The population, occupied dwelling count, and person per unit calculation of Calgary communities since 1968. <br /><br />These data are collected from different sources and may be based on community boundaries that do not align perfectly with current boundaries. Data from 1968-1977 and 2016-present reflect community boundaries in those years. Data from 1978-2015 are based on the community boundaries in 2016. Where community boundaries have changed substantially over time, this is captured in the "notes" column. Population and dwelling unit totals do not include "Residual Sub Areas", so they may differ slightly from the totals published in official Civic Census records.
