Population density in Canada based on the 2006 and 2011 census data at three levels of geography: census division (CD) (1:5,000,001 and over), census sub-division (CSD) (1:5,000,000 to 1:288,897) and dissemination areas (DA) (1:288,897 and under). Population density is the number of people per square kilometer. Population density change measures the rate of change calculated by the difference in total population density values for each area between 2006 and 2011, divided by the total population density of 2006. The CD and CSD boundaries are based on 2011 data. The 2006 population figures have been adjusted accordingly. The DA boundaries are based on 2006 data. All areas with no data are indicated with a value of -999.
