Gross Domestic Product (GDP): GDP is the total value of goods and services produced within a country's borders over a specific period. It does not directly measure human development but can be an indicator of economic growth.
Life Expectancy: Life expectancy refers to the average number of years a person is expected to live in a particular country. It is one component used in calculating the HDI.
Education Attainment: Education attainment measures the average number of years individuals have spent in school or received formal education. This factor also contributes to the calculation of the HDI.
