Based on a country's gross domestic product (GDP), one can draw the conclusion about how many goods and services it produces in a year. GDP primarily measures the total economic output of a country, reflecting the value of all finished goods and services produced over a specific time period.
While GDP can give indirect insights into purchasing power, quality of life, and life expectancy, it does not directly measure these factors. Countries with similar GDP figures can have significantly different levels of income distribution, quality of life, and life expectancy, depending on other socioeconomic factors.
