Population Studies Flashcards
population
the collection of people in a defined geographical area
population growth rate
the rate of population change in a specified time period, reported as a percent of the initial population
overpopulation
point where there are more people than can be sustained
carrying capacity
total possible population that can be supported with relevant resources and without significant negative effects in a given area
population projections
estimates of future populations made from mathematical extrapolations of previous data, usually based on birth/death/migration rates, do not consider unpredicted effects on population
crude birth rate (CBR)
the annual number of births per 1000 people in a population (10-20=low 40-50=high)
crude death rate (CDR)
the annual number of deaths per 1000 persons in a population (less than 10=low above 20=high)
rate of population change
the difference between the crude birth rate and crude death rate
age-specific birth rates/age-specific death rates
annual number of births/deaths per 1000 persons in an age group
fertility
ability of a woman to reproduce
fecundity
potential reproductive capacity of a woman
general fertility rate
the annual number of births per 1000 women in a population
total fertility rate
predicts the total number of births per single woman in a population with the assumption that the woman experiences the current recorded age-specific fertility rates and reaches the end of her reproductive life
replacement fertility rate
the fertility rate at which the population will remain balanced
sub-replacement fertility
indicates that the birth rate is less than the death rate, thus the population size will not be sustained
population-lag effect
changes in total fertility rates are often not reflected in the birth rate for several generations, result of population momentum
population momentum
the children produced during periods of higher fertility rates reproduce; there are more women of reproductive age and thus more births overall, regardless of the number of births per women
mortality
the death rate in a population, includes both general and specific measures
morbidity
the nature and extent of disease in a population
prevalence rate
measures the number of individuals experiencing a disease
incidence rate
measures the number of new cases of a disease
case fatality rate
measures deaths as the result of a set diagnosis or procedures, sometimes specific to the beginning or late stages
infant mortality rate
the annual number of deaths per 1000 infants under one year of age
life expectancy
the number of years that an individual at a given age can expect to life at present mortality rates
migration
the geographical movement of individuals, families, or other small or large groups of people, implies the intention of permanent relocation
nomadism
traditional method of continuous travel in search of natural resources as a method of sustenance (no intention to settle)
external migration
cross-border or international migration, involves migration to another nation
internal migration
involves migration to another region of the same nation
voluntary migration
the result of internal factors (a personal decision)
involuntary migration
forced migration that is the result of external factors that pose a threat to the individual in their initial environments and are often a form of social control
settlers
those who migrate to an unsettled area
refugees
those who migrate to settled areas as a result of displacement
colonization
involves migration to settled areas in which dominance is exerted over the foreign state
immigration
involves entering a new area and these people are often called immigrants
emigration
involves leaving an old area, these people are called emigrants
reverse migration
return migration, the return of individuals to their former homes
push factors
those unattractive about an area that push people to leave, component considered in migration
pull factors
things that are attractive about an area, component considered in migration
social geography is interested in:
the spatial distribution of individuals and social groups
urbanization
the growth of urban areas as the result of global change
industrialization
the process through which societies transform from agrarian to industrial in nature
rural flight
(rural exodus), studies the migration from rural areas to urban areas
suburbanization
refers to population growth on the fringes of urban areas, as people move from urban areas to suburban areas
suburbs
residential satellite communities located in the peripheral regions of major urban centres that are often connected to the cities in some fashion
