980s, the gains ofeconomic growth were largely offset by rising inequality and the increas-ing share of families headed by single females, serving to keep povertyhigh throughout the decade. But in the 1990s, the effect of inequalitywaned, the shift toward vulnerable family structures slowed, and theeconomy enjoyed an unprecedented expansion. Together these trendscombined to decrease poverty during the latter half of the decade(Iceland 2003).

American labor supply and demand have also been in flux during thistime. On the supply side, American families have steadily increased theirlabor supply to keep pace with the modern economy. Labor-force par-ticipation among women increased substantially during the 1980s, atrend that continued in the 1990s albeit at a slower pace. Much of thisoverall increase was driven by a rise in the formal labor supply of marriedwomen (Juhn and Potter 2006). By 2000, nearly two-thirds of marriedcouples with children were characterized by the employment of bothspouses (Bureau of Labor Statistics 2002). The rise in dual-income fami-lies is related to the decline in real earnings among male workers sincethe early 1970s, a trend that has necessitated families increasing theirlabor supply in order to maintain their standard of living (Danziger andGottschalk 1995).

On the demand side, the globalization of world markets, facilitated byrevolutionary technological advances in computerization, has led tomajor changes in the structure of the labor market confronted byAmerican workers (Massey 2007; Rifkin 2004). Beginning in the 1970s,U.S. firms began to restructure in response to growing internationalcompetition. Two key trends characterized this restructuring: (1) the

shift from a goods-producing to a service-based economy; and (2) therise in nonstandard employment—outsourcing, subcontracting, andtemporary, contingent, and part-time work contracts (Morris andWestern 1999). Following World War II, manufacturing represented thelargest sector of employment, but it was surpassed by the service sector inthe early 1980s (Meisenheimer 1998). In fact, during the 1990s theservice sector accounted for more than 97 percent of all job growth(Goodman and Steadman 2002). While the service sector comprises awide range of jobs that vary greatly in quality, the evidence indicates ashift toward labor-market bifurcation due to displacement of manufac-turing workers and the divergence of job quality within the service sector(Harrison and Bluestone 1988; Meisenheimer 1998). This process hashad particularly painful consequences for men with a high school edu-cation or less (Bianchi 1995; Morris and Western 1999).

The rise in nonstandard employment has been driven by desires onthe part of both employers and employees for greater flexibility. Inresponse to increasing global competition and volatile consumerdemand, firms have used outsourcing and contingent work contracts toreduce labor costs and shift a greater share of the risk of market uncer-tainties onto workers. Some workers have benefited from these arrange-ments, though most nonstandard workers indicate they would preferstandard employment if given the choice (Kalleberg et al. 1997). Onbalance, nonstandard employment has been shown to strongly increasethe likelihood that workers will face low earnings and lack benefits(Kalleberg, Reskin, and Hudson 2000).

The 1980s and 1990s also saw a major shift in the emphasis of nationalpoverty policy, evolving from the ambitious agenda of the 1960s, whichsought the abolition of poverty, to one centered on concerns aboutwelfare dependency, nonwork, and unwed motherhood (Ellwood 1989;Mead 1992; Murray 1984). In 1996, the U.S. Congress passed thePersonal Responsibility and Work Opportunity Reconciliation Act(PRWORA), the central premise of which was that the welfare systemfostered dependency and that the best way to reduce poverty andencourage self-sufficiency was to move people from “welfare to work.”PRWORA ended the nation’s largest federal cash-assistanceprogram—Aid to Families with Dependent Children—as an entitlementand replaced it with Temporary Assistance for Needy Families, a stateblock-grant program with time limits on receipt and the requirement of“work effort” in exchange for aid. In the wake of this legislation caseloadsfell to less than half their previous level nationwide and the low-wagelabor market experienced a massive influx of former welfare recipients(Lichter and Jayakody 2002).

Other important policy considerations for those working on the eco-nomic margins include the declining real value of the minimum wageand expansions of the Earned Income Tax Credit (EITC). Between 1980and 1990, Congress failed to raise the minimum wage a single time,resulting in a 30 percent drop in its real dollar value, the largest andlongest continuous decline in the postwar era (Card and Krueger 1995).At the same time the nation witnessed significant federal and stateexpansions of the EITC, which has been credited with having substantialimpacts on after-tax poverty in the 1990s (Gunderson and Ziliak 2004).

