The survey on domestic and outbound tourism and business trips is being realized by Statistical Office of the Slovak Republic since 2003. The purpose of this survey is to provide basic information about tourism demand on behalf of domestic users in terms of international rules. Survey was realized quarterly on the base of representative sample of cca 1200 respondents older than 15 years. In 2014, survey was connected to Labour Force Survey (LFS) and data has been collected within LFS survey during the last visit of households (5th visit) and since 2018 during the first visit of households. Since January 2021 the survey is collected separately from LFS, tourism is no more a part of LFS sample. The respondent, who travelled and stayed in the surveyed time period for personal or business purposes outside his/her usual environment, provides information. Other respondents specify their reasons for not travelling. Data from sample survey are grossed-up to the whole population of people older than 15 years.

Methodological notes for tourism statistics

The Quality policy is defined and publicly accessible in the Quality Declaration and Quality Policy documents. The Quality Declaration expresses the basic ideas and commitments of the President and top management of the SOSR for the Quality Policy as well as increasing efficiency and effectiveness of the integrated management system of the SOSR.

Quality Declaration

Quality policy is based on the mission of the Statistical Office of the Slovak Republic: to provide high quality and objective statistical products and services by keeping confidentiality of statistical data and by minimising burden on interested parties using effectively existing resources with the aim to support improvement of the information and intellectual capital of our customers. In this way we want to contribute to reduce risks and improve effectiveness in their decision making processes and so to support the sustainable development of the Slovak Republic as the part of EU.

Quality policy

The Quality manual describes the documented procedures of the quality system that are used for implementation and continuous improvement of the quality management system in SOSR. It contains a description of the quality management system and the fulfillment of requirements ISO 9001 standards. Application of the manual in practice ensures that all activities that have an impact on the quality of the products created are planned, managed, reviewed, evaluated and meet requirements.

Quality manual

The European Statistics Code of Practice is the basis of the common quality framework of the European Statistical System. It is a self-regulatory tool and it is based on 16 Principles covering the institutional environment, statistical processes and statistical outputs. A set of indicators of best practices and standards for each of the Principles provides guidelines and benchmarks for reviewing the implementation of the Code of Practice, thus increasing transparency within the European Statistical System.

In 2013-2018 a sample size of the survey was based on the sample system of Labour Force Survey. Since January 2021 the survey is collected separately from LFS, tourism is no longer a part of LFS sample, however, it is based on the same criteria and sample size. The LFS and current sample is based on a Population Census conducted once in ten years (last time in 2021). There is a lack of information on new statistical units during a rather long period. Errors in addresses of dwellings are also a problem; possible small under-coverage in case of collective households, persons living in convents, members of the Slovak embassies and institutions abroad, and students living in dormitories or boarding schools, for which the data is not collected. Unit non-response rate for trips with overnight stays represented 2,5% per year. The grossing-up methods are used for dealing with unit non-response. Item non-response-rate is lower than 0,5% in qualitative variables. Expenditure non-response rate is on average 7% in the year 2022 (the highest non-response rate is in expenditure related to accommodation and transport).

See 3.7 (in case of deviations for geographical coverage)

Comparison is made between domestic and outbound survey with two other statistics - Accommodation statistics and Statistics of tour operators and travel agencies (TA/TO). Within domestic survey, the number of trips and number of nights of domestic tourists is compared with number of visitors and nights in accommodation statistics. Results are more or less comparable on yearly basis. Outbound tourism trips are compared with survey conducted by TA/TO. Only some destinations are compared, where high percentage of trips are organized by TA/TO (for example Türkiye, Bulgaria). Data from accommodation statistics (average price of accommodation per night by category of accommodation and by region) are also used within imputation of expenditure on accommodation in domestic and outbound survey. In reference year 2022 there has been used voluntary data collection "Monthly accommodation data broken down by country / world geographical area of the guest" for mirroring. Data from yearly accommodation statistics from selected countries databases has been also used for comparison outbound tourism trips of Slovak residents.

SOSR regularly monitors the cost and burden of reporting units. The cost and burden measurement at the level of European Statistical Products is in competence of the Resources Directors Group within Eurostat.

The Revision policy regulates the general rules and procedures applied in revisions at the SOSR. The same revision policy applies to national and international users. In accordance with the Revision policy, the reason of the revision is always indicated.

The Revisions policy as well as the Revisions calendar is available to users on the web portal of the SOSR.

• Policy and calendar of revisions of the SOSR

SOSR distinguishes the following revisions:

From the content point of view:

- incorporation of better quality data based on a more complete source, including replacing imputations with collected data,

- correction of data as a result of updating seasonal factors and changing the base period,

- data modification based on more accurate methodology (in concepts, definitions and classifications) and changes in statistical methods,

- performing corrections in source data and calculations.

In terms of time, SOSR divides the revisions into:

- ordinary revisions are revisions without significant modifications of the methodologies. These are usually more significant data corrections, including large values ​​obtained from new sources. They are carried out periodically on precisely set up dates, to update monthly and quarterly data, until the next publication of the data.

- annual revisions are revisions that are made when all monthly and quarterly data are available and more detailed results from annual surveys are already available.

- extraordinary and major revisions are revisions of definitive data due to significant methodological changes resulting from revision of methodologies, changes in procedures and statistical-mathematical calculation methods or data corrections. An extraordinary revision may result (e.g. by changing the definition) in break in time series data comparability.

Only final data are published. Data will be revised only when errors occur.
