Counting variable data within a list

[pchapple]

Hello

Here's one Im stuck with.  I have 2 stores, each service people with different Citizen codes.  I want to be able to COUNT the number of times that citizen code appears in a list, but without hard coding EACH of the citizen codes. (the list is extensive, snapshot below)

At present I have a measure for each citizen code  // AUS = CALCULATE ( COUNTROWS (Sheet1),Sheet1[Citizen]="AUS") // but this means I need to create a measure for each citizen code individually, and the lists can grow regularly so its hard to keep up.

Is there a way that I can the system to recoginze the unique citizen code values in the list, then count those unique values, but without having to create individual measure for each citizen code?

Measure = CALCULATE ( COUNTROWS('Table'), ALLEXCEPT('Table', 'Table'[Citizen]) )

Measure = CALCULATE ( COUNTROWS('Table'), ALLEXCEPT('Table', 'Table'[Citizen]) )

Thanks @Sean, this is great.

Yes the above will give OVERALL Total at the Citizen level no matter what - useful for calculating % at the Citizen level (NOT Grand Total)

Yes if you'll use Slicers just use Total = COUNTROWS(Table) with no filters!

Hope this helps and makes sense!
