Canadian Community Health Survey: Combined data, 2017 and 2018

Released: 2019-10-22

Combined data for the 2017 and 2018 reference years are now available from the Canadian Community Health Survey.

  Note to readers

The 2017/2018 reference period for the Canadian Community Health Survey (CCHS) represents the average population aged 12 and older over the two-year period. The CCHS is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population. Data were collected from approximately 110,000 respondents over the two years.

The CCHS produces an annual microdata file and a second microdata file combining two years of data, every second year. The combined data are the same as the two individual annual data files, but also contain data for Yukon, the Northwest Territories, and Nunavut. The two-year data can be used to disaggregate estimates to represent smaller populations and rare characteristics. The annual data for 2018 were released in The Daily on June 25, 2019.

Residents of Indian reserves are excluded from the survey's coverage. Therefore, numbers reflect First Nations people living off reserve, Métis and Inuit. Other exclusions are health care institutions, some remote areas, and full-time members of the Canadian Forces (living on or off military bases).

The data are now available in the Research Data Centres.


The fact sheet "Quick facts by census metropolitan area, 2017-2018," which features a selection of health indicators for the 36 census metropolitan areas in Canada, is now available as part of the series Health Fact Sheets (Catalogue number82-625-X).
