1 Population & Urbanization

2  Identify factors that affect the size & structure of populations & explain how sociologists measure these factors.  Summarize how sociologists explain population change & describe the programs that have been instituted to control population growth.

3  the number of people living in an area at a particular time

4  area of sociology devoted to the study of human populations

5

6  annual number of live births per 1,000 members of the population Live Births  Birthrate = Total Population X 1,000

7  annual deaths per 1,000 members of the population  mortality: number of deaths within society  infant mortality rate: annual number of deaths among infants under one year of age per 1,000 members of the population

8  annual difference between in-migration & out-migration

9  the rate at which a country’s population is increasing  calculated by subtracting the death rate from the birthrate  usually expressed as a percentage

10  Thomas Malthus  geometric progression of population vs. arithmetic progression of food supply  Malthusian checks/limits:  war  disease  famine  natural disasters  population is based on technological advancement (capital)  3 main stages:  High BR, High DR  High BR, Low DR  Low BR, Low DR  zero-population growth = equal BR & DR Demographic Transition Theory Malthusian Theory

11  Malthus & Geography Malthus & Geography  Demographic Transition: Visual Model Demographic Transition: Visual Model

13  the conscious decision by couples to have a certain number of children  antinatalism: official policies used to discourage couples from having children

14  belief that better health, higher levels of income & education will lower birthrates  some argue that economic redistribution would reduce poverty and allow this to happen
