Broad Outline• Analysis of developments in income and health “poverty”
over the 2003-2011 period• Analysis of poverty in both dimensions and also correlation
between the two• Also analysis from time-series and cross-section
perspective• Income poverty falls up to 2009, then increases• Health poverty unchanged• Evidence that health inequality decreased• Health/income correlation amongst poor has declined• More detail available in full version of paper (ungated
version at http://www.ucd.ie/t4cms/WP13_05.pdf)

Context (1)• Are recessions good for your health?• Ruhm (2000) said “yes”, but Ruhm (2013) said “maybe”• Chang/Stuckler (2013), Great Recession led to excess
suicides• Not consistent with Walsh and Walsh (2011) for Ireland, also
challenged by Denny (2013)• Deaton (2011), Walsh (2011) – difficulties in relating
movements in SWB to economic cycle• Different dimensions of health may respond differently to
economic cycle• We look at micro-based data, self-assessed health (SAH) • Also issue of income-health correlation within a given cross-
section

Context (2)• Measuring welfare/poverty across multiple
dimensions• Intersection or union approach?• Alkire-Foster attempt to overcome this• Multi-dimensional indices• Gives single index, but black box? Weights?• Dashboard approach – provide information on 2
(at most 3) indices and summary of their correlation
• This talk focuses on measurement – we do not look at explanatory factors

Data• 9 waves of Survey of Income and Living Conditions (SILC)
• Nationally representative sample with information on sources of income, deprivation, health
• Income measure: equivalised disposable income (i.e. including social transfers and with taxes/pension contributions deducted)
• Health: “in general, how good would you say your health is?” Very bad, bad, fair, good or very good
• Good predictor of subsequent morbidities/mortality
• Analysis confined to over 16s (under 16s not asked health question)
• Sample size c.10,000 p.a.

The story so far...
• Income poverty falls up to 2009 and then increases
• Health poverty broadly unchanged over period
• Some evidence of marginal reduction in overall health inequality from 2009
• What if we look at them together?

Summary
• No evidence that recent recession has been accompanied by meaningful deterioration in health (self-assessed)
• Health inequality seems to have slightly diminished
• Correlation between health and income within the poor (for each cross-section) has declined
• Note these are only two dimensions of welfare (albeit important ones)
• Other health measures?• Also, early days – health effects of recession
could operate with a lag
