st: Aggregating medians in a group (median county income over metro statistical areas)

Hello all,
My question is two part, (a) statistically sound method to aggregate (b) how to do it in Stata
My primary data set is made up of Metropolitan Statistical Areas (MSA) in USA. Each MSA may have several counties. To the best of my knowledge, MSA->County is 1:m relation.
In a secondary data set based on __COUNTIES__, I have (i) median household income (ii) population.
(a) what would be sound method to aggregate household income over MSA (given the constraints of available data). I thought of doing a population-weighted mean of the median household income ... however, I am unsure if this is a sound aggregation
(b) how can this be done in Stata (unless the answer to (a) implies a straightforward procedure)

Thanks,
Tanuku
