Not sure if this helpful. There are 487 PHCs with caseloads. 683-241 members per case load. Seems to depend on what states you have. There are 285,700 members. The most recent from leadership is that 110,000 members graduating. At best they can retain 251 PHCs.
Thanks for this, OznBmjE-1kzv, was wondering about the numbers. I doubt this is the only factor, but it gives some idea.
