| Term | Definition |
|---|---|
| agricultural density | The ratio of the number of farmers to the amount of arable land |
| anti-natalist policy | attempt to decrease the number of births in a country and are often used by developing countries |
| arable land | land capable of being ploughed and used to grow crops |
| arithmetic density | The amount of people per unit area of all land |
| carrying capacity | The maximum population an environment can sustain without environmental damage |
| crude birth rate | the number of live births occurring in area per 1,000 people in 1 year in a country |
| crude death rate | The number of deaths occurring among 1000 people of a given geographical area during a given year |
| demographic momentum | A phenomenon in which a country with a large percentage of young people (usually a less developed country) typically will have a continued population growth. Once the young people grow beyond a child-bearing age, the population will overall decrease. |
| demographic transition model (DTM) | shows 5 typical stages of population change that countries experience as they modernize |
| demography | study of statistics like births, deaths, income, or the incidence of disease, illustrate the changing structure of human populations |
| dependency ratio | a measure of the portion of a population which is composed of people who are too young or too old to work |
| doubling rate | the period of time it takes for the population to double in size |
| ecumene | The portion of Earth's surface occupied by permanent human settlement. |
| Epidemiologic Transition Model | model that explains the shift in cause-of-death patterns that comes with the over-all decline of death rates; pairs with the demographic transition theory |
| infant mortality rate | number of deaths among babies under one year of age for each thousand live births in a given year |
| life expectancy | A figure indicating how long, on average, a person may be expected to live |
| maternal mortality rate | the death of a woman from pregnancy related causes during pregnancy or within 42 days of pregnancy per 100,000 live births |
| Natural Increase Rate | percentage at which a country's population is growing or declining without the impact of migration |
| Negative Population Growth | population is actually decreasing in a country because people aren't having enough babies to replace the amount of people dying |
| Neo-Malthusians | People today who have applied Malthus' basic ideas(Malthusian Theory of Population) to modern conditions |
| Pandemic | an outbreak of a disease that is spread over a country or the world |
| Physiological Density | the number of people per unit area of arable land |
| Population Pyramid | A model used in population geography to show the age and sex distribution of a particular population |
| Pronatalist Policies | government policies that encourage child birth (increase the fertility rate) such as tax breaks and flexible work hours |
| Replacement rate | the total amount of births needed for a population to replace itself EXAMPLE: The average replacement rate is from 2.1 to 2.5 in most countries |
| sex ratio | the ratio of males to females in a population |
| Thomas Malthus | an English scholar who created a theory -It stated that population growth will eventually outrun our food supply so there must be a restriction on human reproduction |
| Total Fertility Rate | The average number of children who would be born per woman of that group in a country, assuming every woman lived through her childbearing years(15-49) |
| Zero Population Growth | occurs when the birth rate equals the death rate, when the population of a country stops increasing |