Metro and Nonmetro Areas in Comparative Perspective

The context outlined above culminates in important questions about theability of many American families to make ends meet. This issue may bea particular concern for those living in nonmetro areas, where work hastraditionally offered less protection from poverty (Brown and Hirschl1995; Jensen et al. 2003; Lichter and McLaughlin 1995; Rural Sociologi-cal Society Task Force on Persistent Rural Poverty 1993), a comparativedisadvantage that increased dramatically during the 1980s (Lichter et al.1994). Evidence suggests that the unprecedented economic expansionof the 1990s, as measured by unemployment or wage growth, was lessbeneficial in reducing absolute poverty rates in nonmetro areas(Gunderson 2006). Even with the boom of the latter 1990s, low wagescontinued to plague many rural workers at decade’s end. By 1999, morethan a quarter of nonmetro workers over age 25 continued to earn wagesthat—if earned full-time, full-year—would still leave them below thepoverty threshold for a family of four (Bowers, Cook, and Gibbs 2000).

Research has shown that in comparison to those in metro areas,nonmetro workers face a higher likelihood of being underemployed(Slack and Jensen 2002, 2008a), and once underemployed are less likelythan their metro counterparts to regain adequate employment (Jensenet al. 1999). The problem of marginal employment is underscored bythe fact that the nonmetro poor tend to rely more heavily on incomegenerated from work and less on public-assistance programs than dotheir metro counterparts (Jensen and Eggebeen 1994; Lichter andJensen 2002).

The disadvantages borne by nonmetro workers are rooted in bothcompositional and structural differences between metro and nonmetroareas. Compositional factors, such as lower average educational levels innonmetro areas (Beaulieu and Mulkey 1995), contribute to higher levelsof inadequate employment. At the same time, research has shown thatjobs in nonmetro areas tend to pay lower wages for comparable work and

provide lower returns to the human-capital endowments possessed byworkers (McLaughlin and Perman 1991). Structural factors, such asphysical isolation and lack of economic diversification, serve to limit theemployment options and opportunities of nonmetro workers.Because rural areas tend to rely on less diverse local economies, theimpact of economic restructuring has often proven particularly unkind(McLaughlin 2002). Data from the mid-1990s indicate that althoughnonmetro workers were less likely to be displaced than metro workers,they had a lower probability of finding new employment after losingtheir jobs (Hamrick 2001). Recent research has also shown that non-metro workers are more likely than their metro counterparts to beemployed in nonstandard and varied-hour work—jobs which, onaverage, provide lower wages and fewer benefits (McLaughlin andColeman-Jensen 2008). And workers hailing from economically margin-alized groups—such as racial and ethnic minorities (Slack and Jensen2002; Summers 1991) and single-female-headed households (Brown andLichter 2004; Snyder and McLaughlin 2004)—have been shown to faceparticular disadvantages in nonmetro areas.

Current Study

Growing recognition of the theoretical relevance of spatial inequality,changes in the economic context faced by American workers over recentdecades, and the particular historical disadvantages faced by ruralworkers raise important questions about the economic well-being ofworking families and comparative advantages/disadvantages in thisregard across the metro-nonmetro divide. In what follows I draw on datafrom 1979 through 2003 to assess how the relationship between workand poverty has changed over the last quarter century. Throughout, Ipay special attention to the comparison of working poverty betweenmetro and nonmetro areas.

Data and Methods

To address these objectives, I analyze data drawn from the MarchCurrent Population Survey (CPS) in three-year intervals from 1980through 2004 (i.e., 1980, 1983 . . . 2004). Collected by the Bureau of theCensus on behalf of the Bureau of Labor Statistics, the CPS is a nationallyrepresentative monthly survey of the civilian, noninstitutionalized popu-lation, and is the principal source of official labor-force data. The Marchsurvey (or Annual Social and Economic Supplement, formerly theAnnual Demographic Survey) contains a variety of data not collected

370 Rural Sociology, Vol. 75, No. 3, September 2010

during other months of the year. These data allow researchers todescribe the socioeconomic and demographic characteristics of indi-viduals, families, and households in much greater detail. While I use thesurvey data in three-year intervals from 1980 through 2004, the incomeand employment data I draw on actually reference the preceding year(i.e., 1979 is the reference for the 1980 survey, 1982 is the reference forthe 1983 survey, and so on). Because poverty, labor supply, and periodeffects are of central interest in this analysis, it is the reference year (i.e.,1979, 1982 . . . 2003) that I refer to in describing the results. The ninedata files were concatenated and analyzed as a single dataset.

