See Regulation 692/2011, Delegated Regulation 2019/1681 and Methodological Manual for Tourism Statistics

Participation in tourism: the individual.
Tourism trips: the tourism trip with at least one overnight stay made by the individual.
Same-day visits: the same-day visit made by the individual.

The reporting units report on the tourism trips made during the reference period and give the details for different characteristics of the trip.

Participation in tourism: All residents aged 15 or over.

Tourism trips: All tourism trips of at least one overnight stay made outside the usual environment by the residents aged 15 or over.

Same-day visits: All outbound same-day visits made outside the usual environment by the residents aged 15 or over.

Comparable time series for participation in tourism trips as well as for tourism trips are available from 2000 - 2020. Changes were made in the methodology in 2021, and the statistic is therefore not comparable over time.

Regulation 692/2011

Regulation 1051/2011

Delegated Regulation 2019/1681

State Statistics Act (ZDSta)/Act on State Statistics (Official Gazette of the Republic of Slovenia, No. 45/95 and 9/01 )

All the requirements of the Regulation 692/2011 are taken into consideration. Statistical confidentiality is respected. Data are published relatively rapidly, data and metadata are easily accessible to users etc. 

The main problems regarding quality are relatively high coefficient of variation on detailed data (crossing several variables e.g. trips by country and type of transport) and decrease of response rate (general problem in all household surveys using CATI methodology).

Mixed mode, CATI and CAWI combination. Improved sampling process, improved questionnaire. 

See: Regulation 692/2011

All the requirements of Regulation on tourism statistics are taken into consideration. Because of national needs (especially needs for Balance of Payments, TSA) we started to collect data on same-day visits before the first reference year defined in the Regulation. At Statistical Office of the Republic of Slovenia for all individual fields of national statistics (for tourism as well) statistical advisory committees are formed. Members of these committees (external and internal experts) co-operate with SURS to provide quality, timely and relevant statistics. They can also introduce and suggest what kind of data would be desired to collect. In general there are no specific requirements for additional data, on the other hand there are some cases of requests for more detailed data (for example number of trips to a certain country that is less visited by Slovene residents). This data cannot be provided due to accuracy issues. Some other users include Slovenian tourist board, Bank of Slovenia, Institute of macroeconomic analysis and development, Universities and Ministry of the Economy, Tourism and Sport.    

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

Methods used for minimising unit non-response           

Respondents:                                                                

- A letter and brochure are sent to the address of selected person to inform the household that an interviewer will call and to inform them about the content of the survey.                                                                          

- Multiple phone calls at different periods of time.                                                          

- If the number of cell phone is available then the selected person is primary called at that phone number (we avoid the situation that someone else from the household instead of selected person refuses to put the selected person on the phone).                                  

- In certain cases proxy answers are allowed.                                         

- Simple and easily understood questions.  

Interviewers:                                                                                         

 - New interviewers undergo trainings and they get support materials.

 - Instructions for interviewers where they get few tips how to persuade the person to participate in the survey.

Methods used for dealing with unit non-response        

Grossing up methods are used for unit non-response and to adjust control variables to known population variables. For adjustment we used the following variables: sex, age, level of education, household size, type of settlement (depends on size and rural or not rural), statistical region.

Item non-response is allowed only for items regarding expenditures and some socio-demographic characteristics.

We used logical imputations and hot-deck imputation techniques. To lower non-response for expenditure items the selected person is informed via letter that they receive before starting the survey about which groups of expenditures on tourism trips they will be asked. 

Non-response error

- unit non-response: The non-response rate was 71.3%. The refusal rate was 28% of all eligible units. Other non-response was because we could not contact selected person, selected person was not able to participate etc. For dealing with unit non-response grossing up methods are used.

Description, examples of other types of non-response: Other types of non-response include persons that were not able to answer the questionnaire (i.e. illness, disability etc.) and unknown reasons for nonresponse.

- item non-response: significant item non-response appears for variables that refer to expenditures. For dealing with item non-response imputation methods are used.    

Imputation rate              

The imputation rate for items that refer to expenditures in 2022 were as follows:

- expenditures on transport: 2.25%
- expenditures on accommodation: 3.01%
- expenditures on food and drinks in restaurants and cafes: 0.22%
- other expenditures: 0.38%
 

Measurement error

- by interviewers: not understanding or misinterpreting the respondents answers, typing errors;

- by respondents: not understanding the questions, not knowing the answers, not interested in the survey.

