The requirement to consult user needs is stated in Act No. 540/2001, Coll. of the Law on Official Statistics. Within the preparation of the Program of State Statistical Surveys, the user needs are consulted.

The Programme of State Statistical Surveys is a generally binding legal act compiled by the Statistical Office of the Slovak Republic in cooperation with ministries, other government authorities, and state organizations. It contains a list of statistical surveys that are organized and executed by the Statistical Office of the Slovak Republic, ministries, other government authorities, and state organizations. The Statistical Office of the Slovak Republic issues the Programme of State Statistical Surveys in the form of a decree published in the Collection of Legal Acts of the Slovak Republic.

The SO SR has established the Statistical Council as a permanent professional consultative body whose main task is to prepare and submit proposals and recommendations for the concepts of statistical surveys, to consult the Programme of State Statistical Surveys.

12.3  Completeness

Compliant with the requirements of Regulation on tourism statistics 692/2011, Commission Delegated Regulation (EU) 2019/1681, as well as recommendations laid down in the Methodological manual for tourism statistics.

13  Accuracy and reliabilityUp
13.1  Overall accuracy

Sample size of the survey is based on the sample system of the Labour Force Survey (the first visit in a household). The LFS sample is based on a Population Census conducted once in ten years (last time in 2011).

13.2  Sampling error

Over-coverage: Small over-coverage can be observed in terms of the sampled dwellings in case of their non-residential usage (recreational or commercial space), wrong addresses or temporarily empty flats (no persons with usual residence).

Under-coverage: Out of scope are household members of collective households, persons living in convents, members of the Slovak embassies and institutions abroad and students and schoolchildren living at dormitories or boarding schools, for which the data is not collected.

13.3  Non-sampling error
In 2019 unit non-response rate represented 1,1% per year. The grossing-up methods are used for dealing with unit non-response. Item non-response rate is lower than 1% in qualitative variables.
14  Timeliness and punctualityUp
14.1  Timeliness

No deviations have been recorded.

14.2  Punctuality

Release dates have been respected.

15  Coherence and comparabilityUp
15.1  Comparability - geographical

Indicators from the survey on domestic and outbound tourism are compiled for the entire territory of the Slovak Republic.

15.2  Comparability - over time

Comparable time series: 2003-2012. Break in time-series between years 2012 and 2013 is caused by methodological changes in the processing of data (collection of data is newly realized within Labour Force Survey, the sample size of tourism survey is based on LFS survey, data were collected within the last visit of LFS household and since 2018 during the first visit of LFS household).

15.3  Coherence - cross domain

The data are part of the comprehensive outputs of tourism statistics together with the relevant results from statistical surveys such as Monthly survey on the activity of accommodation facility (CR 1-12) and Annual survey on selected services in tourism (CR 6-01).

15.4  Coherence - internal

16  Cost and burdenUp

The number of households: 1200 households per month, estimated 18 040 individuals (respondents).
Actual sample size: 18 075.

  • The Revision Policy of the SO SR
  • Revision calendar

We distinguish:

  • Routine revisions – regular revisions of data not influenced by change of methodology. These are usually major data corrections, including changes due to the obtaining new data sources. The publication of the revised data is done periodically in line with Calendar of revisions
  • Annual revisions - when all monthly, quarterly data are available and more detailed results from annual surveys are already available.
  • Extra-ordinary and major revisions –revisions of definitive data due to changes of methodology, changes of classifications, change of base year, changes of mathematical/statistical methods of data calculation. Those revisions may result in a break in time series of data.
17.2  Data revision - practice

Only final data are published.

18  Statistical processingUp
18.1  Source data

The sampling design is a stratified two-stage probability sampling of dwelling units, using the Census of Population 2011 as the basis. The sampling frame was last updated in 2015. The strata are formed by (79) districts (correspond to the NUTS 4 level). The primary sampling units (PSU) correspond to the Census Administrative Units. These are selected at the first sampling stage in each district with probability proportional to the district’s population size. Each PSU can be selected more than once. At the second stage, dwelling units are selected from each instance of the PSU using a simple random sampling method. Within the domestic and outbound tourism survey (module attached to the LFS) individuals are interviewed during the 1st visit of the LFS household.

18.2  Frequency of data collection


18.3  Data collection

Within domestic and outbound tourism survey (module attached to the LFS) all individuals aged 15+ in households living in selected dwellings are interviewed during the 1st visit of the LFS household. 5 LFS visits in one dwelling are done for collecting data for LFS and during the first visit, interviewer collects also data for domestic and outbound tourism survey. Data for students living outside their usual environment (and households) in dormitories, schoolchildren at boarding schools and other types of dwellings are not collected.

18.4  Data validation

Data validation is performed according to the national validation rules and Eurostat validation rules and according to the national technical project of the survey. The data collection is followed by a validation process based on the logical control rules and the validation rules according to Regulation 692/2011. The aggregated data are compared with the previous year.

18.5  Data compilation

Data from domestic and outbound tourism are collected quarterly.

18.6  Adjustment

Unit non-response or missing data are imputed from relevant sources such as Accommodation statistics CR 1-12 (average price of an accommodation per night by category of accommodation and by region) which are used for imputation of tourism expenditure in domestic tourism.

Data from the Annual questionnaire on selected services in tourism CR 6-01 are also used within imputation of expenditure on outbound package trips. The results of the sample survey are calculated by mathematical-statistical methods for the entire population of people older than 15 years.
