Before 1958, Kumbum had 3600 monks. At present, there are 400, as the monastery was affected by Chinese Communist policies since the late 1950s. Of these, 300 are at the Debate College and the rest are distributed evenly among the other three colleges. Traditionally, the majority of the Kumbum monks have been Tibetans from Amdo, as at Labrang Monastery. The remainder have been Khalkha Mongols from Mongolia () or Inner Mongolia (), Upper Mongols () from Amdo east of Kumbum or Yugurs () from Gansu.
