Detailed information for August 2014

Data release - October 31, 2014

Description

The Monthly Survey of Food Services and Drinking Places provides estimates of the value of sales of restaurants, caterers, and drinking places by province and territory and by industry at the North American Industry Classification System (NAICS) four or six digit level. These data are used by federal and provincial governments, private associations and food service businesses for consulting, marketing and planning purposes. The provincial and federal governments use the information to estimate provincial taxation shares.

Reference period:
Month

Subjects

  • Accommodation and food
  • Business, consumer and property services

Data sources and methodology

Target population

The target population includes all statistical establishments that are classified as either food services or drinking places (NAICS 722) in the North American Industry Classification System (NAICS 2012).

Instrument design

This questionnaire collects data on monthly sales of food service establishments. The items on the questionnaire have remained unchanged for several years. Some minor modifications were made with the survey redesign of 2007 to facilitate its use and clarify a few elements. Associations representing the industry were consulted.

Sampling

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

The frame, derived from Statistics Canada's Business Register, includes about 82,500 enterprises with one or more establishment classified to NAICS 722. Each enterprise must be classified on the Business Register as alive and active. Most are simple enterprises (with a single establishment) but about 1,300 are complex enterprises (with multiple establishments) and they have about 7,600 establishments. The sampling unit is the enterprise which is a cluster of establishments classified to NAICS 722 belonging to the enterprise.

The sample is based on a stratified simple random design. The frame is stratified according to Province / Territory and by 4 or 6- digit NAICS: 722511 (Full service restaurants), 722512 (Limited service eating places), 7223 (Caterers and food service contractors), and 7224 (Drinking places). These strata are further stratified based on a revenue measure of enterprise size derived from the Business Register. The take-all stratum contains the complex enterprises and the large enterprises. There are two take-some strata that contain the medium size enterprises and in these strata a simple random sample is taken. The take-none strata contain the small enterprises where no sample is taken; instead administrative data (Goods and Services Tax- GST) is used for estimation. Overall, the sample size is about 2,000 enterprises covering more than 10,000 establishments.

An initial sample was drawn in 1998, when the survey was converted to NAICS. New samples were re-drawn in 2004, 2007 and 2008. The sample is refreshed each month by including a sample of births from the population. Every few years, all establishments in the sample are updated to take into account changes in their revenue, dead units are removed from the sample, and some small and medium-sized units are rotated out, while others are rotated into the sample. Starting with the reference month of March 2009, estimates are based on a restratified sample based on the list of enterprises and establishments on the Business Register as of December 2008. For additional information, consult the article "Monthly Survey of Food Services and Drinking Places: Impact of restratification" in the Documentation section below.

Data sources

Responding to this survey is mandatory.

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

Data collection, data capture, preliminary edit and follow-up are performed by regional office staff.

Data are collected through various methods, such as telephone, mail-out/mail-back and electronic questionnaire.

Follow-up procedures are applied when a questionnaire has not been received after a pre-specified period of time.

Administrative data (from the Goods and Services Tax - GST) are the main source for the estimates for the new take-none strata and for the take-some strata for the full-service restaurants and the limited-service eating places for the following provinces: Quebec, Ontario, Manitoba, Saskatchewan, Alberta and British Columbia.

Error detection

Data are examined for inconsistencies and errors using automated edits coupled with analytical review. Where possible, data will be verified using alternate sources.

Imputation

Imputation is used to estimate for non-response and missing data. Imputation methods include the use of historical monthly trends from data collected in previous years and from current GST data. Data from imputation sources that fail statistical edits are considered as outliers and are not used in the imputation process.

Estimation

Sales are estimated by multiplying each data response by its sampling weight. For the take-all strata the weight is 1 since all enterprises are selected in the sample. For the take-some strata, the sample is selected by simple random sampling and the weight is therefore the inverse of the probability of selection in the stratum.

In the population represented by the take-some strata of NAICS 722511 and 722512, in the provinces of British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, and Quebec (where the overall sample size is about 800 enterprises) Ratio Estimation is used. This method of estimation is a modification and extension to the use of the sampling weights. It improves the quality of the estimate by taking advantage of the high correlation between survey data and GST data. The use of administrative data also reduces response burden and survey costs. The approach of ratio estimation (for this part of the population) began with the January 2009 estimates.

There is no sample for the take-none strata. Instead, sales are estimated using the ratio estimation approach for all provinces and NAICS based on the data from the take-some strata.

The standard error and CV of the estimates are derived directly from the stratified simple random sample.

Quality evaluation

Prior to dissemination, combined survey results are analyzed for comparability. In general, this includes a detailed review of individual responses (especially for the largest companies), general economic conditions, historic trends, and comparisons with other data sources.

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

Monthly, preliminary estimates are provided for the reference month. Raw estimates, based on late responses, are revised for the two previous months. Seasonally adjusted estimates are computed using the X-12-ARIMA software and revised for the three previous months. At the end of each calendar year, seasonally adjusted estimates are revised to equal the sum of the raw estimates. Seasonal adjustment options are also reviewed on an annual basis and updated as required.

It is standard practice that every few years the sample is refreshed to ensure that the survey frame is up to date with births, deaths and other changes in the survey population. To that effect, a new sample was drawn in December 2008 and run in parallel with the old sample until May 2009. This new sample also reflected improvements made to the Business Register since the last sample refreshment (restratification) in March 2007. In addition the survey methodology has been refined to improve imputation of non-respondents, calendarization of reported data by respondents that do not report for a complete month, use of administrative (Goods and Services Tax) data, and modifications to seasonal adjustment options.

Historical revisions are made once a year for all months in the previous year(s). For more information concerning previous historical revisions, see the "Summary of changes over time" sidebar on this page.

Most recently, with the release of the March 2014 preliminary estimates, historical revisions have been made going back to January 2012. These revisions include replacing imputed data with reported data, introducing new births, and utilizing the most recent administrative data. The seasonally adjusted data series have been revised back to January 2009.

Data accuracy

The response rate, which is about 75%, is a measure of the proportion of those sample units that have responded in time for inclusion in the estimate.

The coefficient of variation is used to measure the sampling error of the estimates. The coefficient of variation, at the national level for total sales, is 0.8%.

However, this coefficient of variation does not include the component of sampling error derived from the model (as described in the section on estimation). This applies to the take-none strata and the take-some strata for NAICS 722511 and 722512, in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, and Quebec.
