11.2. Quality management - assessment
11.2.1 Main strengths

Data collection, treatment and publication follows Eurostat Methodological Manual. This improves comparability with other countries.

Interviewers are the same over a long time period, this assures quality and comparability.

Monitoring and supervising of the interviewers allows to detect where there is space of improvement.

Data is checked regularly during data collection, to improve data collection where necessary.

Data treatment is clearly documented.

Metadata report is delivered to Eurostat.
11.2.2 Main weaknesses

Memory-effect due to the gap between the moment the interview is carried out and the information reference period.
11.2.3 Quality improvements compared with previous reference year

With a better follow-up of the interviewers, time lag between observation period and contact period has been reduced.


12. Relevance Top
12.1. Relevance - User Needs
12.1.1 European level

See: Regulation 692/2011
12.1.2 Main users on a national level

User needs were analysed by Eurostat. In addition user requests are collected and regularly compared to data delivered by the survey.
12.2. Relevance - User Satisfaction

[Optional]
12.3. Completeness
12.3.1 Completeness

Compliant with the requirements of Regulation on tourism statistics 692/2011 as well as recommendations laid down in the Methodological Manual for tourism statistics.
12.3.2 If not, please specify why and list deviations from Reg.


13. Accuracy Top
13.1. Accuracy - overall

Main possible error source is the memory effect (respondent might forget trips and expenditures).
This would lead to an underestimation of trips and expenses.

Sampling error vary among variables. Main variables are relatively accurate (e.g. Number of trips with purpose "leisure, recreation and holidays") whereas more detailed variables have larger sampling error (e.g. Number of trips by destination).

Concerning non-response, the main variables concerned are expenditure data.

13.3.4 Item non-response

13.3.4.1 Item non-response

Main item non response occurs for expenditure data.  These are for each expenditure category 20-25%. But in almost 90% of these cases an estimate of the total expenditure was specified.
13.3.4.2 Methods used for dealing with/minimising item non-response

Imputation based on characteristics of known variables (E.g. expenditure depending on length of trip and trip destination, purpose).

For national releases no imputation of values is done on the micro data.


13.3.5 Additional comments on non-sampling error (in case of second survey please briefly describe 13.3.1-13.3.4 here)

Main unit non-response occurs during the household budget survey (~35%) where the tourism interview is embedded. 

Additional comments on unit non-response: Here are only presented the numbers for the additional module on tourism behaviour. However, the main part of the refusals occurs during the Household Budget Survey. Respondent rate of tourism interview is about 90%.

Main item non-response occurs for expenditure data (~10%). These data are imputed for transmission to eurostat. Imputation rates of the other variables are less than 1%. For national publication, no imputation are made.

Imputation rate: 9.5% of the expenditure data is not complete (Not all expenditure types are known and the total is missing as well). These cases are imputed. If the total is available, then the missing expenditure of each category is imputed based on the total. (For national expenditure data, only the total is published)
Other imputed variables are destination type (<1%), accommodation (<1%) and type of reservation (<1%)

15.2.1 Participation in tourism

See 3.8.1

Comparable time series for national data are 1998, 2003, 2008 to 2018.

In 1998, 2008, 2009, 2010 and 2011, population aged 15+ was surveyed. In 2003 and since 2012, children between 6 and 14 were also included.
15.2.2 Tourism trips

See 3.8.2

Comparable time series for national data are 1998, 2003, 2008 to 2018.

In 1998, 2008, 2009, 2010 and 2011, population aged 15+ was surveyed. In 2003 and since 2012, children between 6 and 14 were also included.
15.2.3 Same-day visits (outbound)

See 3.8.3

Comparable time series for national data are 1998, 2003, 2008 to 2018.

In 1998, 2008, 2009, 2010 and 2011, population aged 15+ was surveyed. In 2003 and since 2012, children between 6 and 14 were also included.
15.3. Coherence - cross domain

A comparison with accommodation statistics showed that the number of domestic nights spent in rented accommodations was approximately 50% lower in the demand side survey. These differences may be due to different definitions.

As different methods apply, comparison with other data sources should only be done with caution and is not recommended.
