This line chart tracks the share of U.S. GDP contributed by three sectors-Federal Government (black), Households (red), and Nonfinancial Businesses (blue)-from 1920 to 2010. The Federal Government’s share spiked sharply during WWII (peaking near 1.1 around 1945), then declined steadily until the 1980s before stabilizing. Households and Nonfinancial Businesses exhibit more gradual growth, with notable dips during the Great Depression and 2008 financial crisis, and convergence after 1960.
