It was the longest, most severe depression ever experienced by the industrialized western world. Although it originated in the United states, it still effected almost every country in the world, like severe unemployment. The depression was long and severe in the united states, and Europe, it was milder in Japan and Latin America. The great depression began in the united states as an ordinary recession in the summer of 1929. The downturn became markedly worse, however, in late 1929 it continued until early 1933. Between the peak and through of the downturn, industrial production in the united states declined 47% and real GDP (gross domestic product) fell 30%, the wholesale price index declined 33%. It is widely agreed that the unemployment rate exceeded 20% at its highest point. The depression affected virtually every country of the world. However the dates and magnitude of the downturn varied across countries. GB struggled with low growth and recession during the most of the second half of the 1920s. Britain did not slip into severe depression, However until early 1930 and its peak to through decline in industrial production was roughly one-third that of the united states, France also experienced a short downturn in 1930s. France 1933-1936. Germany 1928 then stabilized before turning down again in 3'd quarter 1929. Latin America later 1928- early 1929. While some less developed countries experienced severe depressions, such as Argentina and Brasil, experienced comparatively mild downturns. Japan had a mild depression, which began late but ended early.
