In order to do this, each country provides a quality report within the 9 months after the year-end. The link is as follows:

      https://ec.europa.eu/eurostat/cache/metadata/en/tour_occ_esms.htm

• 11. Quality management

  • 11.1. Quality assurance

    • Quality assurance framework for the INE statistics is based on the ESSCoP, the European Statistics Code of Practice made by EUROSTAT. The ESSCoP is made up of 16 principles, gathered in three areas: Institutional Environment, Processes and Products. Each principle is associated with some indicators which make possible to measure it. In order to evaluate quality, EUROSTAT provides different tools: the indicators mentioned above, Self-assessment based on the DESAP model, peer review, user satisfaction surveys and other proceedings for evaluation.

      The Tourist Campsite Occupancy Survey carries out on a regular basis review activities on the statistical process in order to comply with the quality conditions required both at national and international levels. The main activities are the review of collected data such as the survey directory, as well as microfiltering when receiving data and microfiltering afterwards. improvement in the data collection systems (IRIA).

  • 11.2. Quality assessment

    • As can be seen in the following sections, where the quality indicators are gathered in detail, the COS shows a very good quality, since the data for the operation is available in a 30 days period of time. The total lack of response usually is around 7% for provisional data and 3% for final data, and variation coefficients also have levels lower than 0.9 for the main variables. Updates of the directory are carried out periodically. Finally, the Eurostat Methodology regarding tourism surveys is also followed: Methodological Manual for Tourism Statistics, available in the following link: https://ec.europa.eu/eurostat/web/products-manuals-and-guidelines/-/ks-gq-14-013

• 12. Relevance

  • 12.1. User needs

    • Users are very varied: tourism board/consortium, individuals, establishments, consultancy companies, Autonomous Community governments, city councils, universities, associations of accommodations and catering entrepeneurs. The data they receive is used for analysis, studies, reports and designing of policies. The needs of users that are not satisfied are those that do not comply with the conditions of statistical secrecy and significance. Apart from the information available on the webpage, users also ask for data for periods different from those published and for customised areas.

  • 12.2. User satisfaction

    • The INE has carried out general user satisfaction surveys in 2007, 2010, 2013,  2016 and 2019 and it plans to continue doing so every three years. The purpose of these surveys is to find out what users think about the quality of the information of the INE statistics and the extent to which their needs of information are covered. In addition, additional surveys are carried out in order to acknowledge better other fields such as dissemination of the information, quality of some publications...

      On the INE website, in its section Methods and Projects / Quality and Code of Practice / INE quality management / User surveys are available surveys conducted to date.(Click  next link)

       

  • 12.3. Completeness

    • The COS is consistent with all the requirements established by the international standards related to the tourism statistics from a supply perspective. 100% of the information requested by the regulation is supplied. (R1=100%)

• 13. Accuracy and reliability

  • 13.1. Overall accuracy

    • Estimators used are non-biased, therefore the bias is zero. Regarding non-sampling errors, it is intended to minimise both coverage and total non-response errors. For more information, the methodology for this survey can be consulted through the following link: https://www.ine.es/dyngs/INEbase/en/operacion.htm?c=Estadistica_C&cid=1254736176961&menu=metodologia&idp=1254735576863

  • 13.2. Sampling error

    • In order to measure the precision of this statistical operation, there are coefficients of variation for the variables travellers and overnight stays, differentiating between residents in Spain and residents abroad. The values of the coefficients of variation can be consulted through the following link:

      https://www.ine.es/jaxiT3/Tabla.htm?t=7905&L=1

      For example, travellers in October 2024 A1=1.12%

  • 13.3. Non-sampling error

    • The estimators used are non-biased, therefore the bias is zero. Among non-sampling errors, coverage errors are minimised by periodically carrying out crosses between the directories of the Autonomous Communities and the directory of the COS, in order to find potential duplicates, establishments that are missing or out of business. Total non-response errors are minimised between provisional and final data, thanks to re-contacting the units that did not respond. Moreover, an imputation of data is carried out for these cases. Among non-sampling errors, there is information available on the lack of response, the non-response rate being A4 =2.9 in 2021, definitive data.

• 14. Timeliness and punctuality

  • 14.1. Timeliness

    • The number of days from the reference day of data until the publication of provisional data is 30 days (TP1=30 days), while for final data the period is one year and one month for the months of January to June (TP2=13 months), and for the rest of the months final data is published during the 3rd quarter. In other words, provisional data for March 2024 and final data for March 2023 are published in April 2024, and final data for 2023 not published before ar published in September 2024.

