Crime in Chicago: 2001 to 2019

A complete list of crimes committed in Chicago between the years 2001 – 2019 (inclusive), and was studied by Sainsbury-Dale et al. (2023). The data were provided by the Chicago Police Department and originally downloaded from the now retired open data source website, Plenario.
Before pre-processing, the data set contained 7,138,725 observations. However, 68,904 observations did not have a location recorded and were removed. A further 163 observations were removed as they were recorded at coordinates (36.619446395, -91.686565684), which is on the border of Missouri and Arkansas (certainly not in Chicago, Illinois). This left 7,069,658 valid observations.

id : An identifier unique to each crime.
case_number : The case number of each crime.
date : The date and time at which each crime took place.
block : The neighbourhood block at which each crime occurred.
primary_type : A factor indicating the type of each crime (e.g., burgulary, theft, etc.).
