I am trying to compare the size of the workforce in my city, as reported by the 2012-16 ACS, to the size reported by the 2000 CTPP Part 2 Table.  While I can do a straightforward comparison of figures, I’d like to evaluate the difference taking into account the 90% margin of error. 

I can use 2000 Census documentation to determine how to compute MOEs for figures reported for my community’s own population, households and housing stock.  However, I am not sure how to approach this problem for the workforce, since the workforce is based on a sample from a larger population, perhaps county, state or national.  Any suggestions are appreciated.