Measuring Working Poverty

The official poverty measure in the United States is based on an approachdeveloped in the early 1960s and has been subject to only minor modifi-cations since that time (see U.S. Bureau of the Census 2008). The measureuses a set of income thresholds that vary by family size and composition.Families are defined as all individuals related by blood, marriage, oradoption who reside in a given household. Family income is calculated asthe sum of before-tax money brought into a household by all relatedmembers in the form of earnings or cash transfers (e.g., Social Security,public assistance, and unemployment compensation). The value ofnoncash transfers (e.g., food stamps, health care, and housing subsidies)and capital gains and losses are not considered. The thresholds wereoriginally formulated to represent the cost of a minimally acceptable dietmultiplied by three to allow for expenditures on other goods and services,and have since been pegged to inflation to adjust for increases in the costof living. In the CPS, poverty thresholds are based on a family’s annualincome in the year preceding the March interview (e.g., the March 2004survey asks about various sources of income in 2003). If a given family’sincome falls below its specified threshold, then that family (and everyindividual in it) is defined as poor.

Whether the official poverty measure provides a realistic standard ofwhat constitutes a minimally adequate standard of living has been thesubject of much contentious debate (see Citro and Michael 1995;Ruggles 1990). One important criticism of the official measure, espe-cially in assessing metro-nonmetro differences, is that it fails to adjust forgeographic differences in the cost of living. However, the degree towhich this problem misrepresents metro-nonmetro differences in eco-nomic well-being is difficult to determine. Housing costs are generallylower in nonmetro areas, but other costs of living, such as transportation,food, and health care tend to be higher (Nord 2000). While experts

continue to grapple with how to improve the official poverty measure,2

the federal government has yet to adopt any changes. Despite its short-comings, I rely on the official poverty measure in this analysis because ofits long-standing availability in the CPS and, more importantly, becauseit continues to be the official measure and is therefore the recognizedstandard for general policy assessment and benchmarking economicwell-being over time. It is also the measure utilized in the vast majority ofpoverty research.3

Various methods have been used to define the “working poor.” AsKasarda (1995:45) notes, “Counting the working poor is neither simplenor clean. This is because working is an attribute of an individual whilepoverty is defined in terms of the total income of the family to which theindividual worker belongs.” Most researchers have focused on whetheran individual worker hails from a family with an income below its respec-tive poverty threshold. But there has been less consistency in determin-ing who qualifies as “working,” with definitions ranging from full-time,year-round employment (i.e., 35 or more hours a week, 50 or moreweeks a year) to employment during just a single week in a given year(Blank and London 1995; Kasarda 1995; Klein and Rones 1989; Lichteret al. 1994; Morrissey 1991; Mosisa 2003). A common threshold has beento identify those employed 27 or more weeks (i.e., at least half) of theprevious year (Kasarda 1995; Klein and Rones 1989; Lichter et al. 1994),a cutoff that is not overly restrictive but does exclude nonworkers andthose with only marginal labor-market attachment.

Consistent with this approach, I define the working poor as thoseemployed at least half of the previous year (i.e., 27 or more weeks) andhailing from a poor family. I further restrict the analysis to family refer-ence persons between the ages of 24 and 64 years.4 The restriction to

3 In addition to the NAS recommended measure, it should be noted that researchershave employed an array of alternative poverty measures. These include measures thatassess the depth of poverty and income-to-needs ratios, relative poverty (e.g., less than halfof median family income), consumption, material hardship, and social exclusion (for anoverview see Iceland 2006). These approaches provide useful complements to the officialmeasure utilized here.

