carrying capactiy
Carrying Capacity: the maximum population size of a species that the environment can sustain indefinitely, given the available resources such as food and water. The number of people that a region can support without environmental degradation.
5 major agglomerations
5 Major Agglomerations: Human populations are clustered, people live where it is most convenient.
overpopulation
Overpopulation: the number of people exceeds the capacity of the environment to support life at a decent standard of living.
demography
Demography: the scientific study of population characteristics.
cartogram
Cartogram: a map on which statistical information is shown in diagrammatic form.
census
Census: a complete enumeration of a population.
ecumene
Ecumene: the portion of Earth’s surface occupied by permanent human settlement.
non ecumene
Non-Ecumene:the portion of Earth’s surface which is not inhabited by humans.
arithmetic density
Arithmetic density: the total number of objects in an area.
population density
Population Density: the number of people living within an area.
population distribution
Population distribution: the share of inhabitants by types of regions in a given country.
arable land
Arable land: land suited for agriculture.
physiological density
Physiological density: the number of people per unit area of arable land.
agricultural density
Agricultural density: the ratio of the number of farmers to the amount of arable land.
natural increase rate (NIR)
Natural Increase Rate (NIR): the percentage by which a population grows in a year.
natural increase rate (NIR)
Natural Increase Rate (NIR): the percentage by which a population grows in a year.
doubling time
Doubling Time: the number of years needed to double a population, assuming a constant rate of natural increase.
population explosion
Population Explosion: the rapid increase of a number of people living in an area.
crude birth rate (CBR)
Crude Birth Rate (CBR): the total number of live births in a year for every 1,000 people alive in the society.
total fertility rate (TFR)
Total Fertility Rate (TFR): measures the number of births in a society.
infant mortality rate (IMR)
Infant Mortality Rate (IMR): the annual number of deaths of infants under one year of age, compared with total live births.
natality rate
Natality Rate: number of births per 1000 individuals per year.
demographic equation
Demographic Equation: the global difference between births and deaths.
demographic transition model
Demographic transition model: changes in the natural increase rate as a function of economic development.
