Figures can be saved as .png files by clicking the three dots to the top right of each chart.
Notes for replication
▼The shapefiles for the Area of Responsibility (AOR) map are from the Deportation Data Project. I used mapshaper to simplify and convert them to TopoJSONs.
Notes for replication
▼Fields on crime are missing from the arrest data, while AOR is absent from the
detention data. I joined these files using shared unique identifiers. I cleaned for duplicates by removing entries that shared the same unique identifier and date.
I scraped the National Crime Information Center (NCIC) violent crime code manual from here.
About the Data
The ICE arrest and detention data were obtained through
a Freedom of Information Act (FOIA) request by the Deportation Data Project. The data
include administrative arrests from October 2022 through
mid-March 2026. The raw data files are too large to be kept in the GitHub repository, but can
be
downloaded from the website. I cleaned
for duplicates on the 'duplicate_likely' field in the processed data.
I used Python (pandas, numpy, BeautifulSoup) to clean data and Vega-Lite to
create the charts in this project. All my workbooks and .json files can be found in the
repository.
