Per capita
Two common measurements of the average annual income of individuals in the United States are: per capita income (PCI) and per capital personal income (PCPI). Per capita personal income is the more comprehensive of the two measures, and thus PCPI for an individual, county, or state will be higher than PCI. The difference between the two measurements is substantial. In 2019, for example, the per capita income of the United States was estimated at $34,103. The per capita personal income was estimated at $56,469.
