It's really wonderful for you to link the dataset here. I think neither of us would have the time to compile the dataset manually. Admittedly and regrettably I didn't check the appendix.

So the conclusion was from Xinjiang's 2017 and 2018 birthrate, which respectively as included was 15.88 and 10.69, so that's where the 50% drop came from. However, the same index for China overall was 12.43 and 10.94, where we see around 20% drop. I don't think it can be categorically concluded it's some racially-motivated policy. (whether it's a good policy or bad is a whole different matter.)

So to summarize our discussion:

Me: Here’s an article about this report.

You: The press is misrepresenting the abstract.

Me: Nope. Here’s the full report.

You: The report draws the wrong conclusions. Besides, they don’t even share the dataset.

Me: Nope. Here’s the dataset linked in the report.

You: The data show that Xinjiang birth rates declined 30% more than they did in the rest of China. As you can see I was right all along.

I’m curious how you managed to make this journey. It doesn’t seem like you’ve been participating in this discussion in good faith, frankly. I could be wrong though. In that case, I would recommend you actually read what people are trying to show you before attempting to criticize it. You are clearly working backwards from your priors.

Well, I guess you know how to spin a story. My point the whole time has been that percentages can be misleading without the actual number presented, still you seemed to be only cares about the percentages.

It's quite easy to see that birth rate in Xinjiang falls around the national average in 2018. Stil, I'm glad you found the actual dataset in the appendix.
