Guide to the Census of Population, 2016
Chapter 11 – Dissemination
A primary goal of the Census of Population dissemination process is to ensure that census and geography products and services meet the primary needs of the majority of data users. Similar to previous Census of Population releases, Statistics Canada strives to provide more data free of charge to the public, while at the same time seeking ways of publishing census results in a timely and user-friendly manner. The first 2016 Census of Population results were made available to data users on February 8, 2017. All major releases of standard products were scheduled to take place in 2017, 10 months earlier than in 2011.
How census data are used
Governments, businesses, associations, community organizations and many others use census data extensively. The following are some examples:
- The federal government uses population counts from the decennial census (held in years ending in the number 1, for example, 2001, 2011) to realign the boundaries of federal electoral districts. These data are required under the Constitution Act, 1867, and ensure equal representation of the population in the House of Commons.
- Data from the decennial and quinquennial censuses are used to produce population estimates.
- These estimates are used in the calculation of transfer payments from the federal government to the provinces and territories, and from the provincial and territorial governments to municipalities.
- In 2016/2017, the Government of Canada projects allocating roughly 68 billion dollars to provincial and territorial governments through its major transfers (Canada Health Transfer [CHT], Canada Social Transfer [CST], Equalization and Territorial Formula Financing [TFF]) and direct targeted support. Even a small error in the estimates could lead to the misallocation of billions of dollars.
- Government departments need to know the age trends of the population to estimate future demands for child tax benefits and old age pensions.
- Communities use census information on population growth and movement for planning services such as schools, daycare, police services and fire protection.
- Town planners, social welfare workers and other government agencies use census information on families.
- Transportation planners for provincial, territorial, regional and municipal governments use census information to analyze traffic flows, assess existing transportation services and plan for changes to these services and to road networks.
- Life insurance companies base their premium tables on census age data.
- Businesses determine new factory, store and office locations based largely on the size and distribution of the population in different areas.
- Manufacturers of household and farm equipment are guided by census data in determining the best market locations for their products. They can also assess the benefits of developing specific products by knowing the characteristics of the population in particular areas.
Overview of 2016 Census of Population products and services
Products and services from the 2011 Census Program were evaluated for their continued usefulness and relevance in 2016.
The 2016 Census of Population products and services are meant to:
- satisfy policy and market analysis data needs

Connecting with Canadians
Statistics Canada continues to use new media to provide access to relevant, accurate and timely statistical information and to foster engagement, cooperation and information-sharing among people who use statistical information. For 2016, the Census of Population is again engaging with the public through Facebook, Twitter and YouTube, and during chat with an expert sessions. A list of the different initiatives can be found on the Stay connected page.

Published census data go through a variety of automated and manual processes to determine whether the data need to be suppressed. This is done primarily for two reasons: (1) to ensure that the identity and characteristics of respondents is not disclosed (which will subsequently be referred to as confidentiality) and (2) to limit the dissemination of data of unacceptable quality (which will subsequently be referred to as data quality).
Overview of suppression for confidentiality reasons
Confidentiality refers to the assurance that Statistics Canada will not disclose any information that could identify respondents. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data. Consequently, geographic areas with a population below a certain threshold are not published.
All counts in census tabulations undergo random rounding, a process that transforms all raw counts into randomly rounded counts. This reduces the possibility of identifying individuals in the tabulations.
The risk of direct or residual disclosure must also be addressed when determining product content. A number of factors must be considered when assessing the risk of disclosure. The detail of individual variables, cross-classification of variables and the geographic level of the data will all contribute to the level of risk. For example, there may be no risk in producing tables with the number of persons in the dwelling and detailed groupings of age by various characteristics of the household members for large geographic areas. However, the risk of disclosure would increase for lower levels of geography.
Area suppression for standard and non-standard geographic areas
Area suppression is used to remove all characteristic data for geographic areas whose population size is below a certain threshold. The population size threshold for all standard areas or aggregations of standard areas is 40, except for blocks, blockfaces and postal code-defined areas. Consequently, no characteristics or tabulated data are released if the total population of the area is less than 40. However, for six-character postal code areas, areas built from the block or blockface, the population size threshold is 100. These population size thresholds are applied to 2016 Census data as well as to all previous census data.
