Map of Arrest Locations

This map displays all arrests for marijuana related offenses in NYC between January 1st, 2014 and December 31st, 2014. The street price of marijuana at the date of arrest is signified by the color of the data point. A scale describing the color gradient used to plot the points is detailed to the left of the map. The darker colored dots represent more expensive marijuana, while the lighter colored dots represent cheaper marijuana. The goal of this map is to illuminate different trends in the location and prices of marijuana for related arrests, and to see whether the price of marijuana influenced the frequency of arrest. For example, we questioned whether there would be more clusters of arrests at locations where marijuana prices were higher. One noticeable trend is that there are mostly arrests at higher price points in Queens compared to the other four boroughs. It also appears that the density of arrests is not necessarily correlated to the price in that area.
