Not only that, the statistics for 2018-19 also show that:
* Despite the birth rate in Xinjiang being cut more than in half between 2014-19, there was still a slight birth surplus of 0.37% in 2019.
* But the population in the province increased by 1.45% between 2018-19, meaning that 1% of the growth that year came from colonization of ethnic Chinese to the province from other parts of China.
So, China is not only sterilizing the Uygur women, but also massively colonizing the region with their own folk.
The sterilization is its own thing, of course, but this part is a tactic the PRC has probably used before to deal with restive parts of the country outside China Proper. They've been accused of doing it with Tibet over the past ten or twenty years, although not with Inner Mongolia, which has been mostly Han for at least a century.
