Hi Ben do you have a sample of this data that you mention.
It should be as simple as right clicking on your state/ city field and changing this to a geofield
But if you can attach a sample of data we can help you achieve this and confirm that it is possible with the data you have.
What do you mean by "fields"?
In your worksheet the fields are in the data pane on the left broken up by Dimensions and Measures.
Ah, just didn't know the official terminology. Thanks. When I right-click on the state field, as instructed by Khalid, I see the option to convert it to measure but nothing about changing it to a geofield.
Can you send across a screenshot of your fields within tableau,
The icon to the left of this should be a small sphere representing it is a location field .
if it is not on when you right click there should be a submenu geographical role.
Let me know how you get on with finding this menu
The built-in data under Map/data layer cannot be accessed for analysis outside the Tableau mapping functionality. You can access layers below state by selecting a data layer then look at the By: drop down menu to select County, Zip Code, or Block Group to get a the data below state level. At Block Group, of course, you will want to zoom in quite a bit.
I have found that census tract level is useful for many reasons. See by blog post on this topic at: The Case for Census Tract Demographics — TGE Demographics Consulting
Also, I have posted a free sample of this data at: Data for Tableau — TGE Demographics Consulting for the California Hispanic Population data. The background maps are from Mapbox so instructions on how to get those are included. This was my attempt to integrate my own demographic data into Tableau (ACS data) so as to get beyond the built-in data.
Let me know if that works for you or if you have further questions.
