The map above shows the average annual population growth rate of the 31 provinces, autonomous regions, and municipalities under direct jurisdiction of the national government (Hong Kong, Macau, and Taiwan are not included) according to the latest official estimates, which is currently the 2020 Census of the People's Republic of China. Results can be found here and here.
The timeframe used for this map will always be between the most recent official population estimates and the most recent official Chinese Census results (or in the case that the most recent official population estimates date to a census year, then the census before that one). So currently, the timeframe for this map goes from the 2010 Chinese Census populations to the 2020 Chinese Census populations.
This file should next be updated when the 2021 Chinese population estimates are released. The timeframe of this map will then be switched from "2010 - 2020" to "2020 - 2021". 
Average Annual Growth Rates are used instead of the total percentage growth rate since the last census for consistency and to prevent a new legend from being used every single year.
