Discover Public Datasets With Google Dataset Search
Dataset search helps locate data sources; licensing and quality still require checking.
The aim is to help you complete one clear task, recognize what needs verification, and avoid the most common mistakes. Work through the checks in order, then use the real-world example to apply them to your situation.
Cost classification: Free resource (core access). Review the provider's current official terms before relying on an offer; separate core free functionality from optional upgrades, accounts, storage or third-party charges.
1. Search for an exact measure
Use precise terms, region and year, such as city air pollution annual readings, rather than typing an entire research question. Dataset Search indexes metadata from many publishing organizations.
2. Open the original publisher
Read the source record for collection method, geographic coverage, refresh frequency and download access. The search result may describe a dataset that requires registration or has licensing restrictions.
3. Examine file and schema
Check whether values are CSV, API, spreadsheets or a specialized scientific format. Identify units, missing values and identifiers before building a chart or comparison.
4. Record provenance
Cite the originating publisher and dataset version, not merely the search engine result. Keep the date accessed and a copy of any licensing conditions that govern reuse.
