Abacus Data Repository This link opens in a new windowAbacus is a data repository that holds the collection of research data sets of UBC libraries, other BC research libraries and organizations from around the world. Data sources include public use microdata files (PUMFS) from censuses, other social and health surveys, public opinion polls, and geospatial data for GIS. There are datasets specific to the lower mainland and Canada more generally. Access to some datasets is restricted and requires you to login using your CWL.
