The FAQ almost answers the question, but not quite: to get
one random individual per household (as opposed to a random
sample of households), try:

 set seed 12345678
 gen random=uniform()
 bys household (random): gen byte mysample=_n==1

Then -mysample- will be one randomly selected individual
per household.

I have a data set where each record is an individual in a household. I have
all members of each household. How do I make a dataset that has only one
randomly selected member from each household?
