Why dont the svyset commands specify a finite population correction (fpc)?
It is possible to add this term, but it has little practical effect on standard errors. In our trials, standard errors deviated at only the 3rd decimal place when specifying a finite population correction for the MQ dataset (computed as the number of achieved observations divided by the population total, with the latter indicated in Table 2.1 in the WERS 2004 Technical Report). Use of the term is also questionable when using non-random subsets of the full data set. It might be noted that NatCen (the fieldwork company for WERS) did not use this feature when computing design effects for the WERS Technical Report.
