Late last year, 5Pointz a graffiti hotspot in Queens, New York, was whitewashed, erasing years of graffiti by artists from all over the world. Since the ’90s, street artists have been allowed to spray paint the walls of the warehouse in Long Island City, and the work that appears has long been curated by the graffiti artist Meres, whose goal was to turn the industrial space into a graffiti museum. More recently, the building’s owner, Jerry Wolkoff, forged ahead with plans to tear the warehouse down and turn the property into high-rise apartment buildings, starting by painting over the existing graffiti.

“It’s a little surprising, in this day and age, in this city, that the property owner there didn’t recognize the cultural value–that kind of implies economic value–in something as famous and hip as 5Pointz,” sociologist Gordon Douglas told Co.Design. Despite its bad rap as a sign of disorder–and criminal status–graffiti has become more than just a public nuisance. In some cases, it can be a positive economic force for a city.

“A huge amount of social science throws [graffiti] into a camp of being a sign of crime and disorder,” Douglas, a Ph.D. candidate at the University of Chicago, says. “The truth is, at this point, some graffiti and street art are arguably contributing to gentrification and contributing to increases in the appeal of certain neighborhoods.”

Scholars question whether we should consider graffiti criminal if it’s a Banksy piece worth $100,000.

In SoHo, Baruch College sociologist Gregory Snyder writes in his book Graffiti Lives, “residents, tourists, and high-end boutiques, co-exist with graffiti vandalism in a relatively symbiotic fashion.” Snyder compared rates of graffiti and violent crime in different neighborhoods in New York City, and found higher concentrations of graffiti in places like SoHo, which have fairly low rates of violent crime. The heavily tagged neighborhood “attracts the type of urban ‘cool’ consumer that marketers call ‘taste makers’ and that advertisers and retailers so desperately want to reach,” he writes.

Graffiti-hunting has become a sort of tourism. People visit East London or New York’s Lower East Side and Williamsburg or, formerly, 5Pointz, just to see some of the graffiti there. “Some scholars have questioned whether we should consider graffiti criminal damage if in fact, it’s a Banksy piece that’s worth $100,000–if you can somehow get it off the wall,” Douglas says.

Economist Elizabeth Currid-Halkett, an associate professor at the University of Southern California, says there’s a strong relationship between the cultural activity of a city–which graffiti is a part of–and its economy. “When you see graffiti, it’s really a sign of many more interesting creative things going on,” she told Co.Design. Cities that have more graffiti tend to be cultural and artistic hubs.

And street art tends to give people who don’t have the resources to launch a more traditional art career a shot. “Historically, graffiti artists were kids from poor neighborhoods, working class families, who didn’t have resources, and the city became their canvas,” Currid-Halkett explains. “I think that that’s an important part of the ecology of a city… It allows people who don’t have much to make it.”
