Restoration of the 1971 enumeration area polygons for Canada's largest cities

This product contains 23,887 digitally restored 1971 census enumeration area (EA) boundaries for the 33 census metropolitan areas (CMA) defined by the 2011 census. EAs are the smallest geographical unit for the release of 1971 census statistics. These EA boundaries can be aggregated to the census agglomeration (CA) or the CMA level.

The restored EA boundaries also include 1971 population and dwelling statistics. The areas covered by the restored EA polygons account for 61.8% Canada’s total population in 1971.

The purpose of the data set is to provide a historical geography in a digital format. It is intended to be used for reference, mapping and for spatial and time series analyses.

These boundaries were produced by Statistics Canada, Environment, Energy and Transportation Statistic Division in 2017.

The restored 1971 EA boundaries are provided as a single spatial layer. They are also available in Statistics Canada, 2017, “Restoration of the 1971 enumeration area polygons for Canada's largest cities,” Environmental Statistics: Boundary Files, Catalogue no. 16-510-X.
