The puma geography ids are unique only within states. Appending the state code to the front would make a national unique geographic identifier. That would make substate online queries across state lines easier. I understand I do this myself with downloaded data. Let me know if there is a way to do this online & I missed it. Best.
Since pumas are unique only within state, could there be a state-puma variable online that would be unique?
You can create a temporary variable in the Online Data Analysis system that concatenates STATEFIP and PUMA. Navigate in the SDA menu to “Create Variables => Compute a new variable”. Enter “statepuma=(statefip*100000) + puma” into the “Expression to Define the New Variable” field. This will create your variable of interest.
Hope this helps.
