  1. World population, 1900-2000: poor share of total increased from 66% to 80%rich population doubled; poor almost fivefold Iraq 5.223.6 Afghanistan 5.0 (1900) 27.8 (2000)

  2. Demographic transitions compared, rich vs. poor countries: annual growth rates, 1700-2000

  3. Relation between TFR and e025 less developed countries, 1950-55: great diversity Iraq, tfr= 7.2; e0=43 Afghanistan tfr=6.7; e0=31

  4. Relation between TFR and e025 LARGE less developed, 1995-2000: transition well advanced Afghanistan tfr=6.0; e0=45 Iraq, tfr= 5.4; e0=58

  5. Strong inverse correlation between sewage system and 0-4 mortality in 55 poor countries, 1980s

  6. Per capita GDP and e0 in 25 less developed countries, 1995-2000: big increases at moderate levels of GDP

  7. DDT eradication halved the crude death rate in malarial zones of Sri Lanka, 1930-1960

  8. Burden of premature death and disease by world region, 1998: inequalities are large and larger yet between continents

  9. Contraception was major factor in reducing fertility from natural levels, 31 countries

  10. Per capita GDP and TFR, 25 less developed countries, 1995-2000—weak correlation

  11. Literacy and TFR, 25 less developed countries, 1980s—strong correlation Afghanistan tfr=6.0; illit=70% Iraq, tfr= 5.4; illit: 30%

  12. Fertility of married Mexican women by educational levels compared with natural fertility, 1990

  13. The educational revolution will precipitate further declines in Mexican fertility rates (1990) None Primary Secondary Post

  14. Decline in TFR by level of development and family planning, 1982-90: both required Test of unmet need thesis

  15. “Wanted” TFR vs. actual TFR, by region, late 1980s-early 1990s

  16. “Unwanted” children (%) vs. actual TFR, by region, late 1980s-early 1990sNo correlation

  17. % current contraceptors is strongly correlated with actual TFR, in all regions (late 1980s-early 1990s)

  18. % current contraceptors and “wanted” fertility: also strongly correlated, in all regions (late 1980s-early 1990s)

  19. Availability of contraception is not enough:% current contraceptors is not strongly correlated with unwanted children, in all regions (late 1980s-early 1990s)

  20. China, age structure: 1950 & 2025the effects of fertility decline

  21. India, age structure: 1950 & 2025the effects of partial fertility decline

  22. Increase in population and per capita GNP:27 less developed countries, 1970-92

  23. Increase in population 1950-70 & GNP pc:27 less developed countries, 1970-92

  24. Increase in population and per capita GNP:27 less developed countries, 1950-92

  25. Asia: the boom in labor force growth is over: much GREATER 1965-95 than for coming 30 years, except for Muslim countries

  26. Sub-Saharan Africa, the boom is underway: much GREATER IN COMING 30 years than for 1965-95 Increase in labor force, 1995-2025/1965-1995: Sub-Saharan Africa

  27. Gross investment and working age population selected countries

  28. Malawi: rapid fertility decline (from 7.6 in 1980 to 4.0) reduces schooling costs 50% by 2015—over modest fertility decline (tfr=5.5)2005, tfr= 6.5
