2.1. Data description
1. Brief history of the national survey 
In 2003 the Ministry of Agriculture and Forestry carried out the first census of agricultural holdings of Bulgaria in accordance with the EU legislation.

In 2005 and 2007 farm structure sample surveys based on list of holdings from Agricultural Census 2003 were conducted. Stratified sample of 40 000 holdings was designed. Methodology and definitions of the characteristics used were similar to those of the census, thus ensuring comparability with the results of the other EU Member States.

In the second half of 2010 the Ministry of Agriculture, Food and Forestry (MAFF) carried out the farm structure survey (FSS) and the survey on agricultural production methods (SAPM) on the entire country’s territory in accordance with the Law on Agricultural Census 2010 in Bulgaria. This was the first census carried out in Bulgaria being a member of the European Union (EU) and the second one, in compliance with the legislation of the EU. The census was conducted using a methodology consistent with the requirements of Regulation (EC) No 1166/2008 of the European Parliament and of the Council of 19 November 2008 on farm structure surveys and the survey on agricultural production methods and repealing Council Regulation (EEC) No 571/88 and Regulation (EC) No 1200/2009 of 30 November 2009 implementing Regulation (EC) No 1166/2008 of the European Parliament and of the Council on farm structure surveys and the survey on agricultural production methods, as regards to livestock unit coefficients and definitions of the characteristics. This ensured comparability of the results on the structure of agricultural holdings in Bulgaria and agricultural production methods with those of the EU Member States (MS).

The FSS surveys are the main source of information on the status and trends in agriculture. It has to provide a current economic, social and environmental overview of the agrarian sector needed for the decision making in the Common Agricultural Policy (CAP). The census data was taken as a basis for sampling of the FSS sample surveys and of the annual production surveys, to define the field of observation of the Farm Accountancy Data Network (FADN) and to start the creation a statistical farm register.


2. Legal framework of the national survey 
- the national legal framework The FSS 2016 was conducted in accordance with Regulation (EC) No 1166/2008 of the European Parliament and of the Council of 19 November 2008 on farm structure surveys and the survey on agricultural production methods and repealing Council Regulation (EEC) No 571/88, and Commission Regulation (EC) No 1200/2009 of 30 November 2009 and Regulation (EC) No 715/2014, implementing Regulation (EC) No 1166/2008 of the European Parliament and of the Council on farm structure surveys and the survey on agricultural production methods, as regards to livestock unit coefficients and definitions of the characteristics. The country applied lower national thresholds set out in the Law on Agricultural Census in 2010. 
- the obligations of the respondents with respect to the survey Respondents are obliged to provide information to statistical surveys included in the National Statistical Programme (Law on Statistics).  
- the identification, protection and obligations of survey enumerators Interviewers are identified with service cards and are obliged to interview the agricultural holdings and fill in the paper questionnaire. The interviewers' obligations are set in the service contract they sign with the MAFF.

2.5. Statistical unit
The national definition of the agricultural holding
According to Law on Agricultural Census 2010 Agricultural holding or “holding” is a separate technical and economic unit which has a single management and which produces agricultural products or maintains agricultural land, which is no longer used for production purposes, in good agricultural and environmental condition as defined in Article 2(a) of Regulation (EC) No 1166/2008.

The Law of Agricultural Census in 2010 defines the agricultural holding. The definition did not change since 2003 for the reason of comparison of the results. Agricultural activities are the same as in Annex I of the Regulation No 1166/2008.

2.6. Statistical population

Activities carried out at central level (Agrostatistics Department in the Ministry of Agriculture, Food and Forestry):
1. Draft of the legal and administrative documents for the FSS;
2. Elaboration of the legal acts and administrative records for the FSS;
3. Organisational and methodological guidance;
4. Establishment of the final list of holdings ;
5. Financial and technical support;
6. Data control and data processing, data transmission to Eurostat;
7. Data dissemination to the interested users;
Activities carried out at regional level (regional statistical offices at NUTS 3 level):
1. Examination/correction of the lists of holdings at regional level;
2. Contracts concluded with the census participants – surveyors and operators;
3. Organisation of training of the surveyors and operators;
4. Collection and control of questionnaires;
5. Data entry in a computer module;
6. Report of the payments;
7. Correction of errors in the computer module;


