(Apr. 1, 2009) On January 20, 2009, Switzerland promulgated a Census Regulation that became effective on February 1 (Volkszählungsverordnung, Dec. 19, 2008, Amtliche Sammlung des Bundesrechts 241 (2009), available at http://www.admin.ch/ch/d/as/2009/index0_3.html (click on page 241)). The Census Regulation implements the Census Act of 2007 (Volkszählungsgesetz, June 22, 2007, Systematische Sammlung des Bundesrechts No. 431.112, available at http://www.admin.ch/ch/d/sr/43.html#431.112 (click on No. 431.112)). The new census system will first be employed in 2010.
The Census Act and the Census Regulation abolish the traditional ten-year census that involved the surveying of the entire population. Instead, statistical data will now be compiled annually or even more often, on matters relating to population, households, employment, health and social matters, education, migration, culture and religion, traffic and the environment, and dwellings. The data will be gathered primarily from existing registers of the population, such as the registers of residence of the local communities, the cantons, and the federation. In addition, representative sampling will be employed.
