Capacity:

The surveys on the capacity of hotels, similar establishments and tourist campsites (NACE Rev. 2. 55.1, 55.3) and of the holiday and other short-stay accommodation establishments (NACE Rev.2, 55.2)  are monthly census surveys conducted pursuant to Regulation (EU) No 692/2011 of the European Parliament and of the Council.

They are addressed to hotels, similar establishments and tourist campsites which are registered in the Hellenic Chamber of Hotels. Capacity statistics regarding the holiday and other short-stay accommodation establishments (NACE Rev.2, 55.2) are compiled  on the basis of ELSTAT’s Statistical Register of short-stay accommodation establishments, that is regularly updated by the according register of the Ministry of Tourism.

The compiled tables for NACE Rev.2 551 contain annual data on the number of establishments, of bedrooms and of bedplaces.

Occupancy:

Monthly statistical data on arrivals and nights spent in hotels, similar establishments and tourist campsites (NACE Rev. 2. 55.1, 55.3) are collected by means of a census survey, which is carried out by ELSTAT pursuant to Regulation (EU) No 692/2011 of the European Parliament and of the Council. The afore-mentioned survey is addressed to the hotels in Greece which are registered in the Hellenic Chamber of Hotels.

The occupancy statistics regarding the holiday and short-stay accommodation establishments (NACE Rev.2, 55.2) are compiled by means of a census survey to the relevant establishments registered in ELSTAT’s Statistical Register of short-stay accommodation establishments, that is regularly updated by the according register of the Ministry of Tourism.

The main variables collected are arrivals and nights spent by country of origin and number of occupied rooms.

Moreover, the occupancy rate of bed places and the occupancy rate of bedrooms for NACE Rev.2 55.1 establishments are calculated.

For the compilation of  final data of arrivals and nights spent in hotels, similar establishments, tourist campsites and short stay accomodation establishments, both data collected by the survey and administrative data sources are used. Specifically:

NACE 55.1, 55.3

a. the establishments of the Register of hotels and tourist campsites, are identified on the basis of administrative data for each reference period.

b. the survey is conducted on the afore-mentioned establishments

c. for the percentage of accommodation establishments that are in operation but do not respond to the survey, statistical methods were used for addressing non-response by grossing-up the collected data to the 100% of the total of the available bed-places.

NACE 55.2

a. the establishments in operation for each reference month, are identified on the basis of administrative data

b. the survey is conducted on the short-stay accommodation establishments

c. for the percentage of the accommodation establishments that were in operation but despite the reminders, did not respond to the survey, statistical methods are used for addressing non-response by grossing-up the collected data to the 100% of the total of the establishments. For this purpose, the target population is stratified by the following stratification criteria: Prefecture that the establishment is located, Degree of Urbanization (densely, intermediate and thinly populated areas), coastal or non-coastal areas, class of the establishment (1 key, 2 keys, 3 or 4 keys and rest of establishments) and size of the establishments based on the number of rooms (0-5 rooms, 6-9 rooms, 10-16 rooms, 17 rooms and over).

Accommodation establishments are classified according to NACE Rev.2 classification (groups 55.1, 55.2 and 55.3).

Regional breakdowns of capacity and occupancy statistics are based on the Nomenclature of Territorial Units for Statistics.

For the country of origin of the guests, country codes based on the ISO 3166 (International Organization of Standardization – alpha-2 format) are used.

NACE Rev.2 - 55.1, 55.2 and 55.3

• ELSTAT protects and does not disseminate data it has obtained or it has access to, which enable the direct or indirect identification of the statistical units that have provided them by the disclosure of individual information directly received for statistical purposes or indirectly supplied from administrative or other sources. ELSTAT takes all appropriate preventive measures so as to render impossible the identification of individual statistical units by technical or other means that might reasonably be used by a third party. Statistical data that could potentially enable the identification of the statistical unit are disseminated by ELSTAT if and only if

12.3.1 Completeness

12.3.2 Thresholds used ("limitation of the scope")

Coverage errors may occur either because of coverage issues in the administrative data sources used for the identification of the population frame of the surveys, or because the actual month of operation is not known for those (seasonal) establishments that do not respond to the surveys.

Item non-response is very limited.

The afore-mentioned issues are addressed to a great extent by the surveys or during the data compilation phase and, therefore, the overall accuracy of the capacity and occupancy statistics is very high.

13.2.1 Sampling errors - indicators (Occupancy only)

13.2.2 Additional comments on sampling error

13.3.1 Coverage-errors

13.3.2 Unit non-response (for the reference month mentioned under 5.2)

13.3.3 Methods used for dealing with/minimising unit-non response

13.3.4 Item non-response

13.3.5 Additional comments on non-sampling error (e.g. in case the reference month is very different from other months in terms of non-response)

See 3.7

The survey results are not compared to other sources or statistical domains.

Coherence between annual and monthly data: The data are characterized by internal coherence; same  definitions, database and methodology are used.

Cost and burden are not systematically collected.

18.3.1 Type of survey

18.3.2 Data collection methods

For the compilation of 2022 final data additional administrative sources were used in combination with statistical methods for addressing non-response by grossing-up the collected data to the 100% of the total of the available bed-places. 

The majority of tourist accommodation establishments in Greece operate on a seasonal basis. In order to address non-response for each reference year T, a final reminder is sent out to the establishments that have not responded to the survey, during the spring of the next year (T+1), when establishments that operate on a seasonal basis re-open.

For hotels, similar establishments and tourist campsites (NACE Rev. 2, 55.1 & 55.3) data  is compiled through the collection and processing of the relevant data submitted for each month of operation. Regular reminders are sent out to the establishments that do not responded to the survey, for submitting the data. For the percentage of establishments, which despite the reminders do not respond to the survey, supplementary administrative data are used and statistical methods are applied for grossing-up of the results to the total of establishments. The missing monthly data for a certain establishment is imputed based on the corresponding data of the previous year, when available, and the annual trend recorded in similar establishments. 

For short stay accommodation establishments (NACE Rev. 2, 55.2) a single stratified sampling method is applied. The stratification criteria of the short-stay accommodation establishments are: the Prefecture where the establishment is located, the class category of the establishment, the Degree of Urbanization (densely, intermediate and thinly populated area) of the Local Administrative Unit where the establishment is located and the size class of the establishment (based on the number of bedrooms).
