Plenty of Chinese ones in subs like /r/China_irl etc., not seeing much traction of this story/dataset in Western world, though (hell, even on HN it barely got any upvotes 2 days ago.)
Take these threads with giant grain of salt though, they're far from thorough and some of them lack basic understanding of statistics. And I personally don't think the dataset (at least the sample) is actually random so not really a good representation of China's demographics.
Any links?
