Abstract: The 7th Population Census has achieved the lowest underreporting rate in history and is therefore a highquality census. The improved quality of the data is not only due to the great social organization and mobilization capacity of the Chinese government, but also closely related to the new measures adopted in this census, including digital data collection, additional channels for respondents to register online, matching and verifying data by using administrative records across multiple sectors, and ID number collection. The 7th Population Census reflects new “changes” in the population, which may improve the knowledge of objective facts about the population. The current population of China is characterized by “a larger total population, a higher proportion of the young and of the elderly, and a lower proportion of the working-age population”.
