Study Notes
- Population distribution is the arrangement of people in an area.
- Demographers use population distribution to refer to how people are arranged in a given area.
- Only 29% of the world’s surface is land, and less than half of that land supports settlements.
Population Distribution Patterns
- Clustered populations live in close groupings, notably in South Asia, Europe, and Southeast Asia.
- Scattered populations are spread with great distances between settlements, like in Siberia, Russia.
- Linear settlements form a line, like those along the Nile River in northeastern Africa.
- Peripheral distribution involves major cities along the coasts, as common in South America.
Population Density
- Population density is the number of people in a given area.
- To calculate population density, divide the number of people by the land area (people ÷ km²).
- Singapore's population density is 7614.8 people per km², while Mongolia's is 1.9 people per km².
- Dense populations have large numbers of people in a small area, and sparse populations have few people in large areas.
Settlement Hierarchy
- Settlement hierarchy describes the relative sizes of settlements.
- The order is as follows: Hamlet (under 100 people), village (at least 100), town (at least 1000), and city (at least 100,000).
- The largest is a megacity with up to 10 million.
- As settlement size increases, so does the number of functions and services available.
Choropleth Maps
- Choropleth maps use shades of color to show the range of data within a geographic area.
- They are commonly used to display population density.
Patterns and Trends
- Geographers use settlement characteristics such as location, landforms, population size/density, and population distribution to understand and predict trends.
- These predictions determine how a settlement and its population change over time.
Population Patterns
- Population patterns are described as urban or rural, growth rates, distribution (clustered, scattered, linear, or peripheral), and density (sparse or dense).
- Governments use demographic information to plan services and make sustainable decisions.
