About three-quarters of wealthy U.S. baby boomers (search) who are still at work do not plan to fully retire when they reach their chosen retirement age, according to a poll released on Wednesday.

The survey showed 34 percent of this affluent group intend to work a reduced schedule after retirement age, 30 percent plan to start a new career, and 10 percent do not expect to retire at all.

Further, 63 percent of affluent, non-retired baby boomers intend to fund their eventual retirement by selling their primary residence, according to the report.

Chicago-based consultants Spectrem Group (search) polled 500 baby boomers with $500,000 or more in assets to invest. Baby boomers are defined as individuals born between 1946 and 1964.

"Affluent baby boomers in large numbers are saying 'no' to the concept of traditional retirement -- opting to remain in the workforce when they hit their chosen retirement age," said George Walper, president of Spectrem Group.

"This coincides, of course, with significant uncertainty about social security and the elimination of so many traditional retirement plans," added Walper.

The fact that such a high percentage of these individuals plan to sell their homes to finance their eventual retirement suggests that few will have the type of 'golden years' retirement their parents enjoyed, Walper said.

Spectrem said baby boomers represent nearly half of the 190 million U.S. workers fully insured for social security, citing U.S. Census Bureau (search) statistics.

The first baby boomers will turn 65, the current standard retirement age, in 2011, Spectrem said. About 69 percent of all baby boomers are still at work.

Spectrem said the poll showed that expectations of affluent baby boomers "are substantially different from the experience of current retirees."

About 62 percent of current retirees were fully retired at their chosen retirement age, the report found. This compares to the 26 percent of affluent, working baby boomers expecting to do so.
