Changes in labor force participation varied by age group. The biggest increase in labor force participation was among those age 25 to 34—their rate more than doubled, from a level of 34.0 percent in 1950 to 76.3 percent in 1998. Also, in 1950 women age 16 to 24 had the highest labor force participation rate (43.9 percent); in 1998 women age 35 to 44 had the highest rate (77.1 percent), followed closely by those age 25 to 34 (76.3 percent) and those age 45 to 54 (76.1 percent).

The only age group to experience a decline in labor force participation between 1950 and 1998 was those age 65 and over. The rate for women in this age group dropped from 9.7 percent to 8.6 percent.
