Public Datasets
Free, openly available datasets published by governments, institutions and open-data communities.
Public datasets are freely available data published by governments, research institutions and open-data communities, covering everything from economic statistics to geospatial and scientific data.
They're often the right starting point before spending on commercial data, provided licensing and update frequency meet your needs.
Typical sources
- Government open data portals
- Academic and research repositories
- Community dataset hubs
Common formats
- CSV
- JSON
- API access
Buying tips
- Always check the license attached before using data commercially
- Verify update frequency matches your project's freshness requirements
- Cross-check data quality against a second source where possible
Compliance notes
- Public availability does not guarantee unrestricted commercial usage rights — check licenses individually