3. Serious deviations from the established timetable (if any)
Delay in announcing a public procurement contract for an on-line data entry system and delays in its application and therefore delay in the deadlines for data entry and control.
3.1. Source data
1. Source of data
Data sources are: a combination of 1 - administrative data from the State Fund Agriculture for the characteristics of Rural development support - from G_2_1 to G_2_17 and Ecological focus area - M_3_1 and 2 - Sample surveys for the remaining characteristics. For data control, imputation in case of refusals and undiscovered owners and the list updates are used:  IACS-SAPS, Bovine register, Integrated information system for animal identification - VetIS, Register of agricultural holders, Organic register and Vineyard Register


2. (Sampling) frame
The main sample was selected by Census 2010, new farms from administrative sources are included in a sample - IACS, Vineyard register, Integrated information system for animal identification - VetIS, farm register. The organic farms and farms identified in statistical studies conducted after 2010 are surveyed exhaustively.

Type of frame: List frame


3. Sampling design
3.1 The sampling design
Single-stage stratified random sampling of holdings is used. The selection within each stratum is purely random. The sampling design is probabilistic.
3.2 The stratification variables
Holdings are stratified by district (NUTS3), farm type and size. 
3.3 The full coverage strata
Considering the low number of holdings in the group of largest farm size and the high variance in the strata with this farm size it was decided to put all holdings with SO equal or greater than 50 000 Euro in an exhaustive “1100” stratum. There are 28 strata “1100” – one for each district. There are 6 073 agricultural holdings in strata “1100”.
Additional exhaustive stratum “1000” stratum was defined in order to improve the precision for some of the variables of interest for which the requested CV of 5% was not achieved with the initial stratification. There are 28 strata “1000” – one for each district. There are 4 503 agricultural holdings in strata “1000”. The criteria are presented here below:
Regardless of the type of farm and if the farm size is less than 50 000 Euro, and if any of the conditions is fulfilled:
'if (SO < 50000 Euro); if (A_3_2_1 > 0 ha); if (A_3_2_2 > 0 ha); if (A_3_2_3 > 0 ha); if (A_3_2_4_1 > 0 number); if (A_3_2_4_2 > 0 number); if (A_3_2_4_3 > 0 number); if (A_3_2_4_4 > 0 number); if (A_3_2_4_5 = 'y'); if (C_99 = 'y'); if (B_1_1_7 > 0 ha); if (B_1_6_2 > 0 ha); if (B_1_6_3 > 0 ha); if (B_1_4 > 0 ha); if ((B_1_6_9 + B_1_6_10 + B_1_6_11) > 0 ha); if (B_1_6_1 >= 5 ha); if (B_1_3 >= 5 ha); if (B_1_7 >= 5 ha); if (B_4_4  >= 5 ha); if (B_4_1_1 >= 5 ha); if ((B_3 - B_3_2) >= 100 ha); if (B_6_1 >= 0.001 ha); if (C_2_99 >= 4 number); if (C_3_2 >= 50 number); if (Buffalo-cows >= 5 number); if (Buffaloes >= 10 number); if (Oil rose >= 4 ha).'

The agricultural holdings from the Organic Register are observed exhaustively . Part of the new holdings, observed in the previous statistical surveys, have been observed exhaustively. These holdings are in the strata "99999"; "90000" with weight 1. Due to the large number of new holdings, some of them were sampled. The sample is designed according to the type of crops and animals and their size - area and number of animals over a certain threshold were observed exhaustively.

Due to the large number of new farms, some of them have been sampled. Their sample is designed according to the type of crops and animals and their size - area and number of animals.
Common land holdings (special holdings created to report common land) were added to the sample in "88888" stratum with a weight equal to one. 

3.4 The method for the determination of the overall sample size
The total observed holdings are 44 423 units of which 30 000 are from the main sample of Census 2010, 14 423 new holdings and holdings from the Bio Register have been added. Of 44 423 totally, 24 283 have a weight of 1.
3.5 The method for the allocation of the overall sample size
Main sample - The allocation method used is Neyman allocation. Variable: SO.
3.6 Sampling across time
No sampling across time. 
3.7 The software tool used in the sample selection
3.8 Other relevant information, if any
Not available.

