The unemployment rate in the United States before Black Friday and the Great Depression was 3.14% of the active population in 1929. That is to say 1,550,000 million workers without a job for a population of 88,010,000 and a labor force of 49,440,000. In 1930, those figures had already increased to 8.67 %, i.e. 4,340,000 million workers out of a labor force of 50,080,000 and a population of 89,550,000.
