This animated map shows change in population density over the past 100 years. The mapped data has been generalised to better display the broad patterns in population settlement in Canada. This data is not recommended for display at scales greater that 1:25,000,000.

The historic changes in boundaries influence some of the changes in patterns observed in the animated map. The effect of the changes in boundaries has the most influence in data displayed for the lowest population density class, particularly for the years 1901 - 1951. In some cases, areas mapped in one year do not appear in subsequent years because the population density has dropped below the class threshold.
