Can someone please set me in the right direction for coding a program to count and eliminate data if it doesn't meet a certain criteria?

I have survey data taken over 26 years and the survey area is divided into subareas. I want to only include a subarea if data was collected 13 years out of the 26 and data must have been collected 2 years of the first 5 years and 2 years of the last 5 years. If the subarea does not meet that criteria, I want Stata to drop that subarea from the analysis. At the moment, I'm having to look at everything individually and it takes several days to eliminate subareas.

Thank you,
Jennifer
