"The unemployment rate doesn’t tell the full story, however. Government statistics count people as unemployed only if they are looking for work, a definition that excludes people who are voluntarily or involuntarily out of the labor force entirely. During the recession and recovery, that distinction was crucial: The official unemployment rate ignored millions of people who had abandoned their job searches as hopeless. Eight years of job growth, however, have shrunk the pool of “discouraged” workers, and broader definitions of unemployment all show strong progress."
