The original version of the China subregional model had a population series that ran from 1960 through 2013. The original data dictionary entry for this series said that the population series was sourced from the Central Statistics Organization and that there was data for 1999 and 2003, which was clearly incorrect. The original source has not been found and because the source could not be verified and some of the data appeared questionable, this population series is not being used. The largest issue with the data was the appearance of possible sorting errors and some large transient data points, most noticably in Chongqing during years prior to 1997, when it became a municipality. | The original version of the China subregional model had a population series that ran from 1960 through 2013.

The China Data Center database from the University of Michigan has population data from 1949 through 2003. This data was considered as a potential source for blending with the current population data to provide a longer historical time series. However, the series was not blended because the data from 1995 through 2003, where the two series had overlap, did not match. | The China Data Center database from the University of Michigan has population data from 1949 through 2003.

Central_Statistics_Organization
The original version of the China subregional model had a population series that ran from 1960 through 2013. The original data dictionary entry for this series said that the population series was sourced from the Central Statistics Organization and that there was data for 1999 and 2003, which was clearly incorrect. The original source has not been found and because the source could not be verified and some of the data appeared questionable, this population series is not being used. The largest issue with the data was the appearance of possible sorting errors and some large transient data points, most noticably in Chongqing during years prior to 1997, when it became a municipality.
China_Data_Center
The China Data Center database from the University of Michigan has population data from 1949 through 2003. This data was considered as a potential source for blending with the current population data to provide a longer historical time series. However, the series was not blended because the data from 1995 through 2003, where the two series had overlap, did not match.