4 The “family reference person” is the person relative to whom the relationship of allother family members is recorded. In most cases (99.4 percent of the sample examinedhere), this person is the “householder.” The householder refers to the person (or one ofthe persons) in whose name the housing unit is owned or rented (maintained) or, if thereis no such person, any adult member, excluding roomers, boarders, or paid employees. Ifthe house is owned or rented jointly by a married couple, the householder may be eitherthe husband or the wife. In unrelated subfamilies (0.6 percent of the sample examinedhere) the family reference person is any adult relative to whom the relationship of all otherfamily members is recorded.

family reference persons was made for two reasons. First, I wanted toconsider the economic circumstances of all kinds of families, thoserelated to both the householder and members of unrelated subfamilies.5

This definition helps to capture the diversity of living arrangementsamong American families, particularly those who have chosen to“double-up” out of economic necessity. Second, I wanted to avoid thepotential confound of examining multiple workers from a single family,all of whom would share the same poverty status. The age restriction wasmade to keep the emphasis on those of “working age.” In sum, this is aconservative definition of the working poor as it focuses on the heads ofpoor families in the prime of their working years with significant attach-ment to the labor market.

Analytic Strategy

I approach the analysis by first examining descriptive statistics thatcompare the relationship between work and poverty in metro and non-metro areas over the period spanning 1979 through 2003.6 I then esti-mate a series of logistic-regression models that predict the likelihood ofa worker’s family being poor, with a special focus on the influences ofresidence, family labor supply, and period. The models assess the effectsof these three key sets of independent variables, net of the influence ofother important predictors of marginal employment and poverty. Thesecontrols include industry of employment, occupation, class of worker,sex, marital status, presence of own children, age, educational attain-ment, race/ethnicity, and region. Each is straightforwardly measuredand described in greater detail as it enters the analysis. The stratifiedcluster sampling design of the CPS necessitates the use of weights toproduce reliable population estimates. Because family reference persons

5 The CPS defines an “unrelated subfamily” as a family that does not include thehouseholder or relatives of the householder among its members. Members of unrelatedsubfamilies may include persons such as guests, boarders, or resident employees and theirrelatives living in a household. In keeping with the official poverty measure, this analysistreats all related family members in a given household as a single family with a singlepoverty status and unrelated subfamilies as separate families with their own poverty status.Unrelated individuals are excluded from the analysis.

6 The CPS also includes a small number of cases for which metro/nonmetro residenceis “not identified” to help protect confidentiality. These cases are excluded from theanalysis. It should also be noted that following the decennial census the Office of Man-agement and Budget reevaluates the metro/nonmetro status of each county in the UnitedStates and makes reclassifications as necessary. Therefore, an issue confronted in anyinterdecade study using the CPS is that the set of counties defined as metro and nonmetrois subject to change. The approach generally taken in such studies is to assess the circum-stances of people residing in conceptually similar settings over time, rather than people inthe same geographic units, which may become conceptually dissimilar as time passes.

are my unit of analysis, I use the March supplement person weights.However, to achieve more realistic tests of statistical significance, I dividethese weights by their means to yield weighted N’s approximately equalto the CPS sample size. To further adjust for the complex samplingdesign of the CPS, I also report statistical significance levels based onrobust standard errors using the method advocated by Davern et al.(2007). More specifically, I utilize the “surveylogistic” procedure in SASto make strata and cluster adjustments. I use the lowest level of identifi-able geography available in the CPS that can be applied to both metroand nonmetro populations (i.e., state) as the strata variable, and I usethe household ID as the cluster variable. The latter is an issue in only asmall number of cases (0.6 percent) where unrelated families reside inthe same household.

Prevalence of Working Poverty by Residence

Table 1 shows the percentage of working poor families as a share of allpoor families from 1979 to 2003. Data are presented for the entire UnitedStates and for metro and nonmetro areas specifically. Over the lastquarter century, nationwide the working poor have constituted between33.7 percent and 42.1 percent of all poor families headed by a working-ageindividual.7 Notably, the majority of poor families during this period were

7 For reference, population estimates from the 2004 CPS indicate that the definition ofthe working poor used here would apply to approximately 2.4 million workers in 2003.Importantly, note that the poverty status of these individuals extends to all related familymembers in their household.

not headed by individuals with substantial labor-market attachment,whether due to personal choice or structural obstacles. It is also notablethat the highest shares of the working poor were recorded in 1997 and2000. Because the latter 1990s were a period of unprecedented economicgrowth, one might presume that working poverty would fall as economicopportunity expanded. Indeed, poverty did fall to its lowest recorded levelduring this time. On the other hand, this finding could signal that theexpansion allowed more of the poor entrée to the labor market, albeit atlevels that did not allow their families to escape poverty—an interpreta-tion supported by the fact that the occupations in which the most jobswere created in the 1990s were low wage (Bernstein 2004). Thesenumbers could also reflect the impact of the welfare reform bill of 1996,which aimed to reduce welfare rolls and poverty by moving formerrecipients from “welfare to work.” These policies did slash welfare rolls toless than half their previous level, but may have transferred many from theranks of the welfare poor to the working poor.

