The connection between parks and crime continues to be debated.
Some specialists say parks and different city inexperienced areas forestall violence. When vacant tons and deteriorating city areas change into extra engaging and helpful locations for residents, violence and crime usually lower within the speedy neighborhood.
In a research of social housing in Chicago, researchers discovered 52% fewer reported crimes close to buildings surrounded by timber and different forms of vegetation. In New York, neighborhoods that make investments extra in public inexperienced areas common a median of 213 crimes a yr.
Comparable relationships between inexperienced areas and crime have been noticed in Baltimore, Chicago, Philadelphia and Portland, in addition to in cities exterior the USA.
Nonetheless, in lots of cities, individuals think about parks as harmful locations: they appeal to unlawful actions reminiscent of drug trafficking and permit criminals to contact potential victims who, when engaged in leisure actions, could also be much less vigilant about their property and private security.
Analysis additionally helps this concept. A 2015 research of a number of cities in the USA discovered that property crime charges had been two to 4 occasions increased in neighborhoods near parks. Charges of violent crime had been as much as 11 occasions increased.
Do parks make cities safer or extra harmful? The quick reply is: it is dependent upon the park.
Inexperienced areas result in a lower in crime
One of many the explanation why the proof on the park-crime relationship is so heterogeneous is that the majority research on this topic have targeted on one metropolis or place.
So as to establish nationwide tendencies, our analysis workforce from Clemson College and North Carolina College started in 2017 to gather data on crime, inexperienced areas and parks within the 300 largest cities of Canada. United States.
Not like many research that use the phrases "parks" and "inexperienced areas" interchangeably, our evaluation has distinguished these two city environments.
The inexperienced house was measured by the quantity of grass, crops, forest cowl and different inexperienced areas of the panorama. We outlined city parks as designated open areas managed by a public physique – a subset of inexperienced areas.
To tell apart the affect of inexperienced areas from the social elements usually related to crime – inhabitants density, revenue, schooling, variety and social drawback – we took these elements under consideration when evaluating the information on the crime.
We realized that extra greenspace was related to decrease crime threat within the 300 cities we surveyed.
Burglaries, robberies, automobile theft and different property crime are much less frequent within the greener neighborhoods of all cities in our pattern. Violent crimes reminiscent of homicide, assault and armed theft had been additionally much less frequent within the greener neighborhoods of just about each metropolis we studied.
Solely three cities in our pattern didn’t make the most of inexperienced areas. In Chicago, Detroit and Newark – all locations the place the crime charge is notoriously excessive and cussed – extra greenspace was related to increased ranges of violent crime.
Specialists have recognized a number of the explanation why the presence of inexperienced areas can result in a lower in crime.
Contact with nature reduces the forerunners of crime, reminiscent of stress and aggression, making individuals happier and fewer more likely to have interaction in crime. By giving individuals a spot to take part collectively in outside actions, the parks additionally promote constructive social interactions and neighborhood relationships in various city communities.
And when individuals congregate in parks and different inexperienced areas, "eyes on the streets" are extra seen, exposing criminals to fixed group surveillance.

Parks: crime sizzling spots or shelters?
Within the second stage of our research, we restricted our evaluation to city parks. The outcomes had been much less constructive.
By analyzing 4 cities in numerous components of the USA – Austin, Philadelphia, Phoenix and San Francisco – we discovered that violent crime was 28% to 64% increased in neighborhoods adjoining to parks than in neighborhoods with kilometer of the identical parks. Property crime was 38% to 63% increased in areas close to parks.
The one exception was Phoenix, the place the close by parks had no affect on property crime.
By zooming out of our pattern of 4 cities, now we have discovered proof that some parks really deter crime. Design and upkeep are important if we would like parks to scale back fairly than appeal to crime.
New York's Bryant Park, in downtown Manhattan, was as soon as a haven for legal exercise – a spot the place workplace employees averted strolling after darkish.

And the development of a brand new elevated path in Chicago appears to have made neighborhoods safer. Between 2011 and 2015, areas on runway 606 skilled 2.eight occasions much less violent crime and 1.6 occasions much less property crime than comparable neighborhoods in low-income Chicago throughout the identical interval.
Parks designed for safety, closely programmed and maintained always have a tendency to draw residents whose presence deters criminals.
This implies not solely facilities reminiscent of ball fields and cultural services, but additionally the lively participation of the local people and sources of sustainable and ongoing funding. When parks are allowed to deteriorate, decaying infrastructure and unhealthy popularity parks can flip them into legal magnets.
Crucially, program and panorama design should additionally replicate the group by which a park is positioned, creating public areas the place all staff, from workplace employees to native teenagers, can take pleasure in and benefit from the full vary of providers. Social, financial and well being advantages supplied by the parks.
Extra authentic customers of the park imply heightened surveillance and possession on a public house. This course of referred to as "territorial strengthening" is a elementary precept of crime prevention by means of environmental design.
City parks and inexperienced areas enhance the well-being of metropolis dwellers by selling bodily exercise, psychological well being and sense of group.
The discount of crime additionally is dependent upon the park, the town, the neighborhood and, above all, the standard of the administration of inexperienced areas in city areas.
