I don't think there is - I've wanted to do this as well before - it would be a nice addition to have
Thanks for the quick response.
I know that this is a 4 years old thread.
Tableau software has been updated in this 4 years, I wonder if the latest tableau software could extract income data by zip code from the map?
The data layers are currently only available as background maps and not as data. We certainly do hear this request, but at this time we are not able to make that data available.
You may want to add an idea to our Ideas Forum or vote for an existing one.
With Version 9, if you had (or could download) a separate data source that includes income data at a low enough level of granularity, then it may be possible that data blending and LOD expressions could help you evaluate the Income per Capita at various levels, like Zip Code, City, State, etc.
I don't have an example handy, but with the appropriate data connections, nearly anything is possible! And Version 9 LOD expressions are just amazing.