The residence-specific trends underscore themes of both persistenceand change. From 1979 to 2003, working poverty was consistently higherin nonmetro than metro areas. The sole exception was in 1997, the yearfollowing welfare reform, when metro working poverty was a fraction ofa point higher than in nonmetro areas. Over the quarter century exam-ined, working poverty was 8.8 percent higher in nonmetro areas onaverage, with gaps approaching twice that size in some years. Thesenumbers provide support for prior research that showed the 1980s to bean unkind period for nonmetro workers (Lichter et al. 1994). As illus-trated in Figure 1, however, the data also show a trend of residentialconvergence in working poverty. The greatest inequalities existed in theearly 1980s, but since the middle part of that decade metro workingpoverty has steadily risen toward the levels observed in nonmetro areas.While this trend has been in motion since the late 1980s, it acceleratedbetween 1994 and 2000. As noted above, this was a period in which theUnited States experienced unprecedented economic growth, but wasalso when welfare reform was introduced. Given that the metro poorhave been shown to rely more heavily on public assistance than theirnonmetro counterparts (Jensen and Eggebeen 1994; Lichter and Jensen2002), this convergence may in part reflect the differential residentialimpact of welfare reform. It might also reflect trends in low-wage jobgrowth during this period (Bernstein 2004).

However, again, there is alsoevidence of residential convergence. After the first half of the 1980s—aparticularly unkind period for nonmetro workers—the residential gapnarrowed as the share of workers in poverty stabilized in nonmetro areasand trended upward in metro areas.

Multivariate Models of Working Poverty

Table 3 presents estimates from logistic-regression models predictingpoverty (1 = poor) among working family heads. I estimated models forthe nation as a whole and for metro and nonmetro areas separately. Theintent of these models is to examine the influence of residence, familylabor supply, and period effects on the likelihood of being poor. Themodels also control for a series of variables that have been shown to beimportant correlates of marginal employment and poverty, includingindustry of employment, occupation, class of worker, sex, marital status,presence of own children, age, educational attainment, race/ethnicity,and region.8 Specifically, I control for industry of employment with aseries of dummy variables measuring whether or not a worker’s job wasin extraction, manufacturing, transportation/utilities, trade (wholesale/

Following Lichter et al. (1994), Icontrol for occupation using dummy variables for whether or not aworker’s occupation is characterized as managerial/professional (refer-ence group), sales and clerical, service, or labor, with the expectationthat higher-status occupations will carry a lesser risk of poverty. I alsoconsider the effects of worker class with dummy variables measuringwhether one works for an employer in the private sector (referencegroup), public sector, or is self-employed. The expectation here is thatthe self-employed will face higher odds of poverty than will thoseworking for private- or public-sector employers (Lichter et al. 1994). Tocontrol for the important effects of family structure, the models includedummy variables for a worker’s sex (1 = male), marital status (nevermarried, widowed/separated/divorced, or married as the reference

group), and whether or not a worker’s family has children under the ageof 18 years living in the household (1 = yes). These variables are includedto control for the disproportionate risk of poverty faced by unmarriedwomen and their children (Bianchi 1999; Lichter and Jayakody 2002). Iinclude worker’s age as a continuous variable and dummy variables foreducational attainment (bachelor’s degree or more, some college, highschool diploma or equivalent, or less than high school as the referencegroup), race/ethnicity (non-Hispanic black, Hispanic, non-Hispanicother, or non-Hispanic white as the reference group),9 and region ofresidence (Midwest, South, West, or Northeast as the reference group).All of these variables have been shown to be important predictors ofpoverty and underemployment, demonstrating disadvantages associatedwith youth, less education, being black or Hispanic, and residing in theSouth (see Jensen and Slack 2003; Jensen et al. 1999; Lichter et al. 1994;Slack and Jensen 2002, 2008a, 2008b).

