The DLI Collection is composed of standard products produced by Statistics Canada. The Nesstar data portal consists of two catalogues of Statistics Canada data: Public use microdata files (PUMFS) and Research Data Centre (RDC) master files. Users can search and identify variables of interest on the microdata files and determine whether a PUMF or a master file would best fit their research needs. The metadata in this tool does not represent the complete collection of PUMFs and RDC master files because it takes time to mark up a file using Data Documentation Initiative (DDI) metadata standard and have it placed in the tool.
