Frequently Asked Questions

Can I use government data for commercial purposes?

Yes! Government data is typically public domain (especially US federal data) or released under open licenses that allow commercial use. Always check the specific license, but 99% of government data is free to use for any purpose.

Do I need to cite the source?

While not always legally required for public domain data, it's good practice to cite your sources. A simple "Source: data.gov" or similar attribution is usually sufficient.

What formats are available?

Most government portals offer data in multiple formats including CSV, JSON, XML, and Excel. Many also provide API access for real-time data retrieval.

How current is the data?

Update frequency varies by dataset. Economic indicators might update monthly, census data annually, while some real-time feeds (like weather) update continuously. Check individual datasets for update schedules.
