Where have all the missing American workers gone?

WASHINGTON (AP) — The unemployment rate has been on a slow downward trajectory since the recession ended nearly five years ago. While the overall jobless level has dropped to non-recession levels, the number of the working-age people with jobs is barely over 6 in 10, hovering at a level reminiscent of the late 1970s.

In May, the U.S. workforce-participation rate — the combination of those with jobs and unemployed workers actively seeking them — was just 62.8 percent, the same as the month before. Job markets have been essentially flat since October.
