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. To use: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!Disclaimer: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.

本数据集包含用于研究执法致死平民案件对凶杀率影响的分析文件与数据，具体包括：经汇总的美国44座城市凶杀与加重伤害犯罪数据CSV文件、一份R项目文件、一份用于实现可复现清洗流程的R脚本、一份可生成绘图结果的间断时间序列分析文件、一份可生成森林图的元分析文件，以及附带新闻报道链接的警方枪击事件记录。
使用方法：将所有文件下载至同一文件夹，通过RStudio调用R打开该R项目文件。本数据集已尽可能确保各组件独立运行，以最大化研究可复现性。用户可能需安装相关依赖包（RStudio会自动提示缺失的包）。
若需重新运行数据清洗脚本，则需下载统一犯罪报告（Uniform Crime Reporting, UCR）及各城市犯罪数据，本数据集已提供相关数据源链接。除此之外，其余组件均可直接开箱即用。
免责声明：本数据集未包含各城市及统一犯罪报告的原始数据文件。除坦帕市数据系通过数据申请获取外，其余所有案件级数据均为公开可得，本数据集已提供相关来源链接。本人乐于为有需求的研究人员协助获取原始数据源。
