I'm Chinese and literally grew up with Uyghurs downstairs in Hubei, they and the Hui family around the block were the only ones with more than 1 kid.

If you're referring to something Adrian Zenz said about 80% of new IUDs being sold in Xinjiang, he misread a decimal point 328,475 IUDs in Xinjiang out of 3,774,318. 8.7% of IUDs placed in China were in Xinjiang.

News quoted his 80% figure before he had to retract it, but it's already in the back of people's minds that China's forcibly sterilizing Uyghurs.
