Census in Hong Kong

Population census in Hong Kong (Chinese: 香港人口普查), a collection of demographic data in Hong Kong, is conducted by the Census and Statistics Department of the Hong Kong Government. The census has been held every ten years since 1961 and the by-census is held between two census. The last census and by-census were in June 2011 and June 2016, respectively.

The census is based on the administrative districts in Hong Kong to find out the characteristics and trends in population. The census is conducted on a large scale and a wide range of data are collected. Statistics collected would be a reference for Hong Kong Government to make policy, or for private organisations for research.

Census and Statistics Ordinance, which was first effective in 1978, is the main law governing the work of the Census and Statistics Department. The Ordinance provides for the taking of a census of population and the collection, compilation and publication of statistical information concerning Hong Kong and for matters connected therewith. It also provides strict safeguards on the confidentiality of data pertaining to individuals or undertakings. For example, CAP. 316 S Census and Statistics (2001 Population Census) Order and CAP. 316 U Census and Statistics (2006 Population Census) Order ordered the Commissioner shall take a census of population in specified period to obtain particulars of persons dwelling in Hong Kong. In particular, Section 4 stated that each person aged 15 or above occupying any premises subject to census shall give to the Commissioner particulars of the matters specified in the Ordinance.

Since 1841, when Hong Kong Island was ceded to the United Kingdom, the government has conducted a census in all villages on the island. The modern census began in 1961, and by-census in 1966 and continues every 10 years.
