Population Change in Niagara, 1971–2021: Population patterns interpreted

As a result of the Regional Municipality Act of Niagara, Lincoln County and Welland County were merged on Jan. 1, 1970, into the Regional Municipality of Niagara. This Act also merged their 26 subsidiary units into 12 local municipalities: Fort Erie, Grimsby, Lincoln, Niagara Falls, Niagara-on-the-Lake, Pelham, Port Colborne, St. Catharines, Thorold, Wainfleet, Welland, and West Lincoln. These brand-new municipal boundaries were incorporated into Statistics Canada’s enumeration for the 1971 Census of Canada. This paper is a geodemographic analysis of the eleven census years between 1971 and 2021.
