Democracy does not function the same way in every US county. It functions through infrastructure - organized parties, voter registration, campaign money, legal access, and the public institutions that make participation possible. Volume 4 documents where that infrastructure exists and where it doesn't.
143 US counties have no Democratic AND no Republican committee. Q4 counties generate 25.8 times more campaign money than Q1. Counties where more people vote live 2.82 years longer. 981 US counties are legal aid deserts. The census mail return gap costs distressed communities a decade of underfunded federal programs.
15 documented findings across five chapters. 5 county portraits. All sourced to FEC, Census, voter participation, and federal program data. Dataset archived at openICPSR: https: //doi.org/10.3886/E247201V1
