Saskatchewan

Two marshes near Muscotah and Arrington, Atchison County, northeastern Kansas, yielded a pollen sequence covering the last 25,000 yrs of vegetation development. The earliest pollen spectra are comparable with surface pollen spectra from southern Saskatchewan and southeastern Manitoba and might indicate a rather open vegetation but with some pine, spruce, and birch as the most important tree species, with local stands of alder and willow. This type of vegetation changed about 23,000 yrs ago to a spruce forest, which prevailed in the region until at least 15,000 yrs ago.

This data collection is comprised of a one-in-one-hundred sample of persons who completed the long-form census questionnaire (the one-third sample) for the 1976 Census of Canada. To preserve confidentiality, records for this study were selected from geographic areas with populations of 250,000 or more, including Newfoundland, Nova Scotia, New Brunswick, the Montreal census enumeration area, Quebec, the Toronto census enumeration area, Ontario (excluding Toronto), Manitoba, Saskatchewan, Alberta, the Vancouver census enumeration area, and British Columbia (excluding Vancouver).

The Public Use Sample is a representative sample of individual records from the 1971 Census of Canada 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. To preserve confidentiality, respondents were selected from nine provinces and two Census Metropolitan Areas (CMA) with populations of 250,000 or more. The provinces are Newfoundland, Nova Scotia, New Brunswick, Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia.

To collect data at an international level on the use of medical care and its relation to characteristics of both the population and the prevailing health care systems. Main Topics: Variables Questions covered the following areas: Psychosocial and demographic characteristics, e.g. health related attitudes, family composition, income, education and locus of responsibility for health within the family.
