Data sources and methodology

Sampling

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

Base-weighted indexes which measure price changes over time for a selection of principal commodities used in the building construction industry. Indexes are provided for both Residential and Non-Residential building construction and each series is further sub-divided into four classes of activity - Structural, Architectural, Mechanical and Electrical. Weighting data for some 50 commodities are derived from values estimated from the 1979 Input-Output tables adjusted to 1981 price levels. Materials selected for inclusion and their associated values are those used in significant quantities in the construction and renovation of buildings only.

Error detection

Indexes are subject to revision every month up to 6 previous months retrospectively through the follow-ups of non-response samples. Materials selling prices are used as proxies for purchased prices.

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.
