Data Files

Core data files include the Canadian Community Healthy Survey (CCHS), the National Longitudinal Survey of Children and Youth (NLSCY), the National Population Health Survey (NPHS), the Census (1991 to 2011), the 2011 National Household Survey and more.  New data sets are regularly released including the Canadian Cancer Registry (CCR) and the Vital Statistics Database (VSD). 

How does a master file differ from a public use microdata file?

The master files in the RDC differ in several ways from the ‘public’ files which are more widely available to the McMaster research community through the Data Liberation Initiative (DLI). For instance, compared to a Public Use Microdata File (PUMF) available through Data & Statistics, a master file will often contain the full sample of respondents (not a sub-set), additional categories in variables such as income, education and ethnicity, lower levels of geography (such as the census tract or dissemination area), discrete values for certain variables (such as age or the exact body weight of a respondent) or other concepts not available in the PUMF. In addition, the master files contain derived variables and bootstrap weights used to calculate variance. RDC access is useful for analytical work when a PUMF may not exist, may not provide access to sensitive variables needed for analysis, or when longitudinal data linkage is required.
