Demographics estimates and dependency ratios by health region and peer groups on July 1, 2021 are now available. Health regions represent administrative areas for health service delivery within a province or territory. Health regions have been grouped into "peer groups" to allow for comparisons of health regions with similar demographic and socioeconomic characteristics.

The estimates released today are based on 2016 Census of Population counts, adjusted for census net undercoverage and incompletely enumerated Indian reserves. To these counts, the population growth estimates for the period from May 10, 2016, to the date of the estimate are added. They are not to be confused with the 2021 Census population counts released on February 9, 2022. Population estimates based on the 2021 Census results for subprovincial areas will be disseminated in early 2024, when census coverage study results will become available.

  Note to readers

This release includes preliminary postcensal population estimates for health region and peer groups by age and sex as of July 1, 2021. Revised estimates as of July 1 for the years 2017 to 2020 are also available. See the Tables tab for more information.

The annual period of reference is comprised between July 1 of a certain year and July 1 of the following year. Therefore, 2020/2021 refers to the period from July 1, 2020 to July 1, 2021.
