Tens of thousands of retirees are pulling up stakes in suburban areas and fashioning their own retirement communities in the heart of the bustling city. They are looking for what most older people want: a home with no stairs and low crime rates. And they are willing to exchange regular weekly golf time for rich cultural offerings, young neighbors and plenty of good restaurants. Spying an opportunity, major real-estate developers have broken ground on urban sites they intended to market to suburban retirees. These seniors are already changing the face of big cities. One developer, Fran McCarthy asks: “Who ever thought that suburban flight would be round trip?”

The trickle of older folks returning to the city has grown into a steady stream. While some cities, especially those with few cultural offerings, have seen an exodus of seniors, urban planners say others have become retirees magnets. Between 1999 and 2000, the population of 64-to-75-year-olds in downtown Chicago rose 17 percent. Austin, New Orleans, and Los Angeles have seen double-digit increases as well. There may be hidden health benefits to city living. A study reveals that moving from suburbs to the city can ward off the byproduct of aging---social isolation. In the next six years, downtowns are expected to grow even grayer. For affluent retirees, city life is an increasingly popular option.
