Chapter 8- Population Dynamics
Measures of Growth
exponential growth method
Doubling time
Linear growth method
Natural Increase (births-deaths)
Difference Method
Net Migration (in- and out- migration)
Component Method
Demographic Transition
Stage 2
Mid 17th Century, founding of modern science (Newton), modern technologies (morality control)
Stage 3
Intentional decrease in fertility, family planning, and value shifts including birth control
Stage 1
Population growth rates were low because of high morality
Stage 4
Europe's growth is slow and uneven. Birth rates will more than likely fall below death rates.
After WW2, medical and health innovations were far more advanced. Sanitation was also improved and helped develop less-industrialized countries
Redistribution
Average life expectancy at birth, and migration patterns were closely related back to each specific region/country
Population Momentum- population growth even when fertility levels were to fall below replacement levels
United Nations' World Population Prospects (high, medium, and low)
Europe's transition from high to low rates of growth transformed them into an industrial society. From Gemeinschaft to Gesellschaft.
Information from the past, and present, historians have questioned the the argument that socioeconomic development is strongly linked to fertility decline
A drop in voluntary fertility characterizes transition in the less-industrialized areas today

indicators: median age,, proportions in cohorts, dependency ratios, mortality levels.
