What is GDP, and what does it leave out?

Gross domestic product, or GDP, is the main way the United States measures its economy and its growth. The Bureau of Economic Analysis defines it as the total market value of the final goods and services produced within the country in a year. Goods are things people make, grow or extract, and services are actions done for someone else. Market value means what something costs in the marketplace. GDP leaves out unpaid household work, volunteer work, illegal activity, and many things that affect well-being but are not bought and sold.

The BEA describes a four-part formula: consumption plus investment plus government spending plus net exports. Consumption is what people spend on groceries, clothing, phone service and health care. Investment is business spending on land, buildings, equipment and unsold inventory, and it also includes consumers' purchases of homes. Government spending covers things like schools, roads and defense. Net exports are exports minus imports. Imports are subtracted because consumers, businesses and governments spend some money on foreign goods, and U.S. production would be overstated otherwise. [1]

Unpaid work people do for themselves and their families is not traded in a market, so there are no transactions to track. The BEA says time-use surveys can estimate it, but the United States only began collecting such data annually in 2003 and many countries have never run a nationally representative survey. That lack of data influenced the decision to exclude household production from the international accounting guidelines. [bea.gov](https://www.bea.gov/help/faq/1297) [2]

An IMF article describes this as a "production boundary" drawn by judgment. Home-produced goods such as food were included, but home-provided services such as cleaning and child care were not. The article says feminist scholars have long objected that work done mainly by women goes unvalued, while many economists agreed in principle but cited the practical difficulty of surveying household services. It argues that as more women work for pay and households switch between buying and doing these services, there is no logical reason to treat household work differently. Demos gives an example: hiring childcare counts in GDP, but a parent caring for their own child does not.

GDP records mostly monetary transactions at market prices. The IMF article notes that it excludes environmental externalities such as pollution, since nobody pays a price for them, and does not net off the depletion of resources or loss of biodiversity. It also ignores capital assets such as infrastructure and human capital, which makes it a short-term measure. Demos adds that the value of natural capital and ecosystems is not reflected.

The OpenStax economics textbook stresses that standard of living is broader than GDP. GDP does not capture leisure time, so a country with longer working hours can show higher output without being better off. It counts spending on health, education and pollution control but not outcomes such as life expectancy, literacy or cleaner air. GDP per capita is an average and says nothing about inequality, product variety, or which technologies exist.