4.2 Organisational setting on the use of administrative sources
Agrostatistics representatives have been invited to discussions on the unification of the used nomenclatures in the IACS and the Register of agricultural holders. However, it is not possible to use all the statistical definitions for CAP. The nomenclatures of the Organic register were discussed. For statistical purposes, queries were created to allow grouping of VetIS data in line with animal categories observed in statistics.

Law on statistics:

Article 4. (Supplemented, SG No. 81/2005, amended, SG No. 98/2008)
(1) Data necessary for the statistical survey, including individual data, shall be collected directly from the statistical units as well as from administrative sources.

(3) The statistical authorities shall provide the National Statistical Institute with data, including individual data, necessary for development and production of the official national or European statistical information.
(4) To reduce the administrative burden and costs for development and production of official national or European statistical information the National Statistical Institute and the statistical authorities shall receive data, including individual data, as well as aggregate information from administrative sources set up and maintained by other government authorities.

4.3 The purpose of the use of administrative sources - link to the file

4.4 Quality assessment of the administrative sources
  Method  Shortcoming detected Measure taken
- coherence of the reporting unit (holding) Personal Number/BULSTAT The units in administrative sources do not correspond directly to the definition of required statistical units. Difference in the definition of applicant for support in the IACS register and the statistical definition of agricultural holding: In IACS there is not a requirement about single management and it is possible to split one holding by registering different members of the family as different agricultural holders (in the case of family run agricultural holdings) or by separate registering of subsidiaries of the same agricultural holding (in the case of larger holdings). Observed is also the unification of several small holdings into one when applying to IACS. It's difficult to achieve compliance. The correspondence is established after a conversation with the owners and additionally based on collected URN data upon registration in the IACS, but the information is difficult to collect. The most secure EGN / Bulstat identification is sensitive.
- coherence of definitions of characteristics The main characteristics are coherent, for the livestock categories, additional groupings by age and destination will deliver coherence.    
- coverage:      
  over-coverage   Different population coverage. State Fund Agriculture covers all units accepted for subsidizing under the rural development measures. There are cases of some records in Vineyard Register, Bovine register, System for identification and registration of animals, Organic register Not all available data on aid schemes and measures is used. During the survey out-of-date records get detected.
  under-coverage   The registration in IACS is not obligatory. There are agricultural holdings (including larger ones) that don’t apply for subsidies because they do not want or because the eligibility criteria for utilised agricultural area cannot be met (e.g. highland pastures with share of permanently non-eligible elements larger than the allowable percentage). 

Part of the parcels/holding is not eligible for support and therefore not registered in IACS due to the minimum threshold for parcel/holding size. 

Legal grounds for the land use are requested when registering in IACS. Some famers have not (could not) settled the legal grounds for all the agricultural land that they use. In reality they use some land without a legal agreement with the owners. This land is not eligible for support and therefore cannot be registered in IACS. For statistical purposes there is not a requirement about settling the legal grounds for land use and the land for which use farmers don’t have a legal agreement with the owners is in the statistical coverage.

The small units are not part of the administrative sources and so far just the census provides information about them.

4.5 Management of metadata
IACS nomenclatures for crops are stored in electronic format.
4.6 Reporting units and matching procedures
There are problems creating the links between the units: the units in administrative sources do not correspond directly to the definition of required statistical units, the lack of common identifiers, obstacles related to IT issues etc.

Agricultural Producers Support Act (State Gazette No.58 from 22 May 1998 and amendments)
Additional provisions
§ 1. According to the provisions of this law:
1. "Agricultural producers" are physical and legal persons that produce unprocessed and/or processed crop and/or animal production. 

Most often, a link is on an ID number / BULSTAT number.

4.7 Difficulties using additional administrative sources not currently used
No difficulties to report.
3.2. Frequency of data collection
Frequency of data collection
2010-census, 2013 - sample survey, 2016 - sample survey.
3.3. Data collection
1. Data collection modes
The information was collected with a paper questionnaire in a face-to-face interview. At a later stage, an information system has been developed and the data has been introduced.


2. Data entry modes
Physical model of the network in Ministry of Agriculture, Food and Forestry and Regional Statistical Offices.

Information is collected on paper questionnaire through face-to-face interviews. The data is manually entered into the online network by operators.

This network secures the official information and meets the requirements of the Law on Statistics regarding statistical confidentiality and protection of individual data.