  • 14.2. Punctuality

    • Each publication has been disseminated in accordance with the publication calendar. The calendar can be viewed at the following link: https://www.ine.es/en/daco/daco41/calen_en.htm

      TP3=100%

• 15. Coherence and Comparability

  • 15.1. Comparability - geographical

    • The availability of a methodology, and the design and common process of collection, scrubbing, edition and elevation throughout the whole geographical scope ensures the comparability of data between the different Autonomous Communities, provinces, tourist areas and tourist spots. On the other hand, adapting the methodology to the reglulation 692/2011 enables for the comparability with the remaining EU countries.

  • 15.2. Comparability - over time

    • Movement of Travellers in Campsites Survey was created in the 70s. In 1999 it was replaced with the Campsite Occupancy Survey and the temporary series is comparable ever since. The series has 310 elements in December 2024 (CC2=310).

  • 15.3. Coherence - cross domain

    • Though the variables gathered in this survey are not collected in any other survey, a coherence is observed between the values obtained and the evolution of the economy.

  • 15.4. Coherence - internal

    • The data has complete internal coherence, as it is based on the same set of microdata, and is calculated using the same estimation methods for the different breakdowns. The arithmetic and accounting identities are observed in the production of the data sets.

• 16. Cost and burden

  • 16.1. Cost and burden

    • The estimation of the budgetary credit necessary to finance this operation , as foreseen in the 2025 Annual Program, comes to a total of 11,514.54 thousand Euros in the INE budget.

      This estimation concerns tor the Occupancy Survey in Tourist Accommodations (cod. 9621 in PEN) that is formed by five statistical operation, being Camping Occupancy Survey one of them

      The information on the burden on informants is not provided.

• 17. Data revision

  • 17.1. Data revision - policy

    • The INE of Spain has a policy which regulates the basic aspects of statistical data revision, seeking to ensure process transparency and product quality. This policy is laid out in the document approved by the INE board of directors on 13 March of 2015, which is available on the INE website, in the section "Methods and projects/Quality and Code of Practice/INE’s Quality management/INE’s Revision policy" (link).

      This general policy sets the criteria that the different type of revisions should follow:  routine revision- it is the case of statistics whose production process includes regular revisions-; more extensive revision- when methodological or basic reference source changes take place-; and exceptional revision- for instance, when an error appears in a published statistic-.

      The revision policy is as follows: once the results are published in t+30, more questionnaires from the reference month are received, and therefore, the final version of the results presents greater coverage (increasing from a response rate of 93% in the provisional results to a rate of 98% in the final results). Each year, a more detailed release than the monthly one is released in June, with data from the previous year. This release is final. Although, from January to May, the same day when provisional results for the reference month are released, the final results for the previous month are also released.

  • 17.2. Data revision - practice

    • Each month, the provisional data for the previous month is published, as well as the final data for the previous month of the previous year until June when all final data are published that were not previously disseminated. The quality indicators used are MAR, absolute average revision, and RMAR, relative average revision, obtained from the main variables, travellers, and overnight stays.

      The annual average values in 2017-2018-2019-2020-2021 are:

      A6 MAR travellers = 5,349.99

      A6 MAR overnight stays = 33,693.19

      A6 RMAR travellers = 0.53275%

      A6 RMAR overnight stays = 0.69370%

  • 18.1. Source data

    • The INE compiles a national directory of holiday dwellings, using the records sent by the Tourism Boards of the Autonomous Communities. This directory contains the following information for each dwelling: denomination, direction, category, aperture length, number of pitches, caravans, and bungalows. A stratified sampling is used, by province and category.

  • 18.2. Frequency of data collection

    • Monthly

  • 18.3. Data collection

    • Collecting methods include: CAWI, postal service, fax, mail, automatic data collection via XML. Information in questionnaires is collected and filtered in a decentralised manner. There are two types of questionnaires: the weekly one, that collects information on seven consecutive reference days, and the monthly one, that collects information on data from the entire month. The questionnaire is updated on a yearly basis with the new EU countries.

  • 18.4. Data validation

    • The procedure for supervising the data validation consists of applying a series of validations to the questionnaires. In the event that any inconsistency is detected, the INE contacts the establishment again. When all of the data has been collected, it is revised again in a centralised fashion. Lastly, a macrofiltering is performed.

  • 18.5. Data compilation

    • Firstly, there is a decentralised microfiltering process to detect and filter errors and inconsistencies in the questionnaires. Subsequently, the esmitaros are obtained at a central level. Subsequently, a macrofiltering is performed, prior to the tabulation and dissemination of the results.

  • 18.6. Adjustment

    • No adjustments apply.
