     *Timeliness (the interval between the end of statistical standard time and data release time):
Based on comprehensive data to compile general report after two years completion of the survey (November 2020).

     *Major Change:
(1)With the rapid changing of socio-economic environment and considering the willingness of the public to participate in the census, the authority continued to adopt the Register and Survey Integrated Census to reduce the burden of the interviewee and interviewer as well as to enhance the data quality. The Census is integrating official registration files and linking these files with the data collected from the sampling survey to compile population and housing census statistics. A total of 15% enumeration areas were sampled to compile the total of the resident population in townships, cities and districts and its detailed statistics. (2)Before 1980, the Census interviewed de facto population, de jure population (includes government employees stationed abroad and their dependents living with them) and foreign population (not include foreign government employees stationed within the border and their dependents living with them). After 1990, the Census only interviewed resident population (de jure population) who have been living or plan to live for 3 months or more either registered or not registered at the household. Based on the Principles and Recommendations for Population and Housing Census of the United Nations, the 2010 and 2020 Census revised the definition of usually living from 3 months to 6 months. (3)There were some differences in the questionnaire items over the historical censuses due to socio-economic changes. Before 1956 only population items are included and housing items are added since the 1966 Census. The 2000, 2010 and 2020 Census, part of the items are linked with official registration files.

5.Data Quality

     *Statistical Methodology and Source Data:
(1)Population for sampling: GIS was used to integrate registered addresses with household registration data to set up digital enumeration areas (each contained 110ˇÓ30 households) which were used as the population for sampling. (2)Sampling methodology: ˇ§Random stratified cluster samplingˇ¨ was adopted for all general survey households. Townships, cities and districts of each county and city as well as indigenous areas were used as the sub-population. The enumeration area was the basic unit of the sampling. The total sampling rate was 15%. Basically the group quarters composed of more than 100 persons or with specific features were fully interviewed by the related authorities. (3)Enumeration method: Enumeration was conducted by multiple ways including personal interview, leave-out/pick-up and Internet. These are arranged and used flexibly by area characteristics. (4)Data were processed mainly by electronic computing system and part by data clerks. (5)Census planning and conduction, statistical results, historical comparison of key items, and statistical analysis are compiled and available for download on the Internet.

     *the Mechanism to Ensure the Reliability and Accuracy:
(1)Statistical tables were compiled based on the questionnaire items. The validation of data among detailed cross-classification tables was performed by electronic computing system with some balanced factors. (2)Related data were collected, and scholars and experts were invited to review the validation of the data.
