Personal income is an individual's total earnings from wages, investment interest, and other sources. In the United States the most widely cited personal income statistics are the Bureau of Economic Analysis's personal income and the Census Bureau's per capita money income. The two statistics spring from different traditions of measurement—personal income from national economic accounts and money income from household surveys. BEA's statistics relate personal income to measures of production, including GDP, and is considered an indicator of consumer spending. Census's statistics provide detail on income distribution and demographics and are used to produce the nation's official poverty statistics. Inflation-adjusted ("real") per-capita disposable personal income rose steadily in the U.S. from 1945 to 2008, but has since remained generally level.
