Per capita income is the average amount of money earned per person. It is often used to gauge the standard of living of people who live in a given area or who are members of a certain group.
The geographic pattern of per capita income can most easily be understood by creating a map. This map shows the per capita income for counties in West Virginia. It is one of a large number of interesting maps that can be found in the West Virginia Health Status Atlas, a website maintained by the West Virginia Department of Health and Human Resources.
