Unemployment is one of the biggest causes of poverty in the United States. Prolonged periods of unemployment can push households into debt and increase rates of relative poverty. Loss of income can leave people without sufficient income to meet housing costs. Rises in unemployment often exacerbate the rates of homelessness.Those who are unemployed will find it more difficult to get work in the future (this is known as the hysteresis effect). Amongst studies of unemployed men, signs of depression, mental anxiety, and health problems are noticeably higher.
