st: semi-random sampling

Dear all,
I need to take a subsample of observations from a big dataset making
sure that the people in the subsample have a given geographic and age
profile. I need to make sure that, say, 50% of people in the subsample
come from the capital and 50% from other towns. Within each of these 2
locations I want to preserve a certain age structure: say in a city: 3
people ages 23, 4 people aged 24 …
Within those geographic and age profiles I want to select the
observations randomly. Is it possible to do that in Stata 11? Any
thoughts on how I would go about it?
Looking forward to hearing from you,
Sincerely yours,
Ekaterina
