World Population, http://people.howstuffworks.com/population-six-billion.htm

Population “doubling time”• Small changes in populations increase have

dramatic effects• NIR of:

– 1.0% doubles population in 70 years– 1.4% doubles population in 51 years– 2.2% doubles population in 35 years

Where is the populations increase?• Mostly LDCs in:

– Africa– Asia– Latin America– Middle East

• In last decade worldpopulation growth:– 2/3 in Asia– 1/3 divided equally

among:• Sub Saharan Africa• Latin America• Middle East

NIR, http://www.countrywatch.com/facts/facts_default.aspx?type=image&img=PIAG

To explain population increaseTotal Fertility Rate (TFR):

Average number of childrena woman will havein her childbearingyears (~15-49)

• World rate is ~3• Rate > 6 in some sub

Saharan countries• Rate <2 in ~ every

European country

TFR, http://www.ldeo.columbia.edu/edu/dees/V1003/lectures/population/index.html

To explain population increaseInfant Mortality Rate (IMR):• Annual number of deaths

of infants < 1 year against the total number of births

• Per 1,000• High in poor countries of

sub-Saharan Africa– In some LDC exceeds 100

(>10%)• Low in Western Europe

– Only <50 (<5%)• Reflects standard of living

and medical facilities,and in-countrysocioeconomic status

To explain population increase

• Life expectancy at birth measuresthe average numberof years a newborninfant can expectto live– High in MDCs

• Western Europe

– Low in LDCs• Sub-Saharan Africa

Young populations

Young populations, http://arbroath.blogspot.com/2006_12_03_archive.html

Brief review• MDCs have:

– Higher life expectancy– Older populations– Lower rates of:

• Natural increase• Crude birth• Total fertility• Infant mortality

• LDCs have:– Lower life expectancy– Younger populations– Higher rates of:

• Natural increase• Crude birth• Total fertility• Infant mortality

Demographic Transition• Typical Stages of Process of Development

– 1. High BR and DR, stable population– 2. Rapidly falling DR population increase, urbanizing – 3. BR decline as DR continue to decline moderation

of population increase– 4. Low BR and DR population stability (or decrease)

Influenced by:

•Industrial Revolution

•Medical Revolution

•Wealth

•Infrastructure

•Social philosophyDT, http://www.globalchange.umich.edu/globalchange2/current/lectures/human_pop/human_pop.html

Note post-industrial

Demographic transition (Jordan & Domosh)

Population pyramidsWide base shows large number of children, but rapid narrowing as many die between each age band. The pyramid indicates a population with high BR, high DR and short life expectancy. Typical for poorer countries - little access to birth control, poor environmental factors (e.g. no clean water), minimal health services. Note more females than males in age groups – females live longer.

Looming Challenges• Overpopulation• Old populations• Peak phenomena

(scarcity):– Food– Resources– Energy– Commodities

• High prices• Declining economic

development• Poverty• Climate change• Pollution• Famine / disease• War
