English: Real Gross Domestic Product (GDP) per capita for the United States, 1790 - 2015. The solid vertical lines mark the administrations of Herbert Hoover and Franklin Roosevelt. The dashed red line marks the beginning of World War II. If we divide this into the historical period until 1929, Hoover to 1933, Franklin Roosevelt pre-war to 1939, WW II to 1945, post-war to 2007, and Great Recession to 2016, we find the growth averaged 1.5, -8.1, 6.2, 10.1, 1.9, and 0.5 percent per year in these epochs, respectively. GDP per capita has doubled five times since 1800: The first two were to 1862 and 1900. The gains between 1900 and 1929 were lost by 1933. Since 1933, it has doubled three times: to 1941, 1972, and 2011. For more, check the data from Johnston, Louis; Williamson, Samuel H. (2016) What Was the U.S. GDP Then?^[1], MeasuringWorth.
