Record number:

2189

The quarterly survey, Shipments of Solid Fuel Burning Heating Products measures the shipments of solid fuel burning heating products by Canadian manufacturers.

Data release - May 28, 2001

Description

This survey measures, on a quarterly basis, shipments of solid fuel burning heating products by Canadian manufacturers.

The quantities of solid fuel burning heating products shipped are used as an indicator of the economic condition of this industry and as an input to macro- and micro-economic studies to determine market shares and industry trends. Data are used by the business community, trade associations, federal and provincial departments and international organizations.

Reference period: Quarter

Collection period: The month following the reference period.

Subjects

  • Machinery, computers and electronics
  • Manufacturing

Data sources and methodology

Target population

The target population for this survey includes manufacturers in Canada of solid fuel burning heating products as defined in the Standard Classification of Goods (SCG), that report these products to the Annual Survey of Manufactures or ASML (record number 2103). This means that estimates from this quarterly survey do not cover the entire universe of solid fuel burning heating producers in Canada because the ASML does not survey all businesses. Instead, the ASML uses administrative data to cover the small and medium-sized establishments. These manufacturers are not part of this quarterly survey.

Instrument design

The questionnaire was developed in collaboration with Natural Resources Canada and Industry Canada. Regular dialogue is maintained with the users and the respondents and every effort is made to ensure that the questions asked are relevant and can be answered by the manufacturers.

Sampling

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

The target population includes all major manufacturers of Solid Fuel Burning Heating Products.

Statistical Units: Establishments
Sample Size: 29
Response Rate: Approximately 100% Population Size: 29

The survey Frame is based on the annual survey of manufactures (ASM). Since the ASM lags behind this commodity survey, there is a risk of under-coverage but this should be minimal because of advance information from the ASM frame and feedback from the monthly survey of manufacturing (MSM).

Data sources

Responding to this survey is mandatory.

Data are collected directly from survey respondents.

Data are collected each quarter from survey respondents using a mail-out / mail-back process. Data capture and preliminary editing are performed simultaneously to ensure validity of the data. Businesses from whom no response has been received or whose data may contain errors are followed-up by telephone or fax.

Under normal circumstance, data are collected, captured, edited, tabulated and published within 6-8 weeks after the reference period.

Error detection

In order to detect errors and internal inconsistencies, automated edits are applied to captured data to verify that totals equal the sum of components and that the data are consistent with previous month's data. Data that fail the edits are subject to manual inspection and possible corrective action.

In addition, subject matter experts analyse the data at a more aggregate level to detect and verify any large quarter-to-quarter or year-over-year changes for the industry.

Imputation

Missing data for the current period are imputed automatically by applying to the previous quarter's value, the quarter-to-quarter change observed for the same period in the previous year, for the unit in question. However, an option exists for analysts to manually override this imputation with a better estimate based on pertinent knowledge about the industry or the business.

Estimation

This methodology type does not apply to this statistical program.

Quality evaluation

Survey results are analyzed to ensure comparability with patterns observed in the historical data series and the economic condition of the industry. Information available from other sources such as the media, other government organizations and industry association are also used in the validation process.

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.

Confidentiality analysis includes the detection of possible direct disclosure, which occurs when the value in a tabulation cell is composed of a few respondents or when the cell is dominated by a few companies.

Revisions and seasonal adjustment

Data may be revised to include amended information or reports from respondents that are received after the end of the collection cycle. Revisions are disseminated in a subsequent period and reflected in the CANSIM series.

Data accuracy

All survey data, from whatever source, are subject to error. The main sources of error are Coverage Errors, Response Errors, Processing Errors, and Non-response Errors.

Coverage, response and processing errors do not easily lend themselves to quantification. Where they are detected, they are corrected. On a monthly basis, late or non-responses are imputed using a variety of methods, the most common being trend analysis.

In the case of the Solid Fuel Burning Heating Products, there is a possibility of under-coverage because the frame is derived from the ASM, which lags behind the current survey. However, the risk of under-coverage is minimal because of advance information from the ASM frame, feed-back from MSM and information from other sources.
