The great depression was unusual because it was so deep and lasted so long. in fact, it was actually two separate recessions (august 1929 to march 1933, and may 1937 to june 1938). the great depression was also characterized by another striking condition: prices across the economy declined throughout the course of the decade. in fact, at the end of the 1930s, the general price level, as measured by the gdp deflator, was 20% lower than it had been in 1929.

See the explanation below.
