P2U1 01 Population Density and Distribution

Front

What is population density?

Back

The average number of people per square kilometer, indicating how sparsely or densely populated an area is.

Front

What is population distribution?

Back

Shows the differences in population density over an area and the way people are spread out.

Front

How is population density calculated?

Back

Population density = total population ÷ total land area in km².

Front

What are choropleth maps used for?

Back

To visualize population data by using different colors to show varying population densities across regions or countries.

Front

What is a disadvantage of choropleth maps?

Back

They do not show differences within specific countries.

Front

What are dot distribution maps?

Back

Maps that use dots to represent a certain number of people, showing the spatial distribution of population.

Front

What are graduated symbols maps?

Back

Maps that use symbols of varying sizes to represent the magnitude of a characteristic, such as the number of Walmarts per state.

Front

Name a physical factor affecting population distribution.

Back

Physical landscape, climate, diseases and pests, soils, resources and water supplies.

Front

How does climate affect population distribution?

Back

Reliable rainfall and abundant sunlight support food production and attract people, while extreme cold or unreliable rainfall can limit population density.

Front

What is the P.E.A. method for analyzing patterns on maps?

Back

P = Pattern, E = Extremes, A = Anomalies. Describe the overall pattern, name areas with highest and lowest values, and identify outliers.
