Language used most often at work of person 15 years or over

Status: This standard was approved as a departmental standard on April 20, 2009.


Language used most often at work refers to the language the person uses most often at work. A person can report more than one language as "used most often at work" if the languages are used equally often.

Person 15 years or over refers to an individual whose age is 15 years or over.


'Language used most often at work' applies to non-institutional residents who worked at some point in the reference period.

For the census, it usually relates to the job the person held in the week prior to enumeration. However, if the person did not work during that week but had worked at some time since January 1 of the prior year, the information relates to the job held longest during that period.

'Language used most often at work' may also be collected for other jobs, depending on the objective of the survey. However, for it to be collected, a person must be associated with a job, current or past.

In using the Classification of language(s) of person in this context, the category, "none", is not used.

Conformity to relevant internationally recognized standards

The classification of languages is based on the international standard ISO 639 presented in the Ethnologue, using those categories that are applicable to the Canadian population and adding supplementary detail on Aboriginal languages spoken in Canada.
