Overview of Spatial and Numeric Data Services
SANDS collects and provides access to aggregate data and Statistics Canada public use microdata files (pumfs).
Pumfs are not complete files, some data has been suppressed to protect confidentiality. Master (complete) microdata files are available through the Prairie Regional Research Data Centre.
Most Canadian aggregate and microdata data is produced by Statistics Canada, derived from surveys. Most aggregate data and pumfs are now freely available, even though SANDS still pays membership fees to the DLI program.
What is aggregate data?
statistics organized into a data structure or database based on tabulations organized by geography, time or social observations. A lot of numeric data can be mapped, ie Census.
What is microdata?
data directly observed or collected from a specific unit of observation, usually an individual, household or family. Microdata files are composed of individual records consisting of a row of numbers, and need processing with statistical software before they are ready for interpretation.
