What is Per Capita Income? Insights, Uses, and Limitations


Understanding the Concept of Per Capita Income

Per capita income is a type of economic barometer that is used to quantify an individual's income within a defined set of monetary units, such as a city, province, country, geographic region, area, sector, and other varied elements, during a specified period. To assess the quality of life of a population living in a certain geographic area at a given time, it usually looks for the median income that an individual produces. We will look at the definition, formula, and calculation of per capita income in this guide.

What is Per Capita Income?

The average income received by each member of a certain community or region is measured as per capita income. It is computed by dividing a nation's or region's total income by its total population. A well-known economic metric, PCI aids in estimating and comprehending the quality of life and level of living for a community or people. Per capita income, as opposed to other economic measurements of income that account for employment, takes into consideration every person within a population or geographic area. It suggests that while calculating PCI, people without jobs—such as children and the homeless—are also taken into account. Therefore, per capita income is a less accurate indicator of the average national income than the average employment income per country.


Applications of Per Capita Income

  • GDP Per Capita: GDP per capita is a metric used to calculate the economic production of a nation based on its population. The total domestic output of your nation is divided by the population to determine its GDP. The following is the GDP formula: GDP per capita is equal to GDP/population.

  • Gross National Income Per Capita: Using a similar procedure to obtain GDP per capita, you can also find out a country's gross national income per capita. You can use the same data used to compute GDP to get the gross national income per capita, plus any income people receive from foreign investments.


Uses of Per Capita Income

Per capita income has multiple applications and is a potent economic tool. Here are a few of the best ways to employ per capita income for the economy. 

  • The per capita income of a given country or region reveals the disparity in income. Higher per capita income nations have an equitable distribution of income, whereas lower per capita income nations have an uneven distribution. 

  • It also serves as a potential indicator of a nation's economic development in terms of the level of living and general financial well-being of the populace. 

  • The formula for per capita income is used by a nation's officials to create a variety of population-specific economic strategies. They are able to focus more on the particular regions that need economic growth as a result. 

  • Among the most important motivators are choices on investments and marketing. Assuming demand for their product and exposing the purchasing power of the populace in a certain area, per capita income assists investors and marketers in making well-informed selections.


Limitations of Per Capita Income

Despite being a crucial instrument for economic analysis, it has many drawbacks, which are covered in more detail below: 

  • The per capita income formula is not a reliable indicator of the level of living in a given region because it divides the total income of each individual resident by the whole population. Stated differently, it fails to present an accurate depiction of the quality of life in that region. 

  • Per capita income does not represent a nation's inflation. For example, a country's annual revenue will increase by 10% if its per capita income increases by 10% over the preceding year. It does not, however, account for the rate of inflation. In actuality, the income would increase by 7% rather than 10% if the rate of inflation is 3%. 

  • The disparities in the cost of living might lead to inaccurate comparisons between countries. This is mostly due to the computation not taking the currency rate into account. 

  • Per capita income ignores people's wealth and savings, which is another disadvantage of the statistic. For example, an individual from a wealthy family may have a low yearly salary, but they can use their savings to support a high standard of living. As a result, the wealthy would appear to have low income according to the per capita income.

  • The fact that children make up a large portion of the population and could be candidates for wage labour is one of the most significant disadvantages. As a result, they just raise the population's total number living in a nation and divide it by the population's total yearly income. 

  • The welfare of the populace, which includes things like better working conditions, health benefits, and the total amount of working hours, among many other things, is not captured by income per capita. It thereby misrepresents the general welfare of the community. 


Formula for Per Capita Income

The majority of the Per Capita Income computation consists of the total income earned by each individual and by the entire population. Consequently, the first step in calculating the per capita income formula is to divide the region's total revenue by the number of residents.

Per Capita Income = Total Income of the Area / Total Population


How is Per Capita Income Calculated?

All forms of income received by citizens of a nation are included in this total income, including salaries, wages, profits, and any additional revenue from outside the nation, such as remittances and overseas investments. In a similar vein, every citizen of a nation, regardless of nationality or legal status, is included in the total population. The total population includes both non-citizens and citizens of the specific place who have lived in a country for a long time. Every year, the per capita income is usually computed and expressed in a certain currency, such as rupees. 

Illustration:

Imagine a situation when there are ten persons in a room. They all work for a major international corporation and are paid employees. They do, however, earn different salaries and have different areas of expertise. Let's say the pay is as follows: Rs 1 lakh, Rs 1.2 lakh, Rs 2 lakh, Rs 80,000, Rs 1.2 lakh, Rs 2 lakh, Rs 1 lakh, Rs 1.8 lakh, Rs 1.5 lakh, Rs 1.5 lakh. You can see that there is a range of wages. The group's revenue may be easier to understand if you look at the per capita income. The per capita income for this category is ₹1.4 lakh.