3. Measures taken to increase response rates
For the purpose of E-survey, a .NET Framework 4.5.2 based library was be developed to provide a model for reading and processing the surveys and of the collected responses. The .NET model includes in addition to all components of a survey additional variation rules that ensure control of the survey data obtained. Analyzed data from the system are provided in the Analysis and Processing Module.
The .NET library also provides the following options:
· Read an incoming json file describing an E- survey and generate the required .NET model
· Validation of input parameters of an json file describing an E- survey and detection of potential errors in its creation
· Recording of newly created E- surveys in MSSQL database
· Loading surveys from MSSQL database and converting from .NET model back to json file used by survey editor/viewer
· Possibility to change a survey if there are still no results recorded in the database at the time of the change.
· Creating and managing storage tables for an E- survey
· Read json response file on an E- survey and save data in pre-created data tables
· Retrieving data for an E- survey from the base and generating a json data file used by the survey viewer
· Export e- survey from .NET to Microsoft Excel format (* .xlsx)
All functionalities of the system go through multiple validation procedures that guarantee data reliability and data security

- reminder by phone, second visit on-the-spot, additional clarification of the data by phone.

- giving priority to more important, for example large holdings.

3.4. Data validation
Data validation
The individual data is checked through series of logical and mathematical controls. The completeness of the records is checked for the obligatory fields of the questionnaire. The completeness of the units from the list to be surveyed is also checked.

Tools used for data validation:

- manual for interviewers;

- online computer system.

Validation is done at district (local collection centre) and central level (final collection centre) of the MAFF.

3.5. Data compilation
Methodology for determination of weights (extrapolation factors)
1. Design weights
Taking the inverse of the inclusion probabilities 
2. Adjustment of weights for non-response
3. Adjustment of weights to external data sources
4. Any other applied adjustment of weights
There are holdings whose strata defined during the sample drafting do not match their assets at the time of the survey 2016.  Farms with extreme values are deducted from the strata and are included in the aggregate with a coefficient of 1, and the rest of the holdings are recalculated. Due to the exhaustive inclusion of the units from the Organic Register - with coefficient 1, the coefficients of the other holdings are recalculated.

6. Accuracy and reliability Top
6.1. Accuracy - overall
Main sources of error
The main source of error is the coverage error due to the impossibility to updating of the entire list of agricultural holdings and to the dynamic of changes in the Bulgarian farm structure. 
6.2. Sampling error
Method used for estimation of relative standard errors (RSEs)
6.2.1. Sampling error - indicators

1. Relative standard errors (RSEs) - in annex


2. Reasons for possible cases where precision requirements are applicable and estimated RSEs are above the thresholds
The sampling design meets the precision requirements of the Regulation 1166/2008. The a posteriori calculation of the RSEs gives the following deviations:

- for the number of sheep in NUTS2: BG31, BG41. In some holdings from the sample a significant increase of the number of sheep is observed compared to 2010.

These holdings become atypical for the stratum in which they were allocated in 2010.

6.2.1-1. BG Relative standard errors
6.3. Non-sampling error

See below

6.3.1. Coverage error
1. Under-coverage errors
Due to the large dynamics the 2010 population is no longer up to date, new units from other statistical surveys, the bio register and other administrative sources have been added, some of them being sampled due to their large number. 


2. Over-coverage errors
There are units of the total of 2010 with ceased activity. Some of the units have changed their owner, others have ceased their farming activities. Terminated holdings and those below the national thresholds are not included in the units sent to Eurostat. For the aggregate, the coefficients of the other eligible holdings have not been changed following the ineligibility of these units.

No weight correction due to over-coverage.

2.1 Multiple listings 
Big farms operating in more than one NUTS3 are separated and introduced as separate units. The observed holdings are in several lists - Census 2010 - main sample, Organic register - exhaustive, New holdings of statistical surveys created after 2010 - comprehensive and sample lists of farms from other administrative registers. There is a case of duplication of records, but they are eliminated during data collection on-the-spot or during data entry in the computer system and other checks.


3. Misclassification errors
There are holdings whose strata defined during the sample drafting do not match their assets at the time of the survey. Only in the most extreme case the coefficients of extrapolation was changed. These units are subtracted from the initially designated strata and are included in the survey with extrapolation coefficient 1. There are units that changed their geographic position but their weights are preserved.


