The Civilian Conservation Corps (CCC) was a voluntary government work relief program that ran from 1933 to 1942 in the United States for unemployed, unmarried men ages 18–25 and eventually expanded to ages 17–28. The CCC was a major part of President Franklin D. Roosevelt's New Deal that supplied manual labor jobs related to the conservation and development of natural resources in rural lands owned by federal, state, and local governments. The CCC was designed to supply jobs for young men and to relieve families who had difficulty finding jobs during the Great Depression in the United States. There was eventually a smaller counterpart program for unemployed women called the She-She-She Camps, which were championed by Eleanor Roosevelt.

Unemployment, according to the OECD, is people above a specified age not being in paid employment or self-employment but currently available for work during the reference period.
