]]>The release covers eight demographic cells — race ∈ {AM, BL, HI, WH} crossed with sex ∈ {F, M} — across three CRDC collection years (2015–16, 2017–18, and 2021–22), for U.S. school districts (LEAs) and states.
Two artifacts are published on Hugging Face under release
civilytics-crdc-arrests-2025.1:
summary.duckdb (~260 MB) — a compact DuckDB with the tables that power the
live API: arrest_summary (LEA grain, ~2.27M rows), state_summary,
district_dim (names + geography), and a meta table. This is the file to grab
if you want point estimates and intervals.parquet/ — the full raw posterior draws (500 per group), Hive-partitioned
by model_id / YEAR / LEA_STATE across ~1,387 shards. Reach for this if you need
to propagate uncertainty through your own downstream computation.You can query a single slice straight from Hugging Face with DuckDB — no full download required:
