2.1. Data description

The vineyard data set includes data on the structure of vineyards in the European Union. It covers the holdings growing vines intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation of before mentioned vines and the area covered by these vines.  The data concerns the vine types, degree of specialisation of vine-grower holdings, main varieties of grapes and age of plants. Some indicators are collected at national level, others a NUTS2 level.  The data are extracted from the vineyard register. The Member States, which have more than 500 ha of vines for other purpose than table grape production need to collect the data.

The reference year of the data described in this report is the year 2020.
2.2. Classification system

The classification system used in the vineyard data has several dimensions:  type of vineyards, degree of specialisation of the holding, main varieties (> 500 ha t national level), age of plants and size classes of holdings. More information can be found in the Handbook.
2.3. Coverage - sector

Growing of grapes for other purposes than table grapes (mainly for wine, juice, raisins) (part of NACE rev.  2 classification of A01.21: growing of grapes) and plant propagation for vines (part of NACE rev.  2 classification of A01.30: plant propagation).
2.4. Statistical concepts and definitions

Is there a national legislation covering structural vineyard statistics? YES
Name of the legislation

National Statistics Act (OJ HR No. 25/20)
If yes, provide a link


https://www.dzs.hr/Eng/about_us/Legals/Official_Statistics_Act_2020.pdf
Scope and coverage of the legislation

The Official Statistics Act, lays down in its Article 47 (OG, No. 25/20) the right of the CBS to use all administrative data sources for the purpose of conducting official statistics tasks.

Furthermore, Article 41(1) determines that CBS and other producers of official statistics shall have the right to access administrative data sources and data collected using the observation and monitoring method for the purpose of carrying out official statistics activities, free of charge

According to Article 41(2) the CBS may propose to the producers of administrative data sources appropriate development of methods and systems for managing administrative data sources, in order to reduce the burden on reporting units and for other needs of official statistics.

4. Quality management Top
4.1. Quality assurance

Is there a quality management process in place for vineyard statistics? YES
If yes, what are the components?

The Agency periodically carries out visual and administrative control data. The controls consist of: visual control LPIS to block DOF method, visual inspection of final LPIS data (final visual verification), control in the field of final LPIS data (GPS measurements, type of land use, georeferenced images integrated into the database), based on update new DOF every 3-5 years.
The data in the file on the production control wine inspectors, and in the case of established irregularities producers referred to in the Regional offices of the Agency to correct previously submitted statement, more severe forms of abuse data are punished misdemeanour charges. Data on production further checked with the surrender requirements of the manufacturers of putting wine produced on the market.
All controls (administrative controls and on-site), relating to the verification of files of the winegrower, are documented in the Central office of the Agency, and control related to files in production are documented in the Ministry of Agriculture by the wine-making inspectors.
Personal data is updated on the basis of data obtained from the relevant institutions (Ministry of Interior, the Crafts Register, Department of Viticulture and Enology). The data is updated periodically.

6.3.2. Measurement error

Statistics corrects possible errors of measurement using the logic-numeric control. We are trying to avoid the measurement error by control data and process validation.

After data entry, extreme values of variables are checked and corrected if necessary.
6.3.3. Non response error

In the context of vineyard data collection the non-response is understood as missing characteristics in the vineyard register
