Census of Canada, 1971

The Public Use Sample is a representative sample of individual records from the 1971 Census Master File. The primary sample size is one-in-one-hundred and the sample is self-weighting. Data from the long form questionnaire, or one-third sample, were used to create these microdata files. There are six files: for each of the 2 levels, provincial and CMA, there are 3 datafiles organized by individual-, household-, and family-units. The Individual Files contain 58 variables for 214,019 cases at the provincial level and 53,713 cases at the CMA level. Both files have logical record lengths of 99 characters. The Household Files contain 65 variables and have logical record lengths of 91 characters. There are 59,997 cases in the provincial file and 15,801 cases in the CMA file. The Family Files have 64 variables for 50,219 provincial level cases and 12,923 CMA level cases. Both files have logical record lengths of 139 characters.
