United States: historical total unemployment and unemployment rate 1890-1988

From the late 19^th century until the 1980s, the United States' unemployment rate was generally somewhere between three and ten percent of the total workforce. The periods when it peaked were in times of recession or depression - the Panic of 1893, which lasted until 1897, saw unemployment peak at over 18 percent, whereas the post-WWI recession saw unemployment spike to almost 12 percent in 1921.

However, the longest and most-severe period of mass unemployment in U.S. history came during the Great Depression - unemployment rose from just 3.2 percent in 1929 to one quarter of the total workforce in 1933, and it was not until the Second World War until it fell below five percent once more. Since this time, unemployment has never exceeded 10 percent, although it did come close during the recessions of the 1970s and 1980s.
