US Bureau of Labor Statistics:

The nation’s civilian noninstitutional population, consisting of all people 16 or older who were not in the military or an institution, reached 251,096,000. Of those, 157,065,000 participated in the labor force by either holding a job or actively seeking one.

The 157,065,000 who participated in the labor force equaled only 62.6 percent of the 251,096,000 civilian noninstitutional population — the same as it was in July and June. Not since October 1977, when the participation rate dropped to 62.4, has the percentage been this low.
