This is an article reproduced from a thread by @abovetheclouds, thoroughly exposing Zenz and his statistical sleight of hand
It`s absolutely mindblowing that the claim by Adrian Zenz that "80% of new IUDs in China were fitted in XJ" is still repeated by the media. It`s been long debunked as a purposely misleading statistical sleight of hand. Time for a recap.
Adrian Zenz published his non-peer-reviewed report [1] for the neo-con Jamestown Foundation in June 2020 (1st version). His initial claim was: "In 2018, [the] share [of newly placed IUDs in China that were fitted in Xinjiang] rose to 80 percent"
This was, of course, uncritically repeated by various western mainstream media reports [2-5], with none of them explaining the definition of this quantity.

In contrast, Chinese media [6] did right away refute Zenz` claim by checking his source, the Annual Health and Hygiene Statistical Yearbook of China 2019 [7], and by calculating the correct share, which is 8.7%, not 80%.
Zenz then did update his report [8], changing every occurrence of "newly placed IUDs" to "net added IUDs". I`m not aware of any public announcement of this update, which isn`t conforming to the standard of an academic erratum listing the changes
