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.

Industry (based on the 1997 North American Industry Classification System): Refers to the general nature of the business carried out in the establishment where the person worked. If the person did not have a job during the week (Sunday to Saturday) prior to enumeration (May 15, 2001), the data relate to the job of longest duration since January 1, 2000. Persons with two or more jobs were required to report the information for the job at which they worked the most hours. The 2001 industry data are produced according to the 1997 NAICS. The NAICS provides enhanced industry comparability among the three North American Free Trade Agreement (NAFTA) trading partners (Canada, United States and Mexico). This classification consists of a systematic and comprehensive arrangement of industries structured into 20 sectors, 99 subsectors and 300 industry groups. The criteria used to create these categories are similarity of input structures, labour skills or production processes used by the establishment. For further information on the classification, see North American Industry Classification System, Canada, 1997, Catalogue No. 12 501 XPE. The variable “Industry (based on the 1997 NAICS)” does not permit direct comparison to any previous census industry data. The 1980 Standard Industrial Classification should be used for comparisons between the 1986, 1991, 1996 and 2001 Censuses.
