|Population per area.
|Regions grouped together by the stage of the demographic transition model that most countries in the region are in.
|How population is spread out in an area.
|Natality - Birth rate
|The number of live births divided by the population.
|Mortality - Death rate
|The number of deaths per thousand people.
|The rapid growth of the world's human population during the past century.
|Zero population Growth (ZPG)/Stationary population level
|When birth rate is equal to death rate.
|A model used in population geography that describes the ages and number of males and females within a given population; also called a population pyramid.
|Population pyramid/ Age-sex Pyramid
|A bar graph representing the distribution of population by age and sex.
|a category of people with something in common, usually their age. (like a generation)
|The amount of males to girls in a population.
|Areas or regions designed for men or women.
|Standard of Living
|The quality of life based on the possession of necessities and luxuries that make life easier.
|Infant Mortality Rate
|The number of deaths in the first year of life for every 1,000 live births.
|Diffusion of fertility control
|The diffusion of fertility control is spread throughout the world.
|An adaptation that is less helpful than harmful; It can also signify an adaptation that, whilst reasonable at the time, has become less and less suitable and more of a problem or hindrance in its own right, as time goes on.
|The ability to keep in existence or maintain. A sustainable ecosystem is one that can be maintained.
|Demographic equation (change)
|An equation that summarizes the amount of growth or decline in a population within a country during a particular time period taking into account both natural increase and net migration.
|The number of nonworking members compared to working members for a given population.
|Rate of natural Increase
|Birth rate minus the death rate, suggesting the annual rate of population growth without considering net migration.
|The number of years needed to double a population, assuming a constant rate of natural increase.
|Exponential growth curve.
|Logistic growth curve.
|The portion of Earth's surface occupied by permanent human settlement.
|The number of people in an area exceeds the capacity of the environment to support life at a decent standard of living.
|Circumstances of too few people to sufficiently develop the resources of a country or region to improve the level of living of its inhabitants.
|largest number of individuals of a population that a environment can support.
|a statement of a population's future size, age, and sex composition based on the application of stated assumptions to current data
|The tendency for growing population to continue growing after a fertility decline because of their young age distribution. This is important because once this happens a country moves to a different stage in the demographic transition model.
