ebri.org Notes, April, 2014
The labor-force participation rate for those ages 55 and older rose throughout the 1990s and into the 2000s, when it began to level off but with a small increase following the 2007–2008 economic downturn.
For those ages 55–64, the upward trend was driven almost exclusively by the increased labor-force participation of women, whereas the male participation rate was flat to declining. However, among those ages 65 or older,
the rate increased for both males and females over that period.
