About this page
ZOVA’s analysis is built on public and open data. Most of it is U.S. government work in the public domain and needs no credit. The sources below are the ones whose license or terms ask for credit, with that credit given exactly as each asks for it.
Where a report draws on one of these sources, its sources list repeats the credit, including where the source only fed a ZOVA score, and every sources list links back here.
