Count how often an ID occurs in a column

[Valentin Heinrich]

Hi,

I have a question which should be fairly easy to answer. I have a variable in my dataset called ind_id (individual ids). I want to get an overview of how often each ID occurs in the column. Ideally, I could also perform some basic descriptive statistics on the result (i.e. max/min, average, percentile). Thanks for your help.

Best, Valentin

by ind_id, sort: gen id_count = _N if _n == 1
summ id_count, detail
