Suicide rates in the U.S. tend to rise during recessions and fall amid economic booms, according to study from the Centers for Disease Control and Prevention. Suicides reached a record high of 22 people per 100,000 in 1932 during the Great Depression, CDC officials said in a report published online today in the American Journal of Public Health. That was double the rates seen in 2000, when 10 people per 100,000 took their lives as the economy prospered, the study found. The study is the first to link business cycles and suicide rates among specific age groups, according to the Atlanta-based CDC. People in their “prime working ages” of 25 to 64 years old are the most likely to commit suicide during recessions, the study found.
