Police-involved deaths and homicides - data and analysis files
Analysis files and data for study of effect of police-involved civilian deaths on homicide rates. Includes csv of aggregated homicide and aggravated assault data for 44 US cities; an R project file; an R script for reproducible cleaning process; an interrupted time series analytical file, which also produces plots; a meta-analysis file, which also produces forest plots; records of police involved shootings with links to news reports.
Download all into one folder and open the R project file with R using RStudio. I have tried to make these fully functional on their own to maximise reproducibility. You will likely need to download packages (but RStudio should prompt you to the ones that are missing). If you want to re-run the cleaning file, you will have to download the UCR and city crime data. I have provided links to these sources. Otherwise, everything should run out of the box!
I do not own the original data files from cities and UCR. While I have not included these case-level data, they are all publicly available and I have provided links, aside from Tampa which I acquired through a data request. I am happy to assist any interested researchers with getting the source data.
Update 17 June 2022:
Previous versions did not include 'final protested list.rds', which is essential to run analyses. This is now added.
