Crime has dropped in the inner city. Where did it go to?

About five years ago, Janikowski embarked on a more ambitious project. He’d built up enough trust with the police to get them to send him daily crime and arrest reports, including addresses and types of crime. He began mapping all violent and property crimes, block by block, across the city. “These cops on the streets were saying that crime patterns are changing,” he said, so he wanted to look into it.

When his map was complete, a clear if strangely shaped pattern emerged: Wait a minute, he recalled thinking. I see this bunny rabbit coming up. People are going to accuse me of being on shrooms! The inner city, where crime used to be concentrated, was now clean. But everywhere else looked much worse: arrests had skyrocketed along two corridors north and west of the central city (the bunny rabbit’s ears) and along one in the southeast (the tail). Hot spots had proliferated since the mid-1990s, and little islands of crime had sprung up where none had existed before, dotting the map all around the city.

Janikowski might not have managed to pinpoint the cause of this pattern if he hadn’t been married to Phyllis Betts, a housing expert at the University of Memphis. Betts and Janikowski have two dogs, three cats, and no kids; they both tend to bring their work home with them. Betts had been evaluating the impact of one of the city government’s most ambitious initiatives: the demolition of the city’s public-housing projects, as part of a nationwide experiment to free the poor from the destructive effects of concentrated poverty. Memphis demolished its first project in 1997. The city gave former residents federal “Section8” rent-subsidy vouchers and encouraged them to move out to new neighborhoods. Two more waves of demolition followed over the next nine years, dispersing tens of thousands of poor people into the wider metro community.

If police departments are usually stingy with their information, housing departments are even more so. Getting addresses of Section 8 holders is difficult, because the departments want to protect the residents’ privacy. Betts, however, helps the city track where the former residents of public housing have moved. Over time, she and Janikowski realized that they were doing their fieldwork in the same neighborhoods.

About six months ago, they decided to put a hunch to the test. Janikowski merged his computer map of crime patterns with Betts’s map of Section8 rentals. Where Janikowski saw a bunny rabbit, Betts saw a sideways horseshoe (“He has a better imagination,” she said). Otherwise, the match was near-perfect. On the merged map, dense violent-crime areas are shaded dark blue, and Section8 addresses are represented by little red dots. All of the dark-blue areas are covered in little red dots, like bursts of gunfire. The rest of the city has almost no dots.

Betts remembers her discomfort as she looked at the map. The couple had been musing about the connection for months, but they were amazed—and deflated—to see how perfectly the two data sets fit together. She knew right away that this would be a “hard thing to say or write.” Nobody in the antipoverty community and nobody in city leadership was going to welcome the news that the noble experiment that they’d been engaged in for the past decade had been bringing the city down, in ways they’d never expected. But the connection was too obvious to ignore, and Betts and Janikowski figured that the same thing must be happening all around the country. Eventually, they thought, they’d find other researchers who connected the dots the way they had, and then maybe they could get city leaders, and even national leaders, to listen.

But who wants to listen? To listen is to accept there is a problem.
