Why do people live in cities? Well, obviously, there are a lot of reasons, from work opportunities to cultural amenities. But for our purposes, one of the reasons is independence. Unlike rural or suburban locations where movement is largely dependent on owning a car, people who live in cities have so many more options for getting about, thanks to dense, walkable neighborhoods and extensive public transit.
Independence is a key reason why people tend to enjoy aging in cities, too. This desire has led, in part, to a growing trend whereby seniors cluster together in cities. These clusters, first noted in 1986 by University of Wisconsin-Madison professor Michael Hunt, are called naturally occurring retirement communities. NORCs, as they are known, aren't purposely built for seniors. Rather, they evolve naturally, as adult residents age in place.
