APHUG UNIT 2A Flashcards
Population Distirbution
Pattern of human settlement, represents crowded, sparsely settled, or even empty places
Population Density
Measure of the average population per square mile or kilometer. Measures how crowded a place is without considering distribution.
Midlatitudes
30* to 60* degrees north and south of the equator. Most people live here. These areas have moderate climates and better soil.
Low-Lying Areas
Areas low in elevation. People live in these areas because of convenience, better soils for crops, closer to the ocean, moderating temperature.
Social Stratification
Hierarchical division of people into groups based on factors such as economic status, power, and/or ethnicity.
Arithmetic Population Density
(Total Population/Total Area), tells you how many people are in an area per square mile or kilometer.
Even Distirbution
People are evenly dispersed.
Cluster Distirbution
People are clustered/agglomerated in one part of an area. Common when people live near a central feature.
Linear Distribution
People are spread out in a line. Common for people who live along a river or transit route.
Physiological Density
(Total Population/Arable Land), shows the pressure the people put on the land. Shows reliance on imports if it is high.
Agricultural Density
(Farmers/Arable Land), indicates the efficiency of the regions farming. Developed countries have lower agricultural densities because farmers can make more with technology.
Redistricting
Boundary adjustments towards physically smaller urban districts and larger rural districts. This happens because urban areas increase in population, rural areas shrink in population.
Infrastructure
Facilities and structures allowing people to carry out their typical activities. (E.G. Roads)
Overpopulation
A region having more people than it can support. The threshold for this happening depends on the regions carrying capacity.
Carrying Capacity
Number of people a region can support without damaging the environment.
