The CONGRESSIONAL BUDGET OFFICE Tells it like it is.

In an August 2016 update to the nation's budget and economic outlook, the Congressional Budget Office said the "prevailing decline" in the labor force participation rate "reflects underlying demographic trends and, to a smaller degree, federal policies."
The CBO said factors contributing to the decline in labor force participation include the continued retirement of baby boomers, reduced participation by less-skilled workers, and the lingering effects of the recession and weak recovery.
"In addition," the report said, "certain aspects of federal laws, including provisions of the Affordable Care Act and the structure of the tax code, will reduce participation in the labor force by reducing people’s incentive to work or seek work."
The labor force participation rate is the percentage of people in the civilian noninstitutionalized population, age 16 or older, who are either working or actively seeking work. People who are no longer looking for work, for whatever reason -- retirement, school, family, or they've just given up -- are not participating in the labor force.
In Friday’s report, BLS said the economy added 156,000 jobs in September, below analysts' expectations of about 175,000.
So far this year, job growth has averaged 178,000 per month, compared with an average of 229,000 per month in 2015. In September, employment gains occurred in professional and business services and in health care.
The September unemployment rate increased a tenth of a point to 5.0 percent, as the number of unemployed persons increased 90,000 to 7,939,000 -- and the number of employed persons increased 354,000 to 151,968,000.
The labor force participation rate started rising in the early 1970s as more women entered the labor force. It reached a record high of 67.3 percent, seasonally adjusted, in the beginning of 2000. And it dropped to a 38-year low of 62.4 percent in September 2015. Since then, it has never gone higher than 63.0 percent.
Yellen told Congress last month that the participation rate is feeling "significant downward pressure" from the aging of the population, as more and more Baby Boomers retire and leave the labor force.
"Aging of the population maybe one factor," Rep. Andy Barr (R-Ky.) told Yellen at the hearing of the House Financial Services Committee. "The other factor is that unemployment is coming down, not for a good reason, but for the wrong reason -- namely, that there's a frustrated workforce out there that's completely given up looking for work."

In September, the nation’s civilian noninstitutionalized population, consisting of all people 16 or older who were not in the military or an institution, reached 254,091,000. Of those, 159,907,000 participated in the labor force by either holding a job or actively seeking one.
The 159,907,000 who participated in the labor force equaled 62.9 percent of the 254,091,000 civilian noninstitutionalized population.
Among the major worker groups, the unemployment rate for Hispanics increased to 6.4 percent in September.
The rates for adult men (4.7 percent), adult women (4.4 percent), teenagers (15.8 percent), Whites (4.4 percent), Blacks (8.3 percent), and Asians (3.9 percent) showed little or no change.
