I'm compiling some comparisons of 2006-08 ACS and 2000 Census data, and I'm looking for some guidance in estimating standard errors for 2000 CTPP tables. For the place of residence data, I have applied the estimation procedures outlined in the 2000 SF3 documentation:
 
    Unadjusted standard error:
        SE(Y) = sqrt(5*Y*(1-Y/N)),
    where N = size of publication area (total population) and Y = estimate of characteristic total
 
This value is then multiplied by a design factor determined by the state, sample rate and characteristic.
 
Are these methods also applicable to the workplace (CTPP part 2) tables? If so, what assumptions can I make about sample rates, and are the standard error design factors applicable to place of work statistics?
 
Any advice will be greatly appreciated.
