Aggregated data is data that has been processed and organized, usually presented in tables.
Survey microdata are raw data obtained from the responses to each question in a survey. It is possible, under certain conditions, to access microdata files from Statistics Canada surveys, in which raw data is anonymized.
It is important to read the metadata and accompanying documentation of surveys, useful for data processing and interpretation of tables generated in statistical software. Both of the following tools offer the possibility to select the variables to download. Microdata are transmitted in .txt format and are accompanied by syntax files in SAS, SPSS or STATA format for purposes of statistical analysis.
In order to facilitate access to survey microdata, the Polytechnique Library is a member of the DLI (Data Liberation Initiative). Our subscription to this service grants access to public microdata, aggregate data tables, and geographic files related to the census.
