Chapter 6: Population Growth and Economic Development I. The Basic Issue: Poplation Growth and Quality of Life -by 2000, world pop was ca. 6.1 billion -pop is projected to be 9.2 billion by 2050 and max out at 11 billion in 2200 -Is rapid pop growth a serious problem in itself, or is it a manifestation of fundamental problems of underdevelopment and the unequal utilization of global resources between rich and poor nations??? -every year, ca. 80 million people are added to world pop; 97% are in developing nations II. Population Growth--Past, Present, and Future Population Growth Through History -ca. 5 million people 12000 years ago--> grew at an annual rate of not much more than zero -by 1750, pop growth was 150 times faster (0.3% instead of 0.002%) -growth increased to 1% by 1950, peaked at 2.35% in 1970 -today growth rate is 1.3%, and is slowing -famine, disease, malnutrition, plague, and war resulted in high death rates for most of history -in 20 th c., developmt. led to a huge decline in death rates but little or no change in birth rates Structure of the World’s Population -more than 75% of pop lives in developing countries, and LDCs have highest growth rates -Africa is projected to grow 184%, Latin America 70%, and Asia 50% *see graphs and tables on pages 267-269, esp. Figure 6.3 (crazy map) Fertility and Mortality Trends -rate of pop increase=yearly net pop increase due to natural increase and intl migration -pop increases in LDCs are mostly due to difference between birth and death rates -birth/fertility rates are generally much higher in LDCs than developed countries, and death/mortality rates are a bit higher but not to the same degree--> net growth -fertility has been declining slowly, but death rates are also declining -many LDC birthrates are even higher than preindustrial Western Europe’s rates were -children under 15 make up 31% of LDCs’ pop, only 18% of developed nations’ pop

--> higher youth dependency ratio (proportion of kids to working adults) --> LDC workforces must support almost 2x as many children The Hidden Momentum of Population Growth *population growth usually continues even after birthrates have fallen substantially--this momentum can last for decades -high birthrates now--> huge younger generation -when this generation reaches adulthood, the number of potential parents will be much larger than currently--> even if each mother has fewer children, the total number of mothers is so much greater that pop will continue to increase -so most LDCs are sure to have huge pop increases in future, even if fertility rates drop soon III. The Demographic Transition demographic transition : the process by which gertility rates eventually decline to replacement levels (2 kids per couple) -all developed nations have passed through the same 3 stages: (see Figure 6.7, page 275) 1) premodern: high birth and high death rates -- stable or slowly growing population 2) modernization: death rates drop but birth rates remain high -- huge pop growth 3) development: birthrates eventually fall too -- stable or slowly growing population
