The U.S. Census counts roughly 90,000 governments.
Questions
Questions this open dataset can help answer.
For residents, reporters and researchers:
- Q1 Who represents me, at each level of government?
- Q2 Which public offices and services are run by the governments where I live?
- 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.
Model
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.
Principles
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.
