Gross domestic product
Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a period of time, often annually 
GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing differences in living standards between nations.
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.
