How many times has the Population and Housing Census been conducted? What is the legal basis of the census?
The first census was launched in 1904 in Taiwan area. It had been conducted seven times before the government relocated to Taiwan. The first one was carried out in 1956 after the government relocated to Taiwan. The first four censuses were conducted in accordance with the Household Registration Law and the Population Census Law by the Ministry of Interior in conjunction with the Population Census Office of the Executive Yuan. However, the responsibility of conducting the fifth census in 2000 was transferred to the Department of Census, Directorate-General of Budget, Accounting and Statistics (DGBAS), Executive Yuan due to the amendment and abandonment of the afore mentioned laws. In accordance with the Statistics Act, the census should be conducted decennially. 2010 Population and Housing Census was the sixth census and was carried out by integrating official registration files and linking these files with the data collected from the sampling survey to compile population and housing census statistics, known as Register and Sample-Assisted Census. A total of 16% enumeration areas were sampled and each household and person in these areas was visited. All enumeration was completed before January 22 of 2011. The Chinese title of the Department of Census, Directorate-General of Budget, Accounting and Statistics (DGBAS), Executive Yuan was renamed due to the reorganization of the government in February of 2012.
