Reference period: The time period for which the ICPI equals 100; currently this is the year 2001.

Collection period: The first quarter of the calendar year following the reference year.

Data sources and methodology

Target population

The universe for the ICPI consists of a sample of infrastructure construction projects completed by the client and funded by municipal development charges.

Instrument design

This methodology does not apply.

Sampling

The sample of infrastructure construction projects funded by development charges is supplied by the client.

Data sources

Data are collected from other Statistics Canada surveys and/or other sources.

Prices are collected for three general categories of inputs; materials and equipment, labour and expenditures funded by development charges. Price series related to materials and equipment come from the Statistics Canada Industrial Product Price Index (IPPI), Non-residential Building Construction Price Index (NRBCPI) and Machinery and Equipment Price Index (MEPI) series. Data on labour costs comes from the Statistics Canada Construction Union Wage Rate Index (CUWRI) series and the client. Information pertaining to expenditures funded by development charges is supplied by the client.

Error detection

Error detection is conducted during post collection editing, through a system of data validity specifications. Failing records are reviewed for editing and corrected when necessary.

Imputation

This methodology type does not apply to this statistical program.

Estimation

The weights are derived from information relating to completed infrastructure construction projects, as supplied to Statistics Canada by the client. From this information, representative pricing models are produced and the corresponding weights are used to aggregate the sub-component series into the total series.

Quality evaluation

The quality of this index is maintained through the expertise of the trained analysts assigned to it. They develop a thorough knowledge of the domain, which is supplemented by outside personal contacts. Prior to dissemination, the price indexes are analyzed and historic trends reviewed.

Disclosure control

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

Collected data are converted to an index and released as such so that it is not possible to identify the raw capital expenditures data supplied by the client.
