The average U.S. resident who will become eligible for retirement in 2008 is relatively prosperous.

Researchers at the MetLife Mature Market Institute, an arm of a unit of MetLife Inc., New York, have reported that finding in a summary of results from a recent telephone survey of 1,000 U.S. residents who were 61 in 2007.

The survey participants are the oldest baby boomers, or members of the generation born from 1946 to 1964.

The average member of the 1946 birth group has an annual income of $71,400, a home with a value of $297,900, and household net worth, excluding home value, of $257,800, the institute researchers say.

The average member of the group plans to be fully retired by age 66 years 4 months but does not expect to be old till he or she is age 77 years and 10 months.

The oldest boomers do not have financial advisors and do not plan to use reverse mortgages, and, unless they already own stocks, bonds, annuities or long term care insurance, they have few plans to buy those products in the next 12 months, researchers say.
