After Armistice Day, short depression in the United States was accompanied by a rise in production. Nevertheless, the 1920 depression was also caused by the post-war changes, especially the demobilization of troops.
The reintegration of soldiers into the civilian labor force was one of the main changes. There were 2.9 million people working in the Military in 1918. This declined in 1919 to 1.5 million and in 1920 to 380,000.
It was 1920 when civilian labour rose by 1.6 million or 4.1 percent in one year, and the effects on the labor markets were most startling. (This is the highest one-year rise in labor force, although it is lower than the figures during the sub-World War II demobilization in 1946 and 1947)
