Where gt is the proportion in the total sample and gs is the proportion in the sub-group, nt and ns are their respective effective sample sizes, and ws is the proportion of the total population in sub-group s:

z=gtgs(1ws)deff(ses2+sek2),

where:

p=2(1Φ(|z|)).
gk=(gtgsws)/(1ws),
sek=gk(1gk)ntnsb,
seg=gg(1gg)nsb,
b is 1 if Bessel's correction is selected for Proportions in Statistical Assumptions and 0 otherwise,
deff is Extra Deff, and
ws is the proportion of the Population represents by the sub-group.