4. Contact errors
The updated address and contact details of the agricultural holdings were requested from the IACS. 


5. Other relevant information, if any
Not available. Over-coverage - rate

From 44 423 units observed, 12 518 units are ineligible, they have ceased activity or reduced their assets below the threshold or were duplicated on the lists. 163 units were not found, and no data is available for them, because they probably ceased activity. A total of 29% of the observed units were not found, and we have no data on them or they are ineligible. Common units - proportion

[Not requested]

6.3.2. Measurement error
Characteristics that caused high measurement errors
The causes are commonly categorised as:

- Survey instrument: the form, questionnaire or measuring device used for data collection may lead to the recording of wrong values;

Data collection with a paper questionnaire implies technical mistakes. In order to limit these errors multiple controls are set in the computer system during data entry.

During data entry in the software there is no control of the individual data with previous surveys. Some logically related fields get controlled. Example: The sum of the crop area can not be greater than UAA, irrigated area and organic farming area can not be larger than main area, etc.

- Respondent: respondents may, consciously or unconsciously, give erroneous data;

The individual data is compared and clarified if necessary with a second interview. Such interviews are carried out by phone in case significant differences are recorded between the interview data, the administrative crosschecks and data from previous surveys.
Controls of sums and some logically related fields.

- Interviewer: interviewers may influence the answers given by respondents.

Low possibility of such an error. The misunderstanding of some more complicated characteristics such as "F_2_1-Importance of other gainful activities directly related to the holding" can lead to systematic error of interviewers.

Рroblems caused by difficult questions, unclear definitions, sensitive questions etc. which are likely to determine measurement errors.

Characteristics that are complicated for respondents are: tillage methods on outdoor arable land, soil cover on outdoor arable land, crop rotation on arable land, manure application, manure import/export from the holding, household consumes more than 50% of the value of the final production of the holding , labour force.

6.3.3. Non response error
1. Unit non-response: reasons, analysis and treatment
In case of unit non-response the holder is contacted again in order to obtain response. In case the second attempt for interview is not successful the available administrative data is imputed from SAPS and the system for identification and registration of livestock. In other cases the data from the previous survey is used (when it is proven that the unit still has agricultural activity) for imputation or the non-responding unit is replaced (if its weight is higher than 1).

The main reasons for non-response are refusal, not found holdings, too many or unclear questions which lead to unwillingness of the respondent to answer.

Some of the owners/farmers refuse to answer on the questions. The reasons are that they believe that data once given to the administration, for whatever reason, should not be re-collected, and this is an additional burden. These are usually large agricultural holdings, the owners of which are very engaged with a huge workload and cannot spend the time necessary to prepare the data, as their schedule does not allow for an interview. Others are distrustful and refuse to give information, worrying about the purposes for which it will be used. Failures occur in large and small holdings. There are cases where agricultural holders cannot be found because of wrong and outdated addresses (for example, in large populated areas). When the agricultural holding operates and has administrative data and data from other statistical surveys, this data is used and imputed.

6.3.4. Processing error
1. Imputation methods
Imputation method is used in case the respondent refuses to cooperate or can't be found for interview but it is proven that the unit still has agricultural activity. Imputed data is from administrative source (SAPS, system for identification and registration of livestock).

Imputation from administrative data or previous surveys was used for unit non-response.


2. Other sources of processing errors
Single errors detected due to the applicable unit of measure. Due to the use of a new computer online system, the algorithm checks continue.

4. Common land
4.1 Current methodology for collecting information on the common land
The common land is collected from administrative sources and included in records at municipality level.

The position of common land includes pastures and meadows. Permanent crops and crops from arable land are excluded.

A separate questionnaire for common land was used in FSS questionnaire.

The type of tenure for common land units is A_3_1_4 (Common land).

Common land identification in the data can be made through field A_2 = 6 (Legal personality of the holding = Holding is common land).

4.2 Possible problems encountered in relation to the collection of information on common land and possible solutions for future FSS surveys
Common land is expected to decrease in the future. Legislation has been adopted to provide municipal common grasslands to individual livestock holdings.

Co-ordination with other surveys: burden on respondents
The burden of the respondents is due to the large number of characteristics and the specific and difficult matter. The average time required by a respondent for data collection in the questionnaire for Eurostat sent records is 43 minutes.
