To calculate per capita income, you must first know the Total Personal Income and the Population for the area in which you want to determine Per Capita Income.
To find the per capita income of an area, use the following formula:
pci = i/P
Where:
pci = per capita income
i = total personal income
P = total population
Example of per capita income calculation:
In 2006, the United States had a total personal income of $10,968,393,000,000. The total population of the U.S. in 2006 was approximately 300,000,000. Therefore, the per capita income of the United States in 2006 is:
pci = $10,968,393,000,000 / 300,000,000
pci = $36,561
