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. <br><b>To use:</b>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!<br><br><b>Disclaimer:</b>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.

本数据集用于开展警方介入致平民死亡对凶杀率影响的相关研究，包含所有分析文件与原始数据。具体涵盖：美国44座城市的汇总凶杀案与加重袭击（aggravated assault）数据CSV文件、R项目文件、可实现可复现清洗流程的R脚本、可生成可视化图表的间断时间序列分析文件、可生成森林图（forest plot）的元分析文件，以及附带新闻报道链接的警方枪击平民记录。<br><b>使用方法：</b>请将所有文件下载至同一文件夹，通过RStudio调用R软件打开该R项目文件。本数据集已尽可能实现各组件独立运行，以最大化研究的可复现性。您可能需要安装相关R包（RStudio会自动提示缺失的包）。若需重新运行清洗脚本，您需下载统一犯罪报告（Uniform Crime Reporting, UCR）数据与各城市犯罪数据，本文已提供这些数据源的链接。除此之外，所有流程均可直接运行！<br><br><b>免责声明：</b>本数据集不包含各城市与统一犯罪报告（UCR）的原始数据文件。尽管未附带这些案件级原始数据，但除坦帕市数据系通过数据申请获取外，其余数据均已公开，且本文已提供相关链接。本人乐于为有需求的研究人员获取源数据提供协助。
