In general, mothers with older children (6 to 17 years of age) are more likely to participate in the labor force than are mothers of younger children (under 6 years of age).
The labor force participation rate of mothers with older children rose from 55 to 79 percent during the last quarter of the 20th century, before declining to 77 percent by 2005. The rate for mothers with younger children has ranged from 39 to 65 over the last three decades, peaking in 2000.
