This will select one person randomly per household:
gen randomvar = uniform()
bysort householdid (randomvar): gen selectionflag = _n==1

Subject: st: select a random obs from dataset
Dear all,
My colleague wants to know how to select a random obs with some
conditions
from her dataset.
She wants to select one person randomly per household, but also with
condition that there is
no repetition of household (no household should appear twice in the
outcome,
although the
person is different).
I don't know the method and I don't know if this can be done by Stata or
not. If there is a way, or some suggestions, I would appreciate very
much.
Many thanks in advance.
Akihito
