This survey collects the financial and operating data needed to produce statistics on the Database and Directory Publishing industry in Canada.
Data release - This survey does not release any data, for confidentiality reasons.
Description
This survey collects the financial and operating data needed to produce statistics on the Database and Directory Publishing industry in Canada. These data are aggregated with information from other sources to produce official estimates of national and provincial economic production in Canada. The estimates are used by government for national and regional programs and policy planning. Results of this survey are not made available to the public, due to industry concentration and Statistics Canada's provisions to protect the confidentiality of individual respondents.
Statistical activity
The survey is administered as part of the Unified Enterprise Survey program (UES). The UES program has been designed to integrate, gradually over time, the approximately 200 separate business surveys into a single master survey program. The UES aims at collecting more industry and product detail at the provincial level than was previously possible while avoiding overlap between different survey questionnaires. The redesigned business survey questionnaires have a consistent look, structure and content. The unified approach makes reporting easier for firms operating in different industries because they can provide similar information for each branch operation. This way they avoid having to respond to questionnaires that differ for each industry in terms of format, wording and even concepts.
This survey is part of the Service Industries Program. The survey data gathered are used to compile aggregate statistics for over thirty service industry groupings. Financial data, including revenue, expense and profit statistics are available for all of the surveys in the program. In addition, many compile and disseminate industry-specific information.

Data sources and methodology
Target population
The target population consists of all statistical establishments (sometimes referred to as firms or units) classified as Database and Directory Publishers according to the North American Industry Classification System (NAICS) during the reference year.
Instrument design
The survey questionnaires comprise financial characteristics such as sources of revenue, details of expenses and employment characteristics. Based on contacts with respondents and data users, some modifications have been incorporated to the questionnaires in order to reflect the nature of the industry surveyed. The changes were field tested to ensure that they were reasonable and sustainable.
Sampling
This survey is a census with a cross-sectional design.
This methodology does not apply.
Data sources
Data collection for this reference period: June 2001 to September 2001
Responding to this survey is mandatory.
Data are collected directly from survey respondents and extracted from administrative files.
The basic objective of the survey is to produce estimates for the whole industry, incorporated and unincorporated businesses. The data come from two different sources: a census of all businesses with revenue above or equal to a certain threshold (Note: the threshold varies between surveys and sometimes between provinces in the same survey) and administrative data for businesses with revenue below the specified threshold. It should be noted that only financial information is obtained from administrative sources, e.g., revenue, expenses, depreciation and salaries, wages and benefits. Characteristics such as revenue by type of service are collected only for surveyed establishments.
Data are collected through a mail-out/mail-back process, while providing respondents with the option of telephone or electronic filing methods.
Follow-up procedures are applied when a questionnaire has not been received after a pre-specified period of time.

Error detection
Error detection is an integral part of both collection and data processing activities. Automated edits are applied to data records during collection to identify reporting and capture errors. These edits identify potential errors based on year-over-year changes in key variables, totals, and ratios that exceed tolerance thresholds, as well as identify problems in the consistency of collected data (e.g. a total variable does not equal the sum of its parts). During data processing, other edits are used to automatically detect errors or inconsistencies that remain in the data following collection. These edits include value edits (e.g. Value > 0, Value > -500, Value = 0), linear equality edits (e.g. Value1 + Value2 = Total Value), linear inequality edits (e.g. Value1 >= Value2), and equivalency edits (e.g. Value1 = Value2). When errors are found, they can be corrected using the failed edit follow up process during collection or via imputation. Extreme values are also flagged as outliers, using automated methods based on the distribution of the collected information. Following their detection, these values are reviewed in order to assess their reliability. Manual review of other units may lead to additional outliers identified. These outliers are excluded from use in the calculation of ratios and trends used for imputation, and during donor imputation. In general, every effort is made to minimize the non-sampling errors of omission, duplication, misclassification, reporting and processing.
Imputation
When non-response occurs, when respondents do not completely answer the questionnaire, or when reported data are considered incorrect during the error detection steps, imputation is used to fill in the missing information and modify the incorrect information. Many methods of imputation may be used to complete a questionnaire, including manual changes made by an analyst. The automated, statistical techniques used to impute the missing data include deterministic imputation, replacement using historical data (with a trend calculated, when appropriate), replacement using auxiliary information available from other sources, replacement based on known data relationships for the sample unit, and replacement using data from a similar unit in the sample (known as donor imputation). Usually, key variables are imputed first and are used as anchors in subsequent steps to impute other, related variables.
Imputation generates a complete and coherent microdata file that covers all survey variables.
Estimation
This methodology type does not apply to this statistical program.
Quality evaluation
Prior to the data release, 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 and coherence with results from related economic indicators, historical trends, and information from other external sources (e.g. associations, trade publications or newspaper articles).
Disclosure control
Statistics Canada is prohibited by law from releasing any data which would divulge information obtained under the Statistics Act that relates to any identifiable person, business or organization without the prior knowledge or the consent in writing of that person, business or organization. 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.
Due to industry concentration and Statistics Canada's provisions to protect the confidentiality of individual respondents, results from this survey are not made available to the public.
Revisions and seasonal adjustment
This methodology does not apply to this survey.
Data accuracy
The portion of total industry revenue represented by completed questionnaires was 96% in 2000.
The surveyed Database and Directory Publishers represented 99% of the estimated industry revenues. The remainder of the estimate was derived from administrative data sources.