Table 3 shows that net of family labor supply, period effects, and thefull range of control variables, nonmetro workers have faced significantlyhigher odds of being poor than their metro counterparts over the lastquarter century. That is, nonmetro workers and their families have faceda disproportionate risk of economic hardship that is not explained byhow much their adult family members work, whether economic timesare good or bad (period effects), or other important sociodemographiccharacteristics that are common correlates of poverty. Not surprisingly,greater family labor supply is associated with significantly lower odds ofbeing poor. Workers who work full-time, full-year are significantly lesslikely to be poor than those who work less. Having additional full-timeworkers in the family also exerts significant downward pressure on thelikelihood of poverty, and to a lesser degree this is also true of additionalpart-time workers. Period effects are shown to be important predictors ofworking poverty, consonant with research that has shown the same forunderemployment (Slack and Jensen 2008b). In fact, the likelihood of aworker being poor has been significantly higher in every period exam-ined since 1979.

The residence-specific models show the same general pattern ofeffects. Among both metro and nonmetro workers, family labor supply isnegatively associated with the likelihood of being poor, while periodeffects since 1979 are positively associated with the probability of living in

9 Beginning in 2003, the CPS allowed individuals to identify themselves as a member ofmore than one racial group. In order to create racial and ethnic group definitions that areroughly consistent over the period examined, in the 2004 data I counted the small numberof mixed-race individuals as “other,” and limited the remaining groups to those identifyingas non-Hispanic white only, non-Hispanic black only, and Hispanic only.

poverty. However, tests for statistical significance between the corre-sponding coefficients for the metro and nonmetro models (see Clogg,Petkova, and Haritou 1995; Paternoster et al. 1998) indicate a number ofsignificant across-model differences. Notably, each of the family laborsupply variables provides significantly less downward pressure on povertyfor nonmetro workers than their metro counterparts. In other words,over the last quarter century, net of other significant factors, work hasprovided nonmetro families with less protection from poverty than hasbeen true for metro families. In addition, the models show that metroworkers struggled disproportionately in 2000, a finding reflective of thetrends observed in the descriptive analysis. Again, it is surprising to findevidence of increasing hardship for metro workers at the tail end of aperiod during which the United States experienced unprecedented eco-nomic growth, though while we witnessed very tight labor markets, thosesectors adding the most jobs during this time were low wage (Bernstein2004). It is also possible that welfare reform is at play here, given thegreater reliance on public assistance among metro poor than thenonmetro poor (Jensen and Eggebeen 1994; Lichter and Jensen 2002)and the great influx of workers into the low-wage labor market due tothis policy shift.

In order to delve deeper into how the circumstances of metro andnonmetro workers have changed over the 25 years in question, themodels presented in Table 4 compare the effects of family labor supplyon poverty in metro and nonmetro areas for three chronological timeperiods: 1979 to 1985, 1988 to 1994, and 1997 to 2003. To account forthe effects of time within each of the three periods, I include dummyvariables for the second and third year of observation in the models.Again, the models also include the full range of control variables out-lined previously. Substantively, these three periods allow for a number ofimportant comparisons. In the early 1980s (1979–1985), the gap inworking poverty was especially pronounced between metro and non-metro areas. During this period the share of poor families who wereworking poor was an average of 15.0 percent higher in nonmetro areas.In the latter part of that decade and into the early 1990s (1988–1994),that gap closed considerably, averaging 8.9 percent over that timeperiod. Between 1997 and 2003 the gap closed even further, averagingjust 2.5 percent. In addition, this last period also taps the post-welfarereform era.

Consistent with the results presented in Table 3, in each of the threetime periods family labor supply exerts significant downward pressure onpoverty in both metro and nonmetro areas. The results also suggest thatresidential differences in this effect have diminished over time. In the

period covering 1979 through 1985, tests for statistical significancebetween the corresponding coefficients for the metro and nonmetromodels show that full-time labor supply, by both the head and otherworkers, provided nonmetro families significantly less protection frompoverty than their metro counterparts. These tests also indicate that1985 was a particularly unkind year for nonmetro families. In the periodspanning 1988 through 1994, again full-time labor supply by nonmetroworkers shielded their families less from poverty than is true in metroareas. But in the period covering 1997 through 2003, significant differ-ences in the effects of labor supply between metro and nonmetro areascease to exist. Ancillary analyses show that if the period comparison isbetween pre-welfare reform (1979–1994) and post-welfare reform(1997–2003), the same pattern of effects holds. These results providefurther support that recent years have been a period of residentialconvergence in the relationship between work and poverty across themetro-nonmetro divide.

