Among the victims in Inner Mongolia, 75 per cent were Mongols, even though they only constituted 10 per cent of the population. In 1969, much of Inner Mongolia was distributed among surrounding provinces, with Hulunbuir divided between Heilongjiang and Jilin, Jirim going to Jilin, Juu Uda to Liaoning, and the Alashan and Ejine region divided among Gansu and Ningxia. This decision was reversed in 1979.
