Data sources and methodology

Target population

The universe consists of all cold storage warehouses storing dairy products.

Instrument design

The paper questionnaire has remained stable over the decades, although formats and wording have been modified to maintain its relevance based on feedback from respondents and users.

Sampling

This survey is a census.

Data are collected for all units of the target population; therefore, no sampling is done.

Data sources

Responding to this survey is mandatory.

Data are collected directly from survey respondents and extracted from administrative files.

Questionnaires are mailed to all public cold storage warehouses, and mailed back. Telephone follow-up procedures ensure a high rate of return during data collection.

Error detection

Both monthly reports and provincial totals are scrutinized to ensure that they are consistent with previous periods and industry trends.

Imputation

Missing reports are manually imputed based on previous reports, historical averages or ratios. This is required if the current month's data are not available and are usually updated with completed questionnaires the following month.

Quality evaluation

The survey results are evaluated through comparisons to previous estimates and other sources when available. Biological factors and industry limitations are used as a guide when evaluating the data or comparing to other data sets.

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.

Revisions and seasonal adjustment

For each quarterly release, the previous periods' data are revised if necessary. The revisions can be necessary when revisions are done to survey or administrative data.

Data accuracy

As this is a small census style survey with rigorous follow-up as required, data quality is deemed to be very high. In the case of a late report, telephone follow-up results in a high response rate. If the data cannot be obtained, estimates are made, and the data are revised the following month.

The data accuracy of this survey is high as the response rate is normally over 90% covering over 95% of the industry.
