Pokemon GO quickly became one of the most popular mobile games. In cities all around the world, you can see people searching for Pokemon and battling other players in Poke Gyms. While exploring this new augmented reality, it’s easy to forget about the dangerous of the real word. On a daily basis, news sites report on Pokemon Go related incidents like child abandonment, reckless driving, or trespassing. Earlier this month New York Governor Andrew M. Cuomo even banned sex offenders from playing the game.

These incidents gave me the idea for this article about PokeStops in potentially unsafe areas where caution is advised. My goal was to analyze public data to identify PokeStops in New York City which are close to crime scenes and registered sex offenders.

PokeStops Near Crime Scenes

First, I used PokemonGOMap.info to get the locations of the 24 thousand PokeStop in NYC and download all reported felonies of 2015 (103k) from the NYC OpenData portal. For this analysis, I exclude the offenses burglary (15k) and grand larceny (49k) because they’re less a potential threat to players in the area. The following map shows all PokeStops as blue dots whereas incidents of felony assault & robbery (37k) are represented by green dots and murder & rape (1.5k) by red dots.

Next, I loaded the raw data into R* to count all crimes that occurred within 150m (492ft) of each PokeStop. I had to choose this rather large area because the public data doesn’t show the exact location of the incidents due to privacy reason. Instead, it only provides the midpoint of the street segment on which they happened.

The map below shows the top ten PokeStop in which proximity most major felony incidents occurred. For this map, the offenses murder and rape are weighted by the factor five and only the top PokeStops of an NTA are included to reduce regional clusters. You can find the total number of murders & rapes in the areas of the PokeStops in the red boxes and total number of felony assaults & robberies in the yellow boxes right next to them. The average number of incidents of all NYC PokeStops stands at 0.15 for murder or rape and 4.00 for felony assault or robbery.

PokeStops Close to Sex Offenders

Another question I researched was how many registered sex offenders live close to PokeStops. I downloaded their addresses from the website familywatchdog.us. For the analysis I only selected people who were convicted for offenses against children and/or rape. The following map shows all PokeStops with the color of the dots indicating how many registered sex offenders live in a 150m (492ft) radius.

The numbers show that 11.4% of all PokeStops in NYC have at least one sex offender living nearby. The next table lists the top ten PokeStops by the total number of offenders living within 150m.
