Per capita income (PCI) or average income measures the average income earned per person in a given area (city, region, country, etc.) in a specified year. It is calculated by dividing the area's total income by its total population. [1] [2]

Per capita income—a nation's growth

Per capita income is national income divided by population size. Per capita income is often used to measure a sector's average income and compare the wealth of different populations. Per capita income is often used to measure a country's standard of living. It is usually expressed in terms of a commonly used international currency such as the euro or United States dollar, and is useful because it is widely known, is easily calculable from readily available gross domestic product (GDP) and population estimates, and produces a useful statistic for comparison of wealth between sovereign territories. This helps to ascertain a country's development status. It is one of the three measures for calculating the Human Development Index of a country.

Euro Currency of most countries in the European Union

The Euro is the official currency of 19 of the 28 member states of the European Union. This group of states is known as the eurozone or euro area, and counts about 343 million citizens as of 2019. The euro, which is divided into 100 cents, is the second-largest and second-most traded currency in the foreign exchange market after the United States dollar.

United States dollar Currency of the United States of America

The United States dollar is the official currency of the United States and its territories per the Coinage Act of 1792. The act created a decimal currency by creating the following coins: tenth dollar, one-twentieth dollar, one-hundredth dollar. In addition the act created the dollar, half dollar, and quarter dollar coins. All of these coins are still minted in 2019.

Gross domestic product market value of goods and services produced within a country

Gross domestic products (GDP) is a monetary measure of the market value of all the final goods and services produced in a specific time period, often annually. GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing living standards between nations, while Nominal GDP is more useful comparing national economies on the international market.

United States

In the United States, it is defined by the U.S. Census Bureau as the following: "Per capita income is the mean money income received in the past 12 months computed for every man, woman, and child in a geographic area." [3] (Individuals who are at least 15 years old are counted.)

Critics

Critics claim that per capita income has several weaknesses in measuring prosperity: [4]

Inflation Increase in the general price level of goods and services in an economy over a period of time

In economics, inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index, usually the consumer price index, over time.

Purchasing power parity (PPP) is a theory that measures prices at different locations using a common good or goods to contrast the real purchasing power between different currencies. In that case, PPP produces an exchange rate that equals the price of the basket of goods at one location over the price of the basket of goods at a different location. The PPP exchange rate may be different than the market exchange rate because of transportation costs, tariffs, and other frictions. PPP exchange rates are widely used when comparing GDP from different countries.

There are several kinds of means in various branches of mathematics.

Total personal income is defined by the United States' Bureau of Economic Analysis as:

income received by persons from all sources. It includes income received from participation in production as well as from government and business transfer payments. It is the sum of compensation of employees (received), supplements to wages and salaries, proprietors' income with inventory valuation adjustment (IVA) and capital consumption adjustment (CCAdj), rental income of persons with CCAdj, personal income receipts on assets, and personal current transfer receipts, less contributions for government social insurance.

The U.S. is not counted as a whole in the overall rank because this would be double counting since the states of the U.S. are being compared to other countries. These figures are calculated using exchange rate conversions, and exchange rates fluctuate from year to year.
