SOCA02H3 Chapter Notes - Chapter 20: Malthusian Trap, Urban Sociology, Human Ecology
Document Summary
Demographers are social-scientific analysts of human population. Malthusian trap refers to a cycle of population growth followed by an outbreak of war, pestilence, or famine that keeps population growth in check. Demographic transition theory explains how changes in fertility and mortality affected population growth from pre-industrial to post-industrial times. Crude death rate is the annual number of deaths per 1,000 people in a population. Crude birth rate is the annual number of live births per 1,000 people in a population. Cultural lag refers to the gap that occurs between rapid technological change and slower changes in norms and values. Replacement level is the number of children that each woman must have on average for population size to remain stable, ignoring migration. Immigration or in-migration, is the inflow of people into one country from one or more other countries and their settlement in the destination country.
