Authors: Alex Guindon and Susan Mowers
3. • How often do you use
the print volumes of
the historical Census?
o once a month?
o once a term?
o never…
o or do you use the digitized
version?
4. Agenda
1. Introduction
2. Census changes
3. Scope of Census statistical publications
4. Sources of Census statistics and
…reference materials
5. Why do we need a workshop on
Historical Census resources?
• Increasing lack of familiarity with researching historical
Census statistics
• Census – to – Census variations
• Changes in use patterns
• Recent digitization of print volumes

7. Censuses to the early 1900’s
.
Population Census
Parallel censuses:
- recent deaths
- farms; livestock; farm products;
- real estate
- fur & fabric products
- forestry products
- shipping and fisheries
- mining products
- industry, etc.
Many families would have been
enumerated in several censuses
No wonder Censuses were
only held once every
10 years!
8. Censuses to 1901
● 1666-1872 - Colonial censuses, starting with New France, 1666. Age, sex,
language, occupation, housing and other property... - More info [Link]

11. Two major Census
statistical publications
Profiles Tabulations
(Simple variable tables)
• Major component of the print
Census publications
• Electronic formats, e.g.,
online Community Profiles
or Census Profile...
• Many distribution channels:
Census Analyser, Profile
series via DLI and the public
web site, former E-Stat (now
DLI and Queen’s).
(Allow cross-tabulations of two +
variables)
Various names and distribution
channels via Statistics Canada:
• detailed tables through DLI:
Topic-based Tabulations,
former Basic Summary Tables,
and former Dimension Series
• simpler Topic-based
tabulations through Statistics
Canada web site,
• simpler Nation Series &
Dimension Series (both
replaced by the Topic-based
tabulations) via the Depository
Services Program
12. What are Profiles?
● Univariate* overviews of geographic areas,

tables:
Thematic &
Cumulative profiles
13. What are Census (cross)tabulations?
● Multivariate tables by region
● Detailed subject matter
● Use Topic-based tabulations to tabulate two or more characteristics
yourself, e.g., Education-Immigration-Sex table 97-562-XCB200601:
SOURCE: Statistics Canada. 2009. Occupation - National Occupational Classification for Statistics 2006 (720), Class of Worker (6) and Sex (3)
for the Labour Force 15 Years and Over of Canada, Provinces, Territories, Census Metropolitan Areas and Census Agglomerations, 2006 Census
- 20% Sample Data, Topic-based Tabulation: Labour, Occupation. Retrieved from http://www12.statcan.gc.ca/census-recensement/2006/dp-
pd/tbt/index-eng.cfm
14. Evolution of the
Census tabulation series
● Going back in time to 1996, the greater in number and depth
of the electronic tables (DSP/Web + DLI).
● 1996- 2006 Censuses:
● multiple tabulation series and
● geography goes down to dissemination areas and census tracts
● 2011 National Household Survey Data Tables (like the former
20% Census)
● 2011 Census Topic-based tabulations (like the 100% / short-
form Census)

21. Pre-Confederation Censuses:
1665-1871
• From the print: Censuses of Canada, 1665 to 1871, Statistics of
Canada, Volume IV
• 343 tables in Beyond 20/20 viewer format
• Formerly on E-Stat, now available through Queen’s University Library web site
(in English)
• By region and date
• The tables also available via DLI/EFT under census_pop_recens (in English and
French)
Nova Scotia
Prince Edward Island

22. Digitized Print Volumes of the
Census of Canada
Databases of nomimal censuses (1825 to 1921)
• LAC
• Ancestry.ca
Canadiana: 1851-1891
Internet Archive (archive.org): 1851-1991
• Complete volumes
• Reference materials
• PDFs are searchable (OCRed) and downloadable
23. How to explore the digitized volumes
… an overview
• UofT guide to the Census aggregate statistics
o Detailed breakdown by product and geographic level
o Digitized catalogue of products (when available)
o Digitized tables of contents
o Extensive historical coverage
• Questionnaires and schedules (University of Ottawa)
• Canadian census questions and derived variables since
confederation
(from Appendix A of the 2011 Census Dictionary)
Internet Archive -- Advanced Search
- Under collection select: statisticscanada
- In any field:[census year] AND [topic]
Example: 1981 census immigra*
- Keyword search in the PDFs
24. DEMONSTRATION
Question:
What are the top countries for place of birth of
immigrants?
• In the 1981 census
• In the 1951 census
Answering this question shows that:
• It is possible to retrieve a lot of information from old
censuses
• but it may not be immediately comparable to
statistics from recent censuses
25. Workshop topics

26. Reference materials …
● To provide background on the Census questions asked …
○ Topical information and finding tools
● To navigate the printed Census tables whether print or
digitized formats
27. Reference Materials
(A) Researching by topic: after Confederation
● "Census questions and derived variables since Confederation” in Census
Dictionary Appendix A … ”when”
● Questionnaires 1871-2006 uO Library | 1871-1961: CCRI *Canadian
Century Research Infrastructure
● Search the Statistics Canada Library catalogue [Link]
■ Search by series (e.g., Census and optional year) and keyword (your
topic) searches
● add series keywords, e.g., Nation or Population or Bulletin
■ Records often have links to the Internet archive version
■ Note the title of the publication or the Statistics Canada catalogue
number … important because the titles of the publications do not often
indicate the topic, and because many topical tables are outside the
“Population” volumes
● Also search Internet Archive [Link] e.g., title keyword: Census and (Year)
and collection is: statisticscanada
28. Reference Materials
(A) Researching by topic: before Confederation
Approximately 1821-1871
● Library and Archives Canada, > About the 1871 Census :
Column headings and interpretation (“about” the questions on the
Census schedules)
● Manuals containing the Census Act and Instructions to enumerators
[Internet archive search of Census manuals] and on CCRI
29. Reference Materials
(B) Navigating the Census by year
The Census publications grew substantially over time, making manual browsing
through the print volumes increasingly laborious …
● 1961-2006
○ Products and Services catalogues essential to understanding Census
publications

reference products
■ U of T – [Link] > See individual Census years > Doumentation >
