Frequently Asked Questions

How do I choose variable names?

Read the dataset’s variable definitions or groups first. Use the official names for the measures you need.

Can I compare different years directly?

Check definitions, geography, and dataset type first. A matching label alone does not ensure the estimates are comparable.

Can I query every geography in every dataset?

No. Geography support depends on the dataset. Use its official for and optional in predicates.
