Experienced labour force: Persons who, during the week (Sunday to Saturday) prior to Census Day (May 15, 2001), were employed or unemployed who worked for pay or in self-employment since January 1, 2000. The experienced labour force can also be derived by excluding from the labour force those unemployed persons 15 years of age and over who have never worked or who had last worked prior to January 1, 2000 only.

Class of Worker: This variable classifies persons who reported a job into the following categories: (a) persons who worked mainly for wages, salaries, commissions, tips, piece-rates, or payments “in kind” (payments in goods or services rather than money); (b) persons who worked mainly for themselves, with or without paid help, operating a business, farm or professional practice, alone or in partnership; (c) persons who worked without pay in a family business, farm or professional practice owned or operated by a related household member; unpaid family work does not include unpaid housework, unpaid childcare, unpaid care to seniors and volunteer work. The job reported was the one held in the week (Sunday to Saturday) prior to enumeration (May 15, 2001) if the person was employed, or the job of longest duration since January 1, 2000, if the person was not employed during the reference week. Persons with two or more jobs in the reference week were asked to provide information for the job at which they worked the most hours.

Census metropolitan area: Area consisting of one or more adjacent municipalities situated around a major urban core. To form a census metropolitan area, the urban core must have a population of at least 100,000.
