Nordicity is the degree of northerness. The term is most often used by the Canadian government that has a set system for measuring nordicity. This is based on ten variables including temperature, latitude, population density. This system is used for determining a number of regulations in fields such as environmental protection, infrastructure, and many others. Canada's north is normally divided into three areas. The middle north covering the northern parts of most provinces, as well as parts of the territories is largely populated by those of European decent and has significant resource extraction if a low population. The far north covers the northern part of the continent the southern Arctic Archipelago. The extreme north covers the northern most islands and is largely uninhabitable. Other countries have their own systems of measuring nordicity.

The idea of nordicity and the changing conceptions of what is the north has also recently become a subject for historians.
