  1. GGR 391: Research design Class presentation 30/01/2003 by L. Ruus, Data Library Service <laine.ruus@utoronto.ca>

  2. Outline: • Introduction: • who collects data • data quality considerations • data access • Outline of census geography • Census and other geo-coded data • Spatial information resources

  3. Who collects data about us? • Corporate sector • Marketing and public opinion companies • Banks and credit companies • Magazine and other subscription services • Retailers, including Internet shopping services • Government • Federal government • Provincial government • Municipal government • Academic sector

  4. Government data collection: federal • Health Canada • Environment Canada • Human Resources Development Canada • Statistics Canada • own data collection • data collection for other government institutions under contract (e.g. NLSCY)

  5. Statistics Canada: • Process-produced data (eg. births, deaths, marriages, imports, exports, etc.) • Sample surveys (eg. monthly labour force survey, etc.) • Census of population (100% & 20% samples) • first conducted in 1666 • every 10 years 1871-1951 • every 5 years 1961-2001 (latest)

  6. Data source considerations (quality) Data/statistics: • Source attribution of all data and statistics • Transparency of derived data Collector: • Protection/guarantee of privacy and confidentiality • Changes and corrections • Obligation to publish/inform • Preservation policies

  7. Data dissemination: • Statistics Canada - $$$, selected statistics free But most data/statistics available free via UT/DLS. • Toronto RDC - very restricted • UT/DLS - free, relatively unrestricted • only source for small area data

  8. Data Library Service homepage: <http://www.chass.utoronto.ca/datalib/> Map/GIS Collection homepage: <http://prod.library.utoronto.ca/datalib/maplib/index.html>

  9. Outline of Canadian census geography:

  10. Census and other geocoded data from Statistics Canada

  11. Sources of geo-coded Canadian data: • Canadian census of population: • census subdivision level data 1986-2001 • census tract data 1981-2001 • enumeration/dissemination area data 1981-2001 • Canadian census of agriculture • census agricultural regions, 1981-2001 • Canadian business patterns • census subdivision level data, 2001

  12. Attributes in the population census: • Demographic characteristics: age, sex, marital status • Ethno-cultural and language characteristics • Schooling • Household activities • Labour market activities • Journey to work • Income

  13. Attributes in the population census (cont’d): • Family and household: tenure, shelter costs • Dwelling: type, period of construction, value • More information: Availability of aggregate statistics from the Canadian population census (1666-2001): <http://www.chass.utoronto.ca/datalib/major/censusag.htm>

  14. Outline of Canadian census products: • Nation series/Canadian overview tables • ethnicity (188) x sex (3) x prov/CMA • Dimensions/Special interest series • ethnicity (92) x eg income x prov/CMA • Profile series • ethnicity (100) x CT/EA • Basic cross/summary tabulations • ethnicity (31) x age x CT/EA

  15. Attributes in the Census of agriculture: • Farm type • Land use, tenure, land management • Crops • Livestock & poultry • Farm businesses (eg computer applications)

  16. Attributes in Canadian business patterns: • Number of business establishments • Number of employees (categorical) • Industrial classifications: • NAICS 2-6 digit classification • SIC 1-4 digit classification) • Geography: • province • census metropolitan areas (cities) • census subdivisions (municipalities)

  17. Spatial information resources

  18. Three main types of spatial information resources: • print maps/atlases • aerial photographs (raster images) • digital map files (vector files)

  19. Print maps/atlases: • Listed in UT Libraries catalogue • Available in Map Collection, 5th Floor, Robarts Library • Also listed in individual census web pages at: • Data Library Service homepage • Major research data collections • Canadian data

  20. Aerial photographs: • Paper in Map Collection, 5th Floor, Robarts Library • On-line at: • Map/GIS Collection <http://prod.library.utoronto.ca/datalib/maplib/> • Digital air photos

  21. Digital map files: • Require GIS software to use (e.g. ArcGIS) • Available via UT/DLS census web pages: Aggregate statistics from Canadian population census (1665-2001): <http://www.chass.utoronto.ca/datalib/major/censusag.htm>

  22. In conclusion: • Don’t assume data sources: always check to make sure they do exist! • More Statistics Canada data is available to you free via UT/DLS web pages than via Statistics Canada’s web pages. • Never buy data (numeric or spatial) from Statistics Canada without checking with the Data Library Service first.
