Where do the most homicides in Boston occur? According to data from the Boston Police Department, 493 homicides occurred between 2006 and 2014. 239, or about 48%, occurred in police districts B2 and B3, which constitute Roxbury, Mattapan, and North Dorchester. In spite of tough gun control laws in Massachusetts, the overwhelming majority of deaths resulted from gunshot wounds. While homicide rates have dropped in Boston on the whole, non-fatal gunshot wounds and gun violence rates have increased.
In order to visualize this data, I first cleaned the data by standardizing all of the locations — typing out street addresses, and adding city and state information. I then used a geocoding tool to find the geographical coordinates for each location. I used this data to populate a map on CartoDB, which I plotted over a base map of Boston’s police districts. Ideally, I would have liked to be able to create a code to isolate the map based on certain variables — by year and by district, so that one can easily see when and where the homicides were happening.
