What is the Population and Housing Census?

Statistics Korea conducts the Population and Housing Census every five years (i.e., years ending in 0 and 5) to assess the size and characteristics of all people and housing units residing in the Republic of Korea.
According to the United Nations (UN), a population and housing census is defined as the process of collecting, evaluating, analyzing, and disseminating demographic, economic, and social data related to all individuals, households, and dwellings within a country or region at a specific point in time.
Foreign nationals who have lived in the Republic of Korea for more than three months or plan to do so are also obligated to participate in the survey.
All responses are strictly protected under the Statistics Act and will be used solely for statistical purposes.