Let's make a few minor changes to the example. Let's say there are four unemployed individuals among the 14 people in attendance. Per capita income, thus, is now equal to ₹14 lakh/14, or ₹1 lakh. There are going to be unemployed people in every country. As such, when calculating the per capita income, it is imperative to take into consideration every member of the population.


Conclusion

In conclusion, per capita income by nation is a crucial economic measure that helps determine the state of the economy and emphasises the need for particular care. Policymakers, businesspeople, and investors must make well-informed decisions that will affect the nation's future expansion and development.


FAQ

Q1. What is the per capita income of India?

India's per capita Net National Income (NNI), at constant (2011–12) prices, climbed by 35.12 percent from Rs. 72,805 in 2014–15 to Rs. 98,374 in 2022–23, according to the most recent tentative estimate released on May 31, 2023.


Q2. What was real per capita income?

A nation's economic health is gauged by its real income per capita, which accounts for the purchasing power of its people. It is computed by dividing the GDP (gross domestic product) of the nation by the total population, and then factoring in inflation.


Q3. What are the factors affecting per capita income?

Numerous factors influence per capita income, such as the population's level of education and skill, the state of the infrastructure, the degree of economic development, and the composition of the economy.


Q4. What is the difference between national income and per capita income?

In contrast to national income, which is determined by adding the total of all private, public, and government sectors, national income is the total worth of a nation's ultimate production of all new goods and services generated in a specific year. Total income ÷ population equals per capita income. The entire consumption of a nation's population over a specific time period, such as a year, is calculated to determine per capita consumption.


Q5. How does per capita income differ from other measures of economic well-being?

Per capita income measures the average income earned per person in a given area over a specified period, providing insights into the economic prosperity of the population. Unlike gross domestic product (GDP), which represents the total economic output of a country, per capita income accounts for population size, offering a more nuanced view of individual wealth. It helps assess the distribution of income within a society and serves as a key indicator of living standards and purchasing power.


Q6. What factors contribute to variations in per capita income among different regions or countries?

Variations in per capita income among regions or countries stem from a myriad of factors, including disparities in economic development, resource endowment, educational attainment, infrastructure, and government policies. Developed nations often exhibit higher per capita income due to advanced technology, industrialization, and access to capital, while developing nations may face challenges such as poverty, unemployment, and inadequate healthcare and education systems, resulting in lower per capita income.


Q7. Can per capita income alone provide a comprehensive understanding of economic prosperity within a population?

While per capita income offers valuable insights into individual wealth and standard of living, it has limitations in capturing the full spectrum of economic prosperity. Other factors such as income inequality, cost of living, social welfare programs, and access to essential services like healthcare and education also influence overall well-being. Therefore, policymakers and economists often complement per capita income analysis with additional indicators to gain a more comprehensive understanding of economic conditions and formulate effective policy interventions.


Q8. How does per capita income impact consumer behavior and purchasing power in a given society?

Per capita income directly influences consumer behavior and purchasing power within a society. Higher per capita income generally corresponds to increased discretionary income, enabling individuals to afford a wider range of goods and services. As per capita income rises, consumer demand for luxury items, leisure activities, and non-essential goods tends to increase, driving economic growth and expansion of markets. Conversely, lower per capita income restricts purchasing power, leading to higher levels of saving and reduced consumption, which can hinder economic development and prosperity.


Q9. What are the limitations of using per capita income as a sole indicator of individual wealth and standard of living?

While per capita income provides valuable insights, it has limitations as a sole indicator of individual wealth and standard of living. It does not account for income distribution within a population, overlooking disparities and inequalities that may exist. Additionally, per capita income fails to consider non-monetary factors such as access to healthcare, education, housing, and social services, which are crucial determinants of overall well-being. Therefore, policymakers and researchers often use supplementary measures like the Human Development Index (HDI) or the Gini coefficient to complement per capita income analysis and obtain a more holistic view of societal welfare.


Q10. What distinguishes average income from per capita income? 

Per capita income is the average income per person in a certain location (city, region, country, etc.) for a given year. It is calculated by dividing the region's total revenue by the number of inhabitants. The average income is a statistic that represents the wages of a household, family, or person.


Q11. What does per capita income indicate? 

The amount of money earned per person in a country or geographic area is known as its per capita income. The average per-person income for a certain area is calculated using per capita income, which is also used to assess the population's standard of living and quality of life.


Q12. What does a low per capita income signify?

In general, low per capita income refers to a poorer standard of living and lower average income of residents in a nation or a particular geographic area.


Q13. What could be the causes of the decrease in per capita income?

The low per capita income of the nation is caused by citizens' lower income levels, which are lowered by a lack of access to healthcare, education, and work possibilities.
