Data sources and methodology
This is a sample survey with a cross-sectional design.
For the 1987 survey, data were collected from all corporations with assets greater than or equal to $25 million, as well as for corporations in strata where the number of corporations was less than or equal to 8. For the remaining population, a sample was selected using a modified "Neyman" allocation technique on both sales and assets of corporations from the previous year's file. The sampling fractions so determined were then used to select the 1987 sample. The number of corporations thus selected was a function of the sampling rate, the size of the 1987 population and the sample selection cut-off date. The sampling rate was generally not less than one in 40 in each stratum.
Errors may occur in almost every phase of a statistical operation. Analysts may misunderstand transcription instructions, selected T2 returns may not be available for transcription and some inconsistencies may be missed by the edit procedure. All such errors may be missed by the edit procedure. All such errors are called 'non-sampling errors'. Some of the non-sampling errors usually balance out over a large number of observations. However, other errors may run systematically in only one direction, resulting in a bias in the estimates. No quantifiable measures of reliability of the estimates are available, however the sample generally accounts for over 80% of total assets, 65% of total revenue and 70% of total pre-tax profits.
To produce industry and national estimates, a separate ratio estimation system was employed. The ratio estimation procedure utilized such major financial items as assets, equity, sales, profits and taxable income, which had been tabulated on a universe basis to estimate the remaining financial items of the non-sample corporation. Prior to estimation, both the sample and population data were edited to identify inconsistencies and corporations which deviated drastically from the expected norm. However, the sheer size of the corporate population as well as its nature precluded the edit process from being exhaustive. For this reason, preliminary tabulations were further scrutinized for inconsistencies using industry knowledge and historical data.
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.
