If you asking particularly about India then i must say that it is below average. It is not that Family Medicine is bad field but it is only advised if you wan to open your own clinic. Otherwise if you want to practice in any Corporate firm then i would not advise you to take up Family Medicine. It is not like that you are not getting your desired Stream hence taking up Family medicine, please don't do that.

Otherwise if you want then i am listing down few good institutions for this course:

Sir Gangaram, Delhi

Stephen's Delhi

MGIMS

Deenanth Mangeshkar, Pune

CMRI, Kolkata

Holy Family Hospital, Mumbai

All the best!!!
