According to the stats in the linked document:
Total of initial issues and current pilots in the 2011/12 reporting year: 38,271
Total of initial issues and current pilots in the 2015/16 reporting year: 30,547
It is not possible to infer much from the medical certificate statistics over that period, because of the changes in query parameters and the fact that a Class 1 certificate comes with a Class 2 as well, and the durations of each are different.
But anyone who thinks GA is in robust good health and growing is either delusional or a paid spin doctor.
