I have a survey data set with respondents geocoded.  I want to collapse the data set to the geocode level, so the simple command would be:

collapse varlist,by(geocode)

However some geocodes barely have any respondents and any collapsed data would be unreliable.  Is there a straightforward way to collapse only if the number of respondents is > 20 (e.g.)?

Many thanks,
