Transcript

  • 1. DATA SOURCES FOR EC.381 Michael Steeleworthy, MLIS Laurier Data Librarian msteeleworthy@wlu.ca
  • 2. Topics • Data v. Stats • Geographies • Datasets: Canadian and otherwise
  • 3. Data (generallyspeaking…) • A collection of facts used to make decisions or conclusions, or used for calculation • Typically organized so that each observation is a record in a file, and its measured variables are listed as values
  • 4. Statistics (generallyspeaking…) Tabulated output that brings meaning to the collected data In 1910, X people declared themselves as Y “race” in the US Census
  • 5. Datasets can still be difficult to find 1. There is a lot of information out there • The sheer amount of links, resources, and ephemera makes discovering useful resources difficult 2. Data collectors are concerned are privacy • Ask enough questions about a population and you might begin to identify groups or even individuals 3. Data collectors are concerned about quality • Small populations or large geographic ranges can constrain releases 4. Data collectors are concerned about proper use • Incorrect analysis affects everyone 5. The Data does not exist • Not everything under the sun has been collected or analyzed 6. Data Collectors have a profit motive (or have bills to pay) • The license for the data may be cost-prohibitive
  • 6. PUMFs Most of your Canadian datasets will be found in “public use microdata files”; international data have similar names Often only in one format and must be transformed: • CSV • SPSS • Stata • SAS • Excel
  • 7. StatCan Census Geography Where it’s at census / labour / unemployment / education / household spending / social / health / heritage / migration / youth / dependencies / trade
  • 8. StatCan Census Geography Where it’s at
  • 9. STATCAN CENSUS GEOGRAPHY GEORGRAPHY • PROVINCE • CENSUS DIVISION (CD) • REGIONS OR COUNTIES • CENSUS METROPOLITAIN AREA (CMA) • MAJOR URBAN AREAS • CENSUS DIVISION (CD) • MAJOR CITIES • CENSUS TRACT (CT) • NEIGHBOURHOODS, 2500-8000 PPL • URBAN AREAS ONLY • DISSEMINATION AREA (DA) • 400-700 PPL NEIGHBOURHOODS • ALL OF CANADA EXAMPLE WATERLOO REGIONAL MUNICIPALITY
  • 10. STATCAN CENSUS GEOGRAPHY GEORGRAPHY • PROVINCE • CENSUS DIVISION (CD) • REGIONS OR COUNTIES • CENSUS METROPOLITAIN AREA (CMA) • MAJOR URBAN AREAS • CENSUS DIVISION (CD) • MAJOR CITIES • CENSUS TRACT (CT) • NEIGHBOURHOODS, 2500-8000 PPL • URBAN AREAS ONLY • DISSEMINATION AREA (DA) • 400-700 PPL NEIGHBOURHOODS • ALL OF CANADA EXAMPLE URBAN AND SUBURBAN WATERLOO R.M. (i.e., not the rural area)
  • 11. STATCAN CENSUS GEOGRAPHY GEORGRAPHY • PROVINCE • CENSUS DIVISION (CD) • REGIONS OR COUNTIES • CENSUS METROPOLITAIN AREA (CMA) • MAJOR URBAN AREAS • CENSUS DIVISION (CD) • MAJOR CITIES • CENSUS TRACT (CT) • NEIGHBOURHOODS, 2500-8000 PPL • URBAN AREAS ONLY • DISSEMINATION AREA (DA) • 400-700 PPL NEIGHBOURHOODS • ALL OF CANADA EXAMPLE WATERLOO CITY, KITCHENER CITY
  • 12. STATCAN CENSUS GEOGRAPHY GEORGRAPHY • PROVINCE • CENSUS DIVISION (CD) • REGIONS OR COUNTIES • CENSUS METROPOLITAIN AREA (CMA) • MAJOR URBAN AREAS • CENSUS DIVISION (CD) • MAJOR CITIES • CENSUS TRACT (CT) • NEIGHBOURHOODS, 2500-8000 PPL • URBAN AREAS ONLY • DISSEMINATION AREA (DA) • 400-700 PPL NEIGHBOURHOODS • ALL OF CANADA EXAMPLE ALL OF WLU, AREA SOUTH OF BRICKER TO CENTRAL, AREA WEST OF ALBERT
  • 13. STATCAN CENSUS GEOGRAPHY GEORGRAPHY • PROVINCE • CENSUS DIVISION (CD) • REGIONS OR COUNTIES • CENSUS METROPOLITAIN AREA (CMA) • MAJOR URBAN AREAS • CENSUS DIVISION (CD) • MAJOR CITIES • CENSUS TRACT (CT) • NEIGHBOURHOODS, 2500-8000 PPL • URBAN AREAS ONLY • DISSEMINATION AREA (DA) • 400-700 PPL NEIGHBOURHOODS • ALL OF CANADA EXAMPLE WLU AND AREA SOUTH TO CENTRAL ONLY
  • 14. Canada: Statistics Canada • Agency of Federal Government • Produces socio-economic, health, and financial products for governments • Many resources are available to researchers (this means you!) • You will not find the data you need for this course on this site
  • 15. Get Statistics Canada Data through <odesi> • <odesi> • Repository of StatCan datasets and Ipsos polling data (WLU) • You can download entire datasets • Census • Labour • Health • Spending • Youth • Social
  • 16. Get Statistics Canada Data through <odesi> • <odesi> • Repository of StatCan datasets and Ipsos polling data (WLU) • You can download entire datasets • Census • 2006 Individuals File PUMF • 2011 Not ready yet; NHS not ready yet • Labour • Labour Force Survey (LFS) (unemployment) (Monthly) • Survey of Labour Income Dynamics (SLID) (Annual) • Health • Canadian Community Health Survey (CCHS) • CIHI Discharge Abstract Database • Brand New. E-mail me.

  • 18. Why are Canadian resources so old? • Resources • Large county, small population, a lot of work • (StatCan is actually on track for releases from 2011 census) • Fiscal Crisis • StatCan has faced two major cuts since Spring 2012 • Lost staff, lost knowledge base, fewer products • Politics (National Household Survey) • Government of the day, against advice, cut the “Long Form Census” from the 2011 census. • Observations that have collected for decades was not collected in 2011 • The National Household Survey has an adequate sample size for large geographies but not for small regions or small populations
  • 19. United States: census.gov • www.census.gov • Recent Census Data and American Community Survey Data • Data is held in PUMS (public use microdata sample) • Hover over the “Data” tab in the toolbar and choose the census or ACS
  • 20. United States (and int’l) : IPUMS • IPUMS • Repository of US Census and ACS data • Late 1800s to today • Choose your variables and your samples, then download • Registration required, but is free
  • 21. World Bank Microdata Library microdata.worldbank.org • Browsable and searchable index re: • Education • Health • Infrastructure • Finance • Environment • Many nations represented but coverage is spotty • Recommendation: browse surveys instead of searching
  • 22. Social-political Research: ICPSR ICPSR • Largest social-political survey repository • National statistical agencies and research-based surveys • Health • Education • Housing • Spending • Attitudes and Beliefs • Heritage • Dependence • Registration is required but is free

  • 24. UNdata data.un.org • Data portal for all UN Agencies • UNESCO • ILO • IMF • World Bank • World Health Organization • Can search data from all agencies, or link to their respective databases • Recommendation: • Choose a member agency • Surf to its portal • Browse its microdata sets • Coverage can by spotty; mileage will vary
