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. National population censuses are carried out in Chile every ten years by the
Melville Island (Northwest Territories and Nunavut) meridian and form part of the Northwest Territories. These can only be reached by land from Nunavut or boat from the Northwest Territories. The island has little or no vegetation. Where continuous vegetation occurs, it usually consists of hummocks of mosses, lichens, grasses, and sedges. The only woody species, the dwarf willow, grows as a dense twisted mat crawling along the ground. However, a diverse animal population exists: polar bear, Peary caribou, muskox, northern collared lemming, Arctic wolf, Arctic fox, Arctic hare, and ermine (stoat) are common.