Household survey

Tourism travels of domestic population

Update of the population frame: Continuously

Central Population Register - the source ("owner") of the register is Ministry of the Interior.

Units which represent over‑coverage are those units which are not eligible for the survey and were included in the sample due to the lack of information (e.g. still registered as permanent residents in Slovenia, but living abroad, etc.). Units which represent under-coverage are those units which should be included in the sample but were not: in the sample are not included residents who do not have phone number publicly available or we were not able to link the selected person with the suitable phone number.

The sample of persons selected from the Central Population Register is stratified systematic. The basis for the sampling frame are persons selected from the Central Population Register. Strata are defined by age group (4 groups), by level of attained education (4 groups) and by assigned public telephone number. Each stratum is sampled independently. The number of persons in each stratum is in principle proportional to the percentage of targeted population from strata. Their number slightly changes depending on the interviewing rates in the stratum in the past quarters. The survey is conducted by telephone (the name and the address of the selected sample of persons is linked with the phone directory) and by an online questionnaire. Certain coverage errors that affect the representativeness of strata are corrected in the final phase when calibration of weights is done.

Data on tourism travels of domestic population are collected by a computer assisted telephone survey (CATI) and by an online questionnaire (CAWI). The survey is carried out at the Call Centre of Statistical Office every three months: January, April, July and October, and lasts approximately four weeks. Before the start of the survey, we send a notification letter to the selected persons by post. In the letter for the telephone survey, we inform them that they will be called shortly by the interviewer of the statistical office and we will inform them about the content of the survey. In a survey letter via an online questionnaire, we send them a link to the online questionnaire and ask them to complete it by a certain deadline. In case they do not fill in the questionnaire in 7 or 14 days, we send them two more reminders. Before starting the survey, the survey methodologist carries out lessons for CATI interviewers (longer for new and shorter for experienced ones). Lessons cover theoretical part, where the interviewers get familiar with the methodology, communication skills and technical details. Practical part is then carried out on the computer, where on the basis of made up cases they interview each other (role play). Experienced interviewers attend shorter lessons where they get familiar with methodological novelties and with frequent mistakes and errors they made during their previous interviewing.

Not available

In order to lower the non-response rate, since the 3^rd quarter of 2006 we allow that for the chosen person another person in the household responds (proxy) about the travels and socio-demographic characteristics of the chosen person. Proxy interviews are allowed when the chosen person is at the time of interviewing absent from the household, is not able to participate or does not want to respond but allows that someone else answers instead. It is not necessary that the person who responds in the name of the selected person also participated in the trips, but this person must know all the answers. The share of proxy answers in 2022 was 10%.

Logical controls in the phase of interviewing:

- During the interview the program Blaise automatically points to incorrect values, to the so-called soft (warning) and hard (error) controls. Soft controls (warnings) alert the interviewer to check out the entered data and if it is correct, he confirms it and continues with the interview, if it is incorrect, he corrects it and then continues. Hard controls (errors) alert the interviewer that he entered wrong data. Hard controls do not allow a continuation until the correct answer is chosen.                                                     

- Listening to the conversation between the interviewers and respondents and at the same time monitoring the fulfilment of the questionnaire in Blaise.

- Same automatic controls in the program are in the CAWI questionnaire. 

Controls after the interviewing made by methodologist:                                           

- On the basis of requirements prepared by methodologist, lists are made containing the serial numbers of the questionnaires for the specific fields in which these requirements occur. The methodologist checks all these fields and, if necessary changes and corrects them according to the answers to other questions.

- Before saving data in the database, data are once again logically checked also taking into consideration Eurostat's validation rules.

Editing concerning non-response of units and non-response of items is made. Grossing up methods are used for unit non-response and to adjust control variables to known population variables (for adjustment, the following variables were used: sex, age, level of education, household size, type of settlement, statistical region). Missing and in some cases also inconsistent data for affected items are estimated by using the set of the imputation methods. Item non-response is allowed only for items regarding expenditures and some socio-demographic characteristics. We used logical imputations and hot-deck imputation techniques.
