Spatial Data Infrastructure (SDI)


The Spatial Data Infrastructure (SDI) is a repository of integrated spatial and tabular datasets that together form the geographic framework for all of Statistics Canada's data collection and dissemination activities. It is both an internal maintenance database and a data archive whose primary purpose is to facilitate the generation of geographic data products. It contains vintages of the National Geographic Database (NGD), administrative and statistical geographic areas, cartographic support datasets, geocoding support datasets, field collection activity data files, population and dwelling count variables, and other datasets integral to Statistics Canada operations requiring a spatial component.

For more information on Spatial Data Infrastructure, consult the Dictionary, Census of Population, 2021.
