Hello-

I am working with the five year ACS data, and we are trying to create profiles for the unincorporated portions of the county.

My question(s) is: If I sum up the estimates for all the municipalities in their respective county can I simply take the difference from the county total and call it the unincorporated part? If so, how do you obtain the MOE for this number? Can you “back out” the MOE from the adjusted (square root of the sum)muni MOEs and the  county MOE? Or do I have to  aggregate block group data for these areas?

Thanks in advance for your help!
