Title: World population, 1900-2000: poor share of total increased from 66% to 80% rich population doubled; poor almost fivefold


1
World population, 1900-2000 poor share of
total increased from 66 to 80rich 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 e0 25 less developed
countries, 1950-55 great diversity
Iraq, tfr 7.2 e043
Afghanistan tfr6.7 e031
4
Relation between TFR and e0 25 LARGE less
developed, 1995-2000 transition well advanced
Afghanistan tfr6.0 e045
Iraq, tfr 5.4 e058
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, 1995-2000weak correlation
11
Literacy and TFR, 25 less developed countries,
1980sstrong correlation
Afghanistan tfr6.0 illit70
Iraq, tfr 5.4 illit 30

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

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)
