Every level of U.S. government.

The directory spans federal, state, county, special district, city and school district governments, not just one level.

  2. State
  3. County
  4. Special District
  5. City
  6. School District

The U.S. Census counts roughly 90,000 governments.

Questions this open dataset can help answer.

For residents, reporters and researchers:

  1. Q1 Who represents me, at each level of government?
  2. Q2 Which public offices and services are run by the governments where I live?
  3. Q3 How do services compare across cities and counties?

Answers depend on what is recorded. The directory does not decide who is eligible for a service.

How the data is organized.

  • Jurisdictions
  • Agencies
  • Boards and councils
  • Positions
  • Services
  • Resources

The goal is to document every elected office and government agency. Resources are the documents and datasets most governments publish: charters, bylaws, budgets and open data portals. Every record carries its source, and contributions are reviewed before they publish.

Values.

Transparency
Government data that anyone can read and check against its source.
Civic participation
Residents who know who governs them can reach the right office.
Useful and usable
Practical tools that serve real needs, not data for its own sake.
