There are five categories in the marriage variable and I have two time points and two groups each with say, 50 people. The trick is that the proportion is the mean of a dummy/indicator variable, so: *-------------- begin example ----------------- sysuse nlsw88 bys race: egen p_mar = mean(married) bys race: egen p_n_mar = mean(never_married) *------------- end example ----------------- (For more on examples I sent to the Statalist see: http://www.maartenbuis.nl/example_faq ) Hope this helps, Maarten -------------------------- Maarten L.
