World Population Increase Population growth, http://www.raisethehammer.org/index.asp?id=254
Video • What are some futurepopulation trends? • What are some areasincreasing or decreasingin population? Video – “Alarming Facts aboutthe Population of the World” (4 minutes) http://www.youtube.com/watch?v=UZWcoERjBUI&NR=1 Then checkout http://www.thefactlab.com/ 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 increase Total Fertility Rate (TFR):Average number of childrena woman will havein her childbearingyears (~15-49) • World rate is ~3 • Rate > 6 in some subSaharan countries • Rate <2 in ~ every European country TFR, http://www.ldeo.columbia.edu/edu/dees/V1003/lectures/population/index.html
To explain population increase Infant Mortality Rate (IMR): • Annual number of deathsof infants < 1 year against the total number of births • Per 1,000 • High in poor countries ofsub-Saharan Africa • In some LDC exceeds 100 (>10%) • Low in Western Europe • Only <50 (<5%) • Reflects standard of livingand medical facilities,and in-countrysocioeconomic status IMR, http://commons.wikimedia.org/wiki/File:Infant_mortality_rate_world_map.PNG
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 LE, http://upload.wikimedia.org/wikipedia/commons/6/6e/Life_expectancy_world_map.PNG

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 Population growth, http://www.unesco.org/education/tlsf/TLSF/theme_c/mod13/www.worldbank.org/depweb/english/modules/social/pgr/map1.htm
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 philosophy DT, http://www.globalchange.umich.edu/globalchange2/current/lectures/human_pop/human_pop.html
Demographic transition Note post-industrial (Jordan & Domosh)
Population pyramids Wide 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. PP, http://en.wikipedia.org/wiki/Population_pyramid

Looming Challenges • Overpopulation • Old populations • Peak phenomena (scarcity): • Food • Resources • Energy • Commodities • High prices • Declining economic development • Poverty • Climate change • Pollution • Famine / disease • War Old man, http://glorialimbong.files.wordpress.com/2008/06/poor-old-man.jpg
