4. Oklahoma City

While New England and Florida hold the largest concentration of 55 and better workers, a few cities in the Midwest and West Coast have seen an increase. Oklahoma City, OK saw a 1.5% bump in 55+ workers from 2001 to 2016. Many Oklahomans stay put after retiring, as their nest eggs go further thanks to low housing and energy expenses. The low cost of living brings many from out of state as well, and they may find work in the city’s thriving energy, finance, and distribution industries. The nearby town of Norman even has a 55+ community, the 58-home Fiddler's Green. Farther west in Sacramento, there also was a modest increase in their 55+ workforces.

If you’re looking to work in a major city, Philadelphia, Miami, and New York City have the largest share of 55+ workers of the ten most populous cities. While not the quietest places to retire, these places do attract Millennial workers as well, assuring healthy economies when their more experienced workers enter full-time retirement.

“Whether they are motivated by financial reasons or personal choice, people are staying in the workforce longer,” said Matt Ferguson, CEO of CareerBuilder and co-author of The Talent Equation. “At some point those workers and their intellectual capital will retire, so a city with a workforce that is aging at a faster rate needs to ensure it is attracting an adequate supply of new talent to fill the gap and fuel economic growth. While big cities have broad appeal, younger generations are also gravitating toward second tier markets with diverse economies, a strong technology presence and affordable cost of living.”
