GDP, only available as annual averages, plunged 25.6 percent from 1929-1932, including by 13.0 percent in 1932. It stabilized in 1933, and then soared by 10.8 percent, 8.9 percent and 12.0 percent, respectively, in 1934, 1935 and 1936. Real GDP surpassed its 1929 peak in 1936 and never again fell below it. After-tax personal income, consumer spending, real private investment and jobs all reached or surpassed their 1929 peaks by late 1936.
