Population and housing censuses by country etc.) are referred to as quinquennial censuses. Others are referred to as decennial censuses. The first quinquennial census was conducted in 1956. For the 2006 Census of Canada, respondents were able to complete their census questionnaire online for the first time. Other options for answering the questionnaire included postal mail (using a pre-paid envelope) and telephone (using an 800 number). At a sub-national level, two provinces (Alberta and Saskatchewan) and two territories (Nunavut and Yukon) have legislation that allows local governments to conduct their own municipal censuses.
