"Gross domestic product (GDP) per capita is an economic indicator used to express the value of the total goods and services produced by a country or region within a certain period of time, and then divided by the population of the country or region to obtain economic value created.

GDP per capita is an important economic indicator because it can be used to compare the level of economic development of different countries or regions. The higher the per capita GDP of a country means that the people in that country have more economic resources and a higher standard of living on average. Conversely, countries with low per capita GDP may face problems such as poverty and economic backwardness.

GDP per capita can also be used to measure the economic growth rate of a country or region. If the per capita GDP of a country or region continues to grow, it means that the economy of the country or region is in a stage of healthy development. Conversely, if GDP per capita continues to decline, it may mean that the country or region is facing economic recession or other challenges.

GDP per capita is calculated by dividing the total GDP of a country or region by the population of that country or region. For example, if a country's total GDP is $1 trillion and the country's population is 100 million people, then the country's GDP per capita is $10,000. The calculation of per capita GDP can help us understand the level of economic development of a country or region, and provide basic data for the government and enterprises to formulate appropriate development strategies and policies.
