Researchers track the diffusion of crime over time to see what happens when dysfunctional housing projects are at last replaced

As critics have lamented for years, the mega American public housing projects built during the 1960s and ‘70s were often so flawed in their design as to harm residents – and the neighborhoods around them – more than they helped anyone. They were designed on super blocks that cut residents off from the surrounding community and that kept police from easily accessing the grounds. They were built in shoddy barracks and imposing towers, neither of which gave residents any control over the safety of their communal outdoor spaces. They were, in a sense, dangerous by design (although no one thought of it that way at the time).

“There’s this combination of all of these issues serving to perpetuate that stereotype about people who live there, that public housing itself were bad areas, and they were havens for crime,” says Meagan Cahill, a researcher at the Urban Institute. “But in a way, they did become havens for crime. It’s hard for police to police them, you had a lot of low-income people living there, a lot of people who might have been marginalized economically, and not a lot of job opportunity in neighborhoods where the housing was built.”

Eventually, cities started razing a lot of the worst projects, many under the Hope VI federal grant program that offered financing for a new generation of public housing that wasn't supposed to look like public housing at all. Hope VI called for rebuilding mixed-income communities on shorter blocks with less institutional town homes and designing streets, lawns, and porches that people would want to cherish and protect.

It wasn’t clear though what would happen to all that crime when old public-housing fortresses were demolished. Would it move with the residents when they were dispersed? Would it just cross the street? And would any improvements really last over time?

Cahill and several researchers at the Urban Institute have tried to answer these questions in a series of fascinating case studies in Washington, D.C. and Milwaukee, and the results of their research speak to the power of design to potentially alter the course of even crime statistics.

They looked at two of the worst projects in Washington, in the Capper/Carollsburg and Capitol Gateway areas of the city, and a third site on the north side of Milwaukee. All three had been exemplars of the old, flawed public-housing model, and they were all redeveloped under Hope VI over the last decade, on the same sites, into communities that wouldn’t be easily recognized as public housing today. In Washington, the redevelopment took so many years that a mostly new population moved in. In Milwaukee, the residents remained in place throughout the construction and make up a similar group today to the one that lived in the project before.

In both cities, the researchers watched crime fall – at the sites themselves and in the neighborhoods around them.

“I actually honestly was pretty surprised that it was that dramatic,” Cahill says of the results. “I think they are pretty impressive.”

This is what the diffusion of crime looked like over time at the Capper/Carollsburg site:

And this is how it appeared around Capitol Gateway:

The crime, in other words, didn’t just relocate. Much of it disappeared. This process took longer in Milwaukee, but the fact that it eventually happened there, too – when the population of residents largely remained the same – underscores the impact of changing the places themselves. Hope VI didn’t make these projects safer merely by breaking up the concentration of crime that had developed in them.

“I think the biggest thing they did was think about the design of the new places,” Cahill says.

Of course, all of this decline in crime likely can’t be traced back to the renewed housing itself. These areas have seen other redevelopment as well. And Hope VI included other reforms, such as increasing the social services in these communities. But Cahill’s maps are telling, and they raise intriguing questions about exactly how a community changes when its built environment does.

Did these neighborhoods become safer because better housing telegraphed to the residents that their communities were valuable?

“If there is crime in an upscale neighborhood, everybody would come together, people would be up in arms, they’d demand the police pay attention, they’d say ‘let’s get more patrols in here!’” Cahill says. “Low-income residents in a lot of poor areas, they’ve just given up on the police, they’re not treated well by the police. They feel like the problems are too large for them to address. This is returning that sense of power to the residents, increasing the community’s capacity to do something about their situation.”
