In 1950, when the Chinese communist army came to the region under the command of Wang Zhen, there were about 2,500 to 3,000 Chinese in the whole area. Now even the Chinese government says it is 46% Chinese. If you include paramilitary forces, or some seasonal workers, the overall Chinese population could be more than Uighurs.
More Uighurs are now in jail, and opportunities are only provided to the Chinese, who are coming. Uighur girls are forced to marry the Chinese. There are home-stay programs for Uighur families by Chinese officials with a 24-hour watch. Basically, the Chinese are the dominant power at every level of life, not only at the government level.
