Economix blogs about projected changes to the share of the working-age population participating in the labor force.

The [Congressional Budget Office] report observes that the participation rate peaked at about 67 percent during the late 1990s and in 2000, since that’s when baby boomers were in their prime working-age years of 25 to 54. Women had also been entering the labor force at a rapid clip.

But since then the share of women who choose to work has fallen. In fact, it’s now at the lowest level in nearly 20 years. Meanwhile baby boomers are reaching retirement age and dropping out of the labor force. Additionally, the share of people under age 25 who are working or looking for work has also fallen.
