The Gross County Product per capita, or GCP per capita, is a measure of a county’s economic output that accounts for its number of people. It divides the county’s gross county product by its total population. The fact that the GCP per capita divides a county’s economic output by its total population makes it a good measurement of a county’s standard of living, especially since it tells you how prosperous a county feels to each of its residents.
