Abstract
This chapter describes in detail the Chicago homicide data that were used to conduct this study, as well as how the data was geocoded and aggregated to grid cells for spatial data analysis. The Chicago homicide data is emphasized in terms of domestic vs non-domestic homicides, which provides a useful framework for understanding some of the variations of violence at micro places. The chapter concludes with a description of the geographic levels of analysis that were used, including how and why the 150 m cells were selected as the primary unit of analysis.

Notes
- 1.
The CHD begins with 1965 homicides because it was the last year of a period with relatively few homicides. Here we use the year the injury occurred for the historical homicide dataset. This results in three cases being dropped in which the incident occurred in 1964. The contemporary homicide dataset uses the date the incident was reported.
