The study of human population
A periodic and official count of a country's population
The number of individuals per unit area
Arithmetic population density
The population of a country or region expressed as an average per unit area. The figure is derived by dividing the population of the areal unit by the number of square kilometers or miles that make up the unit
Physiologic population density
The number of people per unit area of arable land
Structure of a population in terms of age, sex and other properties such as marital status and education
Snapshots of the age structure of a population at some period in time
Crude birth rate
The number of children born per 1000 people
Crude death rate
A ratio of number of death in a year to every 1000 people.
A figure that describes the number of babies that die within the first year of their lives in a given population
Total fertility rate
A measure of the reproductive status of a population
High birth rates and death rates are followed by plunging death rates, producing a huge net population gain; this is followed by the convergence of birth rates and death rates at a low overall level.
The number of years needed to double a population, assuming a constant rate of natural increase.
Growth of a population that multiplies by a constant factor at constant time intervals
Arithmetic growth; increases at a constant amount per unit time
Population growth measured as the excess of live births over deaths; does not reflect either emigrant or immigrant movements
The rapid growth of the world's human population during the past century, attended by ever-shorter doubling times and accelerating rates of increase
Stationary population level
The level at which a national population ceases to grow.
The EXACT way or direction to get to something (north,south,east,west)
Directions such as left, right, forward, backward, up, and down
The distance that can be measured with a standard unit length, such as a mile or kilometer.
A measure of distance that includes the costs of overcoming the friction of absolute distance separating two places. Often it describes the amount of social, cultural, or economic, connectivity between two places.
Negative conditions and perceptions that induce people to leave their adobe and migrate to a new location
Positive conditions and perceptions that effectively attack people to new locations from other areas
The space within which daily activity occurs.
Migration with a closed route and is repeated annually or seasonally. Usually lasts a few weeks to a couple months.
A way of life, forced by a scarcity of resources, in which groups of people continually migrate to find pastures and water.
Movements that are taken based on a seasonal basis.
A movement from one country or region to another
Migration from a place
Human migration flows in which the movers have not choice but to relocate
Movement in which people relocate in response to perceived opportunity; not forced.
Human movement within a nation-state, such as going westward and southward movements in the US.
Migration across an international border.
Movement from one region of a country to another
Migration to a distant destination that occurs in stages, for example, from farm to nearby village and later to a town and city
Migration back to an original area in which people had left
The presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away
The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin
Person who flees to another country to escape persecution or disaster
Refugees encamped in a host country or host region while waiting for resettlement.
Refugees who have been substantially integrated into the host country or host region and who are thus seen as long-term visitors.
Refugees who have crossed one or more international boundaries during their dislocation, searching for asylum in a different country
Refugees who have abandoned their town or village but not their country
Laws and regulations of a state designed specifically to control immigration into the state
Eugenic population policy
Government policy designed to favor one race over another
Expansive population policy
Government policy that encourages large families and raises the rate of population growth
Restrictive population policy
Government policy designed to reduce the rate of natural increase
Negative population growth
The actual decline in population due to less than replacement births or extensive diseases
