This data set contains a complete list of crimes committed in Chicago between the years 2001 – 2019 (inclusive), and was studied by Sainsbury-Dale, Zammit-Mangion, and Cressie (2021). 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.
