Physiologic Population Density
The number of people per unit area of arable land.
Population Composition
Structure of a population in terms of age, sex and other properties. (ex. marital status and education)
Age-Sex Pyramid
A graphic representation of the age & sex of a population.
Crude Birth Rate (CBR)
The total number of live births in a year for every 1,000 people alive in the society.

A model of the effect of economic development on population growth based on births, deaths, and other statistics.
Doubling Time
The number of years needed to double a population, assuming a constant rate of natural increase.
Exponential Growth
Growth pattern in which the individuals in a population reproduce at a constant rate.
Linear Growth
Expansion that increases by the same amount during each time interval.
Natural Increase
The growth rate of a population; the difference between birthrate and death rate.
Population Explosion
The rapid growth of the world's human population during the past century.
Stationary Population Level (SPL)
The level at which a national population ceases to grow.
Absolute Direction
A compass direction such as north or south.
Relative Direction
Direction based on a person's perception of an area.
Absolute Distance
The distance that can be measured with a standard unit length, such as a mile or kilometer.
Relative Distance
Approximate measurement of the physical space between two places.
Push Factors

Pull Factors
Positive conditions and perceptions that cause residents to move in.
Activity (Action) Space

Step Migration
Migration to a distant destination that occurs in stages. (ex. from farm to nearby village and later to a town and city)
Counter Migration
Migration back to an original area in which people had left. (ex. migration increases after natural disasters, yet many eventually return after a time)
Intervening Opportunity
The presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away.
Distance Decay
The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin.
Refugee

Eugenic Population Policy
Government policy designed to favor one racial sector over others.
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. (ex. Chinese can only have 1 child)
Negative Population Growth
The decline in population due to less than replacement births or extensive deaths.
