The economy showed some signs of life when the Supreme Court struck his "New" Deal down. Unemployment dropped to 18 percent in 1935, 14 percent in 1936, and even lower in 1937.
Then you have the court packing scheme. Unemployment returns to 20 percent by 1938, and the stock market crashes nearly 50 percent.
by the end of his presidency, the numbers were waaay back down. Unemployment jumped only one year, decreased all the others. I don't remember all the exact numbers, but I remember the steady decrease.
