So what happened in 2017/2018 that reduced the birthrate? The only major event was the trade war, but economically 2017-2019 wasn't that bad. So what's your theory on why there's such a sudden decrease in fertility?If you look at the statistics I posted above, the drop in China's birth rate is not due to Covid. The number of marriages has been falling since 2013 and are down 50%. The birth rate started to plunge in 2018. There was an 15% plunge in births already apparent in 2020, but that cohort of mothers mostly conceived in 2019. Also, the decline in first marriages accelerated in 2019, which could explain that drop. So the trend definitely precedes Covid.
