The unrecognized minorities include over 730,000 individuals. This is a fairly small number considering the total populaiton of China.

The Unauthorized Official Report: The minority population of China is growing faster than the majority is: Han Chinese.
The minority population growth rate increased from 6.1 % in 1953 to 9.44 % in 2005.

Causes for this include China's Constitutional statement to promote the economic and cultural development of China's minorities. This is done by exempting the minorities from China's One-Child Policy. These minorities are also given preferential treatment: religion, language, and financial aid.
