ECONOMIC REGION

An economic region (ER) is a standard geographic unit for analysis of regional economic activity.

ERs are represented by a two-digit code (which is preceded by the PR code).

Nova Scotia has five economic regions (ER).

CENSUS DIVISION

Other than provinces and territories, census divisions (CD) are the most stable administrative geographic areas. They are often used in longitudinal analyses.

CDs are also represented by a two-digit code (which is preceded by the PR code).

CENSUS DIVISION

Nova Scotia has 18 census divisions (CD), which, in NS, are also called ’counties’.

QUIZ ANSWERS

CENSUS SUBDIVISION

Census subdivision (CSD) is the general term for a municipality (as determined by provincial/territorial legislation) or for areas treated as municipal equivalents for statistical purposes (e.g., reserves).

Nova Scotia has 96 Census Subdivisions:26 are classified as Indian Reserves (IRI), 12 as Municipal Districts (MD), 3 as Regional Municipalities (RGM), 28 as Subdivisions of County Municipalities (SC), and 27 as Towns (T).

CENSUS SUBDIVISION

CSDs are represented by a seven-digit code which consists of the PR code followed by the CD code and a three-digit CSD code.

The Halifax Regional Municipality is represented by CSD 1209034, which breaks down into the two-digit PR code for Nova Scotia (12), the two-digit CD code for Halifax County (09), and the CSD code for the HRM (034).

1209034

QUICK QUIZ

What is the CSD code for North

Rustico, PEI?

Has the population increased or

decreased between 2011 and 2016?

QUIZ ANSWERS

AGGREGATE DISSEMINATION AREA

New in 2016: Aggregate dissemination areas (ADA) cover the entire country and, where possible, have a population between 5,000 and 15,000 based on the previous census population counts.

ADAs are represented by an eight-digit code which consists of the PR code followed by the CD code and a four-digit ADA code.

AGGREGATE DISSEMINATION

AREA

Halifax County has 57 ADAs.

Mount Saint Vincent University is located in ADA 12090057, which breaks down into the two-digit PR code for Nova Scotia (12), the two-digit CD code for Halifax County (09), and the ADA code for the area in which MSVU is located (0057).

12090057

DISSEMINATION AREA

A dissemination area (DA) is a small, relatively stable geographic unit with an average population of 400 to 700 persons. It is the smallest standard geographic area for which all census data are disseminated.

Dissemination area boundaries follow roads. DA boundaries may follow other features (such as railways, water features, power transmission lines), where these features form part of the boundaries of census subdivisions or census tracts.

DISSEMINATION AREA

Nova Scotia has 1658 Dissemination Areas, while Halifax County (1209) has 601 DAs.

Mount Saint Vincent University is located in DA 12090574; this breaks down into the two-digit PR code for Nova Scotia (12), the two-digit CD code for Halifax County (09), and the DA code for the area in which MSVU is located (0574).

QUICK QUIZ

What is the 2016 population of DA

12090574?

Why is there no data for 2011?

QUIZ ANSWERS

CENSUS METROPOLITAN AREA / CENSUS

AGGLOMERATION

A census metropolitan area (CMA) or a census agglomeration (CA) is formed by one or more adjacent municipalities centred on a population centre (known as the core).

A CMA must have a total population of at least 100,000 of which 50,000 or more must live in the core. A CA must have a core population of at least 10,000.

CENSUS METROPOLITAN AREA / CENSUS

AGGLOMERATION

Nova Scotia has five CMA / CAs.

Halifax (CMA): 12205

Kentville (CA): 12210

Truro (CA): 12215

New Glasgow (CA): 12220

Cape Breton (CA): 12225

12205

CENSUS TRACT

Census tracts are subdivisions of CMAs and CAs. They are small and relatively stable geographic areas that generally have a population of less than 10,000 people. If the population of a CT exceeds 10,000, it is split in the next census.

CTs are located in CMAs or CAs with a core population of 50,000 or more in the previous census. CTs remain even when thecore population drops below 50,000.

CENSUS TRACT

Halifax is the only area in NS that has CTs, containing 98 in total.

Each census tract is assigned a seven-character numeric "name”, which includes leading zeros, a decimal point, and trailing zeros.

The three-digit CMA/CA code must precede the CT "name” (but not the PR code)

WHAT IS CHASS?

CHASS DATA CENTRE

CENSUS ANALYSER @ CHASS

• Includes profile files at enumeration areas, census tracts, census divisions, census subdivisions, federal electoral districts or provincials levels; some data going back to 1961

• Public use microdata from 1971 to latest CENSUS via SDA software (Survey Documentation and Analysis

• Postal code conversion files for the 2006, 2001 and 1996 CENSUS data

• Import and use the data with analytical or GIS mapping software

• Bilingual

This collection of on-line databases and custom built search and retrieval programs are maintained by Computing in the Humanities and Social Sciences (CHASS) at the University of Toronto.

CHASS DATA CENTRE

CANSIM @ CHASS(YES , THAT ’S WHAT THEY ’RE C ALL ING I T )

• Search by text, table number or time series number

• Browse by subject, survey number, table titles and labels or by Statistics Canada's keywords classification for tables

• Various download formats

• Historical versions of CANSIM (available only at CHASS)

• Bilingual



CHASS DATA CENTRE

SURVEY DOCUMENTATION & ANALYSIS (SDA) @ CHASSThe UT/DLS service provides access to hundreds of survey and census data sets and documentation.

SDA is a series of software programs that:

• presents documentation associated with survey data sets

• facilitates Web-based analysis of survey data

• includes procedures for creating customized subsets of data that can be downloaded for use in Excel and other statistical software packages.



CENSUS ANALYSER

• no cross tabulations, only tables

• codebook is not as good as SDA

• smaller levels of geography are available, all the way down to the dissemination area (DA).

• can create cross tabulations

• codebook is easily searchable

• the smallest level of geography is at the level of the province (PR) or the census metropolitan / census agglomeration (CMA/CA).
