Gross Domestic Product (GDP) refers to the total value of all goods and services produced inside a country's borders over a certain period of time. Gross domestic product (GDP) is a widely used metric that quantifies the economic well-being of a nation and serves as a gauge of its overall quality of life. Furthermore, GDP serves as a means to assess and contrast the levels of production across various nations. An eminent benefit of GDP is its consistency in computations across different countries. Therefore, doing a comparison across nations yields a significant degree of precision. Moreover, GDP serves as an indicator of economic development or contraction and the growth or collapse of an economy. The World Bank, the United Nations, and the International Monetary Fund are among the several organisations that gather and provide statistics about GDP estimates across all nations.

Nominal GDP Gross Domestic Product (GDP) measured at current prices, without adjusting for inflation is Nominal GDP. Nominal GDP refers to the measurement of GDP using the current market prices. Nominal GDP is not adjusted for inflation, it is probable that the statistics provided are greater than the estimates for real GDP.

Gross Domestic Product per Capita (Purchasing Power Parity) GDP per capita is a metric that quantifies the overall economic production of a nation. It is computed by dividing the country's GDP for a certain time, often one year, by the average total population during that period. Per capita GDP is often used as a metric to gauge living standards and the efficiency of a nation's labour force. GDP per capita, calculated using purchasing power parity (PPP), is estimated by PPP calculations. Purchasing Power Parity (PPP) enables the comparison of the quality of life and earnings across various nations, while accounting for variations in price levels within each country.

Gross Domestic Product (GDP) per Hour Worked Gross Domestic Product (GDP) per hour worked serves as a measure of a nation's labour productivity. It quantifies the degree of efficiency in which labour is integrated with other components and used in the process of production. Gross Domestic Product (GDP) per hour worked is determined by dividing the actual output by the total number of hours worked, which serves as a measure of labour input.
