Manhattan Crime Incidents in a Day

Description:

Do you remember what you were doing on Thursday, June 1st, 2017? For me it was only a typical workday of my summer internship. Across New York City a million stories emerge over the course of a single day. This project explores crime incidents across New York City over the course of a single day.

354 crime incidents of all categories!

I’ve created a crime incident map to visualize where, when and what kind of crime that happened on this single day, to help you protect yourselves from appearing in some place in a certain time of a day.
