Notes: Built-up area for 1971 is based on Canada Land Inventory: Land Use (CLI: LU), with modeling of roads. Canada Land Use Monitoring Program (CLUMP) data exclude the CMAs of Moncton, Trois-Rivières, Sherbrooke, Peterborough, Kingston, Barrie, Brantford, Kelowna and Abbotsford–Mission. As a result, 1971 built-up areas may be underestimated for these CMAs. CLI: LU built-up areas that were not built-up in the AAFC Land Use,1990 dataset were removed from the 1971 built-up data and reclassified according to their 1990 cover. Built-up areas for other years are taken from Land Use, 1990, 2000 and 2010. Arable land is composed of the cropland, tame or seeded pasture and summerfallow land from the Interpolated Census of Agriculture. Natural and semi-natural land is the residual area remaining after subtracting built-up and arable land from the total area. Because it was calculated residually, the class also includes some homes and other buildings, particularly those located on large lots and in rural areas, since these may not be captured by satellite imagery as built-up, due in part to the resolution of the data, but also overlying tree canopy. For 2011, forest and water are broken out separately based on data from AAFC Crop Inventory, 2011 and CanVec+ respectively. Other natural and semi-natural land is a residual class calculated by subtracting all other classes from the total area.
