Apparently, a life of leisure is not all it’s cracked up to be. Or working until age 65 is simply not enough to keep the retirement account going until the end.

Whether through desire or necessity, more older workers are staying in their jobs longer or returning after retiring, according to data from the Bureau of Labor Statistics.

According to the bureau, the number of employed people who were 65 and older doubled from 1977 to 2007, compared with a 59 percent increase for those 16 and older.

This increase is not explained by any skewing effect of the baby-boom population — those born between 1946 and 1964 — because no baby boomers have even turned 65 yet.

There has also been a shift in the number of older workers who work full time versus part time. “As a result, full-timers now account for a majority among older workers: 56 percent in 2007, up from 44 percent in 1995,” the bureau notes.
