Chapter 1 Study of Population
Population: Collectivity of people coexisting within a geographic territory at a
given point in time.
Demography: the study of population dynamics which investigate aggregate
manifestations (fertility, mortality, migration).
Census: Identifies the civilian population, total resident population and total
population living abroad.
Canada's census undercount is between 2-4%.
2 branches of demography:
Formal demography -Quantitative study of population in terms of growth,
distribution and development. Core questions are How many, What kind, where?
Population studies - Emphasis on identifying determinants and consequences of
demographic change. Core questions are How come and So What?
Static perspective: Focuses on demographic conditions at a fixed point in time.
Dynamic perspective: Change in demographic conditions over time.
Demographic components equation: P2 = P1 + (natural increaset1,t2) + (net
Models of population growth:
Linear- Assumes straight line progression over time. Rate of change is constant.
geometric- Growth follows non-linear trend. Population rises gently at first,
gradually picks up momentum producing increasing increments of population
over time. Growth compounds in intervals.
exponential- Growth follows non-linear t
