There are two ways, depending on what your goal is:
1. You can weight each observation so that the sample times the weight
equals the population size. This will make the "population size" output
correct.
2. If your intention is to do finite population correction, then you can
create a new variable equal to the stratum-specific sample divided by the
stratum-specific population and then assign this as your fpc()
parameter(alternatively, I think the FPC variable can be just the
stratum-specific population size - check the manual).
