This data is going to be released on January 17.
Bottom line: In 2021, births dropped 11.5%. A further 11.5% drop would take births to 9.4 million. Below that is bad; above that is good.
However, there are a couple reasons to suspect that births may be higher than 9.4 million:
1) China liberalized its birth policy in May 2021 to allow a third child. During the previous liberalization, which was announced in November 2015, a brief baby boom followed in 2016. Parents who heard of the new policy in May 2021 and thus started trying to have a third child, would have had that child born in 2022 if they were successful.
2) The number of marriages dropped only 6.6% in 2021. The number of births tends to track with the number of marriages. If we used that barometer instead of linear extrapolation, we would get 9.9 million births.
There are
saying that He Yafu, an independent demographer, "predicted that the number of newborns in China fell by 5 to 10 percent from 2021, stood at a number between 10.09 million and 9.56 million."
That seems reasonable to me. Overall at this point, 9.4 million would be slightly disappointing for the reasons above, but over 9.5 million would still be good news.
