Estimates of the number of census families for July 1st, Canada, provinces and territories
Detailed information for July 1, 2017
This estimates program provides annual estimates of the number of census families for Canada, provinces and territories.
Data release - November 8, 2017
This estimates program provides annual estimates of the number of census families for Canada, provinces and territories. Starting in 2006, a new method is used to produce the estimates of census families.
This estimates program is used in the calculation of demographic, social and economic indicators. These estimates are used for planning, program evaluation and base population for various studies.
Reference period: July 1st to June 30th.
- Families, households and housing
- Population and demography
- Population estimates and projections
Data sources and methodology
For the purpose of generating estimates, the definition of family is, with one exception, similar to what is used for the census. As defined up to and including the 2011 Census, a census family can be any of the following:
- a married couple (with or without children of either and/or both spouses);
- a common-law couple (with or without children of either and/or both partners);
- a lone parent of any marital status, with at least one child living in the same dwelling.
The term children refers to blood, step or adopted sons and daughters (regardless of age or marital status) who are living in the same dwelling as their parent(s), as well as grandchildren in households where there are no parents present. Sons and daughters who are living with their married spouse or common-law partner, or with one or more of their own children, are not considered to be members of the census family of their parent(s), even if they are living in the same dwelling. In addition, the sons or daughters who do not live in the same dwelling as their parent(s) are not considered members of the census family of their parent(s). Sons or daughters who study or have a summer job elsewhere but return to live with their parent(s) during the year are considered members of the census family of their parent(s).
The exception resides in how same-sex couples are recognized. While in census, same sex common-law partners are creating a census family, this is not the case for the estimates program before 2006. Starting in 2006, the estimates program has the same definition as the census.
This methodology does not apply.
Data are extracted from administrative files and derived from other Statistics Canada surveys and/or other sources.
These estimates are obtained using data from the census of population counts, adjusted for census net undercoverage (CNU) (record no. 3901). The postcensal estimates are based on 2011 Census.
Data integration is conducted by combining data from multiple sources, including the latest Census, Census coverage studies (Reverse Record Check (RRC)) and administrative data such as the Canada Revenue Agency (CRA), Immigration, Refugees and Citizenship Canada (IRCC)and the U.S. Department of Homeland Security, Office of Immigration Statistics.

This methodology type does not apply to this statistical program.
No imputation was done.
Starting in 2011, postcensal estimates of the number of census families are produced with a three steps methodology: (1) Correction of the T1FF biases using census numbers of family heads; (2) Adjustment of the T1FF data for the reference date using population estimates; (3) Adjustment of the coverage of the census using census coverage studies.
From 2006 to 2010, the estimates are intercensal. They are produced with the same method as the postcensal estimates. Only the parameters of the model change. The correction coefficients and the adjustment for census net undercoverage are linearly interpolated from two consecutive censuses and the population estimates are intercensal.
From 1986 to 2006, the intercensal estimates were the result of a linear interpolation between census counts adjusted for family census net undercoverage.
Three sources of error and bias contribute to the error of closure: (1) the method used; (2) the correction for census net undercoverage; (3) the universes covered.
Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. 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.
Revisions and seasonal adjustment
Data are revised once a year and after each census, postcensal estimates are revised to produce the intercensal estimates.
Demographic estimates are revised using birth, death and interprovincial and international migration statistics when they become available. Revisions may result in notable changes for certain components, particularly for interprovincial migration.
Interprovincial migration data are derived from two sources. Preliminary migration estimates are based on changes of addresses recorded by the Canada child tax benefit program from the Canada Revenue Agency, and are available shortly after the reference month. Final interprovincial migration estimates are based on addresses supplied on personal income tax returns, and are available a year after the reference year.
