description: &lt;p&gt;In 1991, the National Task Force on Health Information cited a number of issues and problems with the health information system. To respond to these issues, the Canadian Institute for Health Information (CIHI), Statistics Canada and Health Canada joined forces to create a Health Information Roadmap. From this mandate, the Canadian Community Health Survey (CCHS) was conceived.&lt;/p&gt;

&lt;p&gt;The CCHS is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population. The survey is offered in both official languages. It relies upon a large sample of respondents and is designed to provide reliable estimates at the health region level every 2 years.&lt;/p&gt;

&lt;p&gt;The CCHS has the following objectives:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;Support health surveillance programs by providing health data at the national, provincial and intra-provincial levels&lt;/li&gt;
&lt;li&gt;Provide a single data source for health research on small populations and rare characteristics&lt;/li&gt;
&lt;li&gt;Timely release of information easily accessible to a diverse community of users&lt;/li&gt;
&lt;li&gt;Create a flexible survey instrument that includes a rapid response option to address emerging issues related to the health of the population&lt;/li&gt;&lt;/ul&gt;

&lt;p&gt;The CCHS produces an annual microdata file and a file combining two years of data. The CCHS collection years with both consistent design and consistent population representation can also be combined by users to examine populations or rare characteristics.&lt;/p&gt;

&lt;p&gt;The primary use of the CCHS data is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information collected from respondents to monitor, plan, implement and evaluate programs to improve the health of Canadians. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the CCHS results to raise awareness about health, an issue of concern to all Canadians.&lt;/p&gt;

description: The survey began collecting data in 2001 and was repeated every two years until 2005. Starting in 2007, data for the Canadian Community Health Survey (CCHS) were collected annually instead of every two years. While a sample of approximately 130,000 respondents were interviewed during the reference periods of 2001, 2003 and 2005, the sample size was changed to 65,000 respondents each year starting in 2007.

The CCHS has undergone two major redesigns. The first in 2015 reviewed the sampling methodology, adopted a new sample frame, modernized and updated its health content, and reviewed the target population. The second in 2022, further reviewed and updated the content of the survey as well as transitioned it to an online electronic questionnaire (EQ) that was available for direct self reporting by selected respondents. Consultations were held with federal, provincial and territorial share partners, health region authorities and academics for both redesigns. As a result of these redesigns and major changes to collection and sampling approaches as well as content updates, caution should be taken when comparing data from previous cycles to data released for the 2015 and 2021 and for data released 2022 and onwards.
