APHG Population
Term | Definition |
---|---|
Population Density | Population per area. |
Demographic Regions | Regions grouped together by the stage of the demographic transition model that most countries in the region are in. |
Population Distribution | 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. |
Population Explosion | 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. |
Age Distributation | 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. |
Cohort | a category of people with something in common, usually their age. (like a generation) |
Sex Ratio | The amount of males to girls in a population. |
Gendered Space | 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. |
Maladaptation | 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. |
Sustainability | 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. |
Dependency ratio | 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. |
Doubling time | The number of years needed to double a population, assuming a constant rate of natural increase. |
J-curve | Exponential growth curve. |
S-curve | Logistic growth curve. |
Ecumeme | The portion of Earth's surface occupied by permanent human settlement. |
Overpopulation | The number of people in an area exceeds the capacity of the environment to support life at a decent standard of living. |
Under population | Circumstances of too few people to sufficiently develop the resources of a country or region to improve the level of living of its inhabitants. |
Carrying capacity | largest number of individuals of a population that a environment can support. |
Population Projection | a statement of a population's future size, age, and sex composition based on the application of stated assumptions to current data |
Demographic momentum | 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. |
