Terms and definitions: GDP (gross domestic product): it represents the sum of all final products and services produced by all permanent units in a certain period of time in a country (or region), and is usually considered as an indicator to measure the economic situation of the country (or region).
Per capita GDP: Comparing the GDP in a national accounting cycle (usually one year) with the permanent population (or registered population) of this country, the result is not only per capita GDP, but also a standard to measure the living standards of people in various countries. In order to measure it more objectively, it is often combined with purchasing power parity.
