Definitions, data sources and methods

As part of a website improvement initiative, a new Standards, data sources and methods page has been launched.

Along with improved navigation and more in-depth information on data standards, other features will be introduced over the next few months to further enhance user experience. Please visit the new page and then share your feedback by completing a short feedback form.

The purpose of the site is to provide information that will assist in the interpretation of Statistics Canada's published data. The information (also known as metadata) is provided to ensure an understanding of the basic concepts that define the data including variables and classifications; of the underlying methodology of our surveys; and of key aspects of the data quality. It also provides direct access to questionnaires.
