List of countries by GDP (nominal)
Gross domestic product (GDP) is the market value of all final goods and services from a nation in a given year. Countries are sorted by nominal GDP estimates from financial and statistical institutions, which are calculated at market or government official exchange rates. Nominal GDP does not take into account differences in the cost of living in different countries, and the results can vary greatly from one year to another based on fluctuations in the exchange rates of the country's currency. Such fluctuations may change a country's ranking from one year to the next, even though they often make little or no difference in the standard of living of its population.
Valuation of Nonmarket Housework
The GPI is an alternative to GDP as a measure of economic growth that is generally designed to incorporate environmental and social factors that are not traditionally included. While much of the focus is typically placed on environmental costs, most GPI measurements explicitly include additions for the value of household work and parenting.