Conclusions and Implications

Geographic space is increasingly being recognized as a key dimension ofsocial inequality (Gans 2002; Lobao 2004; Lobao et al. 2007; Lobao andSaenz 2002; Tickamyer 2000). Scholars concerned with spatial inequalityhave called for special attention to issues of comparative advantage anddisadvantage across space as well as the consideration of the subnationalscale (Lobao 2004; Lobao and Hooks 2007; Tickamyer 2000). In particu-lar, these scholars have identified poverty analysis as providing “anexceptionally transparent example of the importance of spatial analysis,both negatively in the dangers of failing to examine variation by placeand space and positively in the benefits gained from such investigation.Poverty is gendered, raced, and spaced” (Tickamyer 2000:809).

Joining the consideration of both space and time, I examined resi-dential differences in working poverty between metro and nonmetroareas over the last quarter century. My results show that the relationshipbetween work and poverty across the metro-nonmetro divide has beensubject to both persistence and change. I find that working povertypersists in its disproportionate impact on nonmetro families. However,the results also show a trend of residential convergence, as workingpoverty in metro areas has risen toward the levels experienced in non-metro areas. Logistic-regression models exploring the effects of resi-dence, family labor supply, and period confirm that labor supply hasconsistently provided nonmetro families with less protection frompoverty than their metro counterparts over the quarter century in ques-tion, but also show that this disadvantage has waned in recent years.

The story of the changing relationship between work and povertyacross the metro-nonmetro divide would be a more optimistic one if thedata suggested that while nonmetro workers remain at a disadvantage,residential convergence has been driven by relative gains amongnonmetro workers. Unfortunately, it appears that the opposite istrue—metro working poverty appears to be trending upward toward thelevels observed in nonmetro areas. For a society that places great empha-sis on the value of the work ethic and views employment as the primarymechanism by which families are to avoid poverty and maintain eco-nomic self-sufficiency, this finding represents a troubling trend.

While these findings provide reasons for concern—to the degree thatthe working poor are viewed as among the “deserving poor”—they mayalso help motivate policies aimed at supporting low-wage workers. Suchpolicies would be particularly welcome news in rural America, wheremarginal employment has long been central to the poverty problem.One important policy intervention to help the working poor would be toraise the minimum wage beyond a poverty wage and, once this has beendone, make annual adjustments for increases in the cost of living.Putting more money in the pockets of the lowest-paid workers is astraightforward step that could be taken by Congress to help reduceworking poverty. Indeed, in recognition of congressional inaction onthis issue, voters across the nation have begun supporting referendumsto raise local and state minimum wages rates above that set at thenational level. Other important policy initiatives aimed at helping theworking poor include refundable tax credits, such as the EITC, as well aswork-support programs (Bernstein 2004). The EITC is already a success-ful and popular program (Gunderson and Ziliak 2004). Extending itfurther would raise the incomes of low-wage working families, whilesimultaneously encouraging greater work effort. Investments in worksupports, such as subsidies for transportation and childcare, wouldprovide important assistance to those working on the economic margins,as would investments in subsidies tied less directly to work, such as thoseaimed at offsetting housing and health-care costs. These policy consid-erations not only represent important ways to help fill the gaps for theworking poor but would also help increase the odds that those leavingthe welfare rolls are able to make the transition successfully. It is alsoimportant that policymakers recognize that the opportunity costs asso-ciated with work differ across spatial contexts. For example, in manyrural contexts there is no viable public transportation system, makingmaintaining and fueling a working vehicle a necessary cost associatedwith employment. In urban areas, where public transportation may bemore accessible, other opportunity costs may carry greater significance,

such as the high cost of housing. In a nation whose ethos is underpinnedby the idea that hard work pays off, it follows that those who work hardshould be able to avoid poverty’s grasp, and when the market fails toachieve this end, public supports should be crafted to fill the gap.
