Workshop Objectives

Understanding what you can find using historical Census publications

Learning the key changes to Census publications over time

o once a month?o once a term?o never…o or do you use the digitized

version?

Agenda

1. Introduction

2. Census changes

3. Scope of Census statistical publications

4. Sources of Census statistics and …reference materials

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

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!

Censuses to 1901● 1666-1872 - Colonial censuses, starting with New France, 1666.

Age, sex, language, occupation, housing and other property... - More info [Link]

● 1765... - Questions introduced on race, religion and ethnic origin

● 1871 - First national Census - under 1867 BNA (representation by population) - NB, NS, QC and ON - included aboriginal persons - questionnaires, called schedules, were administered by

enumerators - Census Dictionary appendix A traces Census questions and derived variables since Confederation (when Census questions were first asked)

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

What are Profiles?● Univariate* overviews of geographic areas,

Two types of Profile tables:Thematic &Cumulative profiles

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:

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)

• 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)

How to explore the digitized volumes… an overview

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

Workshop topics

2. Census changes

3. Scope of Census statistical publications

4. Sources of Census statistics and … reference materials

We are here

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

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

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

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■ Statistics Canada 2006-Preview | 2001 | 1996 > See

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

Doumentation > Products

○ Use series/title information from above with Statistics Canada library catalogue [Link]

(B) Navigating the Census information: the earlier Population Censuses

1665 - 1871

● Queen’s University Library web site | Bilingual access: DLI/EFT
