The Great Depression was a worldwide economic downturn that began in 1929 and lasted until about 1939. It was the longest and most severe depression ever experienced by the industrialized Western world, sparking fundamental changes in economic institutions, macroeconomic policy, and economic theory. The depression began in the United States when, in a period of ten weeks, stocks on the New York Stock Exchange lost 50 percent of their value. As stocks continued to fall during the early 1930s, businesses failed, and unemployment rose dramatically. By 1932, one of every four workers was unemployed. Banks failed and life savings were lost, leaving many Americans destitute. With no job and no savings, thousands of Americans lost their homes. The poor congregated in cardboard shacks in so-called Hoovervilles on the edges of cities across the nation; hundreds of thousands of the unemployed roamed the country on foot and in boxcars in futile search of jobs. Although few starved, hunger and malnutrition affected many.
The contraction began in the United States and spread around the globe. The timing and severity of the Great Depression varied substantially across countries. The Depression was particularly long and severe in the United States and Europe; it was milder in Japan and other countries. Factories were shut down, farms and homes were lost to foreclosure, mills and mines were abandoned, and people went hungry. The resulting lower incomes meant the further inability of the people to spend or to save their way out of the crisis, thus perpetuating the economic slowdown in a seemingly never-ending cycle. The Great Depression caused drastic declines in output, severe unemployment, and acute deflation in almost every country of the world. Its social and cultural effects were no less staggering, especially in the United States, where the Great Depression represented the harshest adversity faced by Americans since the Civil War.
