population density
measure of total population relative to land size
arithmetic population density
measure of the number of people within a given area divided by the total land area
physiologic population density
measure of the number of people per arable (farmable) land
agricultural population density
measure of the number of farmers per arable land
political
more laws, cities greater power/influence

more jobs, higher tax base, increase in poverty

environment
deforestation, less space/room, pollution, natural resource depletion
carrying capacity
the number of people an area can sustain without critically straining its resources
population pyramid
provides a visual representation of a population in terms of age and sex as well as a good indication of the dependency ratio within a country and is used to assess population growth and decline and to predict markets for
goods/services
rapid growth
distinguished by a wide base
stable/slow growth
characterized by a rectangular shape
declining/negative growth
the base is smaller than previous cohorts
disrupted growth
significant gaps in the pyramid, usually as a result of war, strict population policies, or other
drastic events
total fertility rate (TFR)
the average number of children a woman will have during her childbearing years (15-49)
birth rate
number of live births in a single year for every 1000 people (in a population)
replacement fertility level
2.1 (slightly higher than 2.0 to account for infant/childhood mortality/childless women)
mortality (death) rate
number of deaths in a single year for every 1000 people (in a population)
infant mortality rate
number of deaths during the 1st year of life (per 1000)
child mortality rate
number of deaths of between the ages of 1 and 5 (per 1000)
maternal mortality rate
number of deaths during or shortly after childbirth (per 100,000)
migration
involves a degree of permanence when moving to a new locale
emigration (out migration)
