Population Distribution by Age in 5-year increments for Tampa-St Pete-Clearwater. Interesting that the peak years in the boom is the 45-to-50 year olds. The 45-55 block in this demographic will see benefits reduced or the retirement age extended for Medicare and Social Security (or both). Will housing prices rebound by retirement age for this block of middle-aged boomers? Will there be a market for single family homes, then, allowing these late-boomers to cash out?
