Chicago Crime Data Project

The Chicago crime API displays crime statistics in a number of formats, date, type, if an arrest was made ect. However I feel it’s missing a necessary component, displaying historical data according to dates. Criminals are human, they are affected by natural effects and crimes fluctuate based on the time of year. For example the sites primary purpose will be displaying all crimes committed on the current date every year back to 2001. Additional functions will be displaying crime data by the week. Having a better understanding of when crimes happen will help us understand why they happen and how to prevent them.

This site shows a readout of all crimes commited on the current date. Other days can be selected using a date picker or buttons that advance or subtract the dy. Below that is a readout of the 10 days that have most and least number of crimes reported. Clicking the day will change the main graph to that day. Below that in its default state is a graph of all crime committed by month and year. Clicking on a single year on the legend will show only the crime data by month for that year. Clicking on a point on that graph will show crimes for that year by the day of the month. Clicking on a single point on that graph will show al crime committed by the hour of that day. Finally clicking on a single hour point on that graph will display all crimes committed on that hour of that day. Another bar graph will be displayed showing the crimes by type. When the user is zoomed into this level below the bar graph will show a detailed readout of all crimes that were committed within that hour. Data such as crime type, description, if an arrest was made, FBI code and others.
