The argument I make in my research is that the Uighur population figures of most recent dates are probably accurate. They have been catching up. In some years, they've added quite a few to the Uighur population.
The Uighur population growth was one of the highest in China. A lot were born in violation of birth control policies; therefore, there was a significant Uighur population that was not recorded, and there was no record on them. This was a big issue in the eyes of the government. I believe that's one of the main reasons they're engaging in this demographic genocide, birth prevention, to have a tighter control of the population. You see sudden spikes in population in Uighur regions.
I think the most recent figures of the Uighur population are quite accurate, and they reflect a dramatic decline in their population growth.
