Note: Broad occupational category A - Management occupations

Census data for occupation groups in Broad occupational category A - Management occupations should be used with caution. Some coding errors were made in assigning the appropriate level of management, e.g., senior manager as opposed to middle manager, and in determining the appropriate area of specialization or activity, e.g., a manager of a health care program in a hospital as opposed to a government manager in health policy administration. Some non-management occupations have also been miscoded to management due to confusion over titles such as program manager and project manager. Data users may wish to use data for management occupations in conjunction with other variables such as Income, Age and Education.

Note: Institutional residents

People in seniors' residences in the 2006 Census are classified as 'not living in an institution'. This is a change from the 2001 Census where they were classified as institutional residents, specifically, 'living in an institution, resident under care or custody'.

Note: Non-permanent residents and the census universe

In the 2006 Census, non-permanent residents are defined as people from another country who, at the time of the census, held a Work or Study Permit, or who were refugee claimants, as well as family members living in Canada with them. In the 1991, 1996 and 2001 censuses, non-permanent residents also included persons who held a Minister's permit; this was discontinued by Citizenship and Immigration Canada prior to the 2006 Census.

From 1991 on, the Census of Population has enumerated both permanent and non-permanent residents of Canada. Prior to 1991, only permanent residents of Canada were included in the census. (The only exception to this occurred in 1941.) Non-permanent residents were considered foreign residents and were not enumerated.

Total population counts, as well as counts for all variables, are affected by this change in the census universe. Users should be especially careful when comparing data from 1991, 1996, 2001 or 2006 with data from previous censuses in geographic areas where there is a concentration of non-permanent residents.

Today in Canada, non-permanent residents make up a significant segment of the population, especially in several census metropolitan areas. Their presence can affect the demand for such government services as health care, schooling, employment programs and language training. The inclusion of non-permanent residents in the census facilitates comparisons with provincial and territorial statistics (marriages, divorces, births and deaths) which include this population. In addition, this inclusion of non-permanent residents brings Canadian practice closer to the United Nations (UN) recommendation that long-term residents (persons living in a country for one year or longer) be enumerated in the census.

Although every attempt has been made to enumerate non-permanent residents, factors such as language difficulties, the reluctance to complete a government form or to understand the need to participate may have affected the enumeration of this population.

For additional information, please refer to the 2006 Census Dictionary, catalogue number 92-566-XWE or 92-566-XPE.

For counts of the non-permanent resident population in 1991, 2001 and 2006, please refer to the 2006 Census table 97-557-XCB2006006.

Note: Occupation

J111 Central Control and Process Operators, Mineral and Metal Processing
J121 Machine Operators, Mineral and Metal Processing

Data for J111 Central Control and Process Operators, Mineral and Metal Processing and J121 Machine Operators, Mineral and Metal Processing should be used with caution. There is some overlap of responses coded to these two groups as respondents do not always provide enough information to allow coders to distinguish between them.

J113 Pulping Control Operators
J142 Pulp Mill Machine Operators

Data for J113 Pulping Control Operators and J142 Pulp Mill Machine Operators should be used with caution. There is some overlap of responses coded to these two groups as respondents do not always provide enough information to allow coders to distinguish between them.

J114 Papermaking and Coating Control Operators
J143 Papermaking and Finishing Machine Operators

Data for J114 Papermaking and Coating Control Operators and J143 Papermaking and Finishing Machine Operators should be used with caution. There is some overlap of responses coded to these two groups as respondents do not always provide enough information to allow coders to distinguish between them.

J191 Machining Tool Operators
J192 Forging Machine Operators
J194 Metalworking Machine Operators
J196 Other Metal Products Machine Operators
J197 Other Products Machine Operators

Census data for these occupation groups should be used with caution. A high number of vague responses related to machine operators in car parts manufacturing has resulted in an over-estimate for occupation group J191 Machining Tool Operators. When compared with 2001 estimates, fluctuations in the data suggest inconsistency in the coding of these occupation groups between 2001 and 2006. In particular, J197 Other Products Machine Operators shows a relatively large decrease between 2001 and 2006. For these reasons, census data users may prefer to make historical comparisons at the three-digit minor group level for these occupations.

Note: Population universe

The population universe of the 2006 Census includes the following groups:
- Canadian citizens (by birth or by naturalization) and landed immigrants with a usual place of residence in Canada;
- Canadian citizens (by birth or by naturalization) and landed immigrants who are abroad, either on a military base or attached to a diplomatic mission;
- Canadian citizens (by birth or by naturalization) and landed immigrants at sea or in port aboard merchant vessels under Canadian registry;
- persons with a usual place of residence in Canada who are claiming refugee status and members of their families living with them;
- persons with a usual place of residence in Canada who hold Study Permits and members of their families living with them;
- persons with a usual place of residence in Canada who hold Work Permits and members of their families living with them.

For census purposes, the last three groups in this list are referred to as 'non-permanent residents'. For further information, refer to the variable Immigration: Non-permanent resident found in the 2006 Census Dictionary, catalogue number 92-566-XWE or 92-566-XPE.
