ProPublica Data Store
propublica.org/datastore
A collection of datasets compiled by ProPublica journalists for investigative reporting, many available for free download.
Why it is useful
Provides cleaned, documented datasets that represent real investigative journalism work — including data on political spending, healthcare quality, government contracts, and criminal justice. These are datasets that ProPublica paid to compile and clean, made freely available. For journalists and researchers, they often represent months of FOIA requests and data processing work.
