Detailed information for 1991





Record number:


The objectives of this survey were to: measure the frequency and number of job changes occurring in the Canadian labour market over one-, two- and three-year periods; provide information on the characteristics of jobs held (wage rates, usual work schedules, etc.); identify groups of people who would benefit from EIC programs; and identify participants of specific EIC programs.

Data sources and methodology

Target population

The Canadian non-institutionalized population aged 16 to 69, excluding persons living in the Yukon, the Northwest Territories and persons living on Indian Reserves.


This is a sample survey with a cross-sectional design.

Data sources

Responding to this survey is voluntary.

Data are collected directly from survey respondents.

This is a supplement to the Labour Force Survey (SDDS ID 3701). The survey collects retrospective information for a 12 month period in an initial interview and combines this information with information for a second 12 month period collected in a subsequent interview conducted 12 months later.


Identical calculation of weights as in the Labour Force Survey (LFS) (SDDS ID 3701) with 3 exceptions: 1) An adjustment to account for the use of five-sixth subsample, instead of full LFS sample; 2) An adjustment to account for the additional non-response to the Labour Market Activity Survey (LMAS) for households which do respond to the LFS or for which previous month's LFS data is brought foreward; 3) A re-adjustment to account for independent province-age-sex projections, after the above adjustments are made. Adjustments 1 and 2 above are taken into account by multiplying the LFS sub-weight (i.e. the weight resulting from the first four LFS weighting factors) for each responding LMAS record by: the sum of LFS sub-weights of households considered responding to LFS divided by the sum of LFS sub-weights of households considered responding to LMAS.

Disclosure control

Statistics Canada is prohibited by law from releasing any information it collects that 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.

In order to prevent any data disclosure, confidentiality analysis is done using the Statistics Canada Generalized Disclosure Control System (G-Confid). G-Confid is used for primary suppression (direct disclosure) as well as for secondary suppression (residual disclosure). Direct disclosure occurs when the value in a tabulation cell is composed of or dominated by few enterprises while residual disclosure occurs when confidential information can be derived indirectly by piecing together information from different sources or data series.
