Data sources

The public data Jurisdictional is built on.

Every record here traces back to a source. Each source below has a page with its publisher, how far we trust it, what we use it for, live counts measured from our database, and every run we have recorded. We name each publisher and link to its data. Listing a source does not mean its publisher endorses Jurisdictional.
