 The United States Census Bureau takes the total income for last year only for people above 15 years and above and then calculates the median average of the data. It is calculated by dividing the total income of the area by its total population.
Examples of Per Capita Income (with Excel Template)
Let’s see some simple to advanced practical examples to understand it better.
Example #1
The modern town has a total population of 100 people who are earning $4,50,000 per year engaged in primary agricultural activities and 5,000 people earning $35,000 per year engaged in manufacturing activities. You are required to calculate the per capita income of modern town.
Solution.
Per Capita Income = Total Income of Area/Total Population
Calculation of total income of modern town
 = (100 * 4,50,000) + (5,000 * 35,000)
 = $4,50,00,000 + $17,50,00,000
 Total Income = $220,000,000
And, Total population will be
 = 100 + 5000
 Total Population = 5100
Calculation can be done as follows
 = 220000000/5100
Example #2
Suppose In a city there are 10,000 workers working at different pay scales.
You are required to calculate per capita income
Solution.
 = (500 * $50,000) + (2,500 * $30,000) + (2,000 * $20,000) + (5,000 * $5,000)
 = $2,50,00,000 + $7,50,00,000 + $4,00,00,000 + $2,50,00,000
 Total Income = $16,50,00,000
Calculation of total population
 = 500+2,500+2,000+5,000
 Total Population = 10,000
 = 16,50,00,000/10000
Per Capita Income will be –
Example #3
Suppose there are 5 companies in a city. The number of employees and the income of the companies are as follows.
Calculate per capita income of the City.
Solution: To arrive at the per capita income of these companies, we need to perform the necessary calculations shown below.
Calculation of total income
 = (25,000 + 2,00,000 + 80,000 + 50,000 +1,75,000 – 50,000 + 0)
 Total Income = 4,80,000
And, calculate the total population
 = 800+500+100+200+400+500+100
 Total Population = 2,600
 = 480000/2600
