Background 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames • To enlarge the statistical register system to the sector of agriculture (European regulations) • To exploit all information available into administrative sources • To improve the quality of agricultural statistics • To introduce innovations concerning aspects of the Census survey: the use of lists as a support for the survey Paris, November, 2008

  4. The project to build up the Farm Register: phases 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Paris, November, 2008

  5. 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames The input sources description • Specific – sectoral sources • The Integrated Administration and Control System (AGEA) • The System for the Identification and Registration of Bovine Animals and other species (AA.ZZ.) • Lands’ property Incomes (Tax Agency) • The Land registry • Agricultural self-employed workers (Social Security) • Regional agricultural Systems. • General sources • 7. Chambers of Commerce (CCIAA) • 8. Fiscal register (VAT) • Additional statistical sources • 9. BR • 10. The Census of Agriculture 2000 Paris, November, 2008

  6. The Integrated Administration and Control System (AGEA) 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames System of files managed by AGEA i.e. the Italian Paying Agency Recorded unit: agricultural holding obliged to present for any aid application That unit file is constituted the first time a request of premium is presented Updating is made on the basis of yearly requests of aid Paris, November, 2008

  7. The Integrated Administration and Control System (AGEA) 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Information content 1 - identification data: Unique Code of Agricultural Holdings (CUAA code) i.e. the fiscal code of the holder, holder’s name, permanent address or place of residence, VAT number if present, dates of inscription and updating 2 - territorial data: agricultural parcels managed by the farmer, use of each parcel (crops, livestock), hectares invested by type of product, fiscal code of landholders if different from the holder For the 2006/2007 agricultural season: Ident. info = 1,9 millions record Territorial info = 19.3 millions record Paris, November, 2008

  8. Land’s property income 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Data managed by the Tax Agency Recorded unit: tax payer declaring income derived from landlord’s rights and/or agricultural activities Declaration models and their sections Paris, November, 2008

  9. Land’s property income 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames In figures … Paris, November, 2008

  10. The System for the Identification and Registration of Bovine Animals and other species (AA.ZZ.) 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Data managed by the Ministry of Welfare Recorded unit: animals and their holders with the scope to preserve public health. The covered animal species are bovines, pigs, sheep and goats, poultry, equines The national database of Bovine Animals realized in accordance with the EC n. 1760/2000 for the setting up of a System for the Identification and Registration of Bovine Animals, is the only fully operative register up to date For sheep and goats the existing regulation (EC n. 21/2004) to set up a register is not yet fully operative No regulations for others species Paris, November, 2008

  11. The System for the Identification and Registration of Bovine Animals and other species (AA.ZZ.) 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames In figures … 1) Bovines =239,304 2) Speep and goats =148,894 3) Pigs =89,332 4) Poultry =18,062 5) Equides =29,706 Paris, November, 2008

  12. The Land registry 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Unit information: 1) parcels referring to land: parcel identification codes, parcel characteristics like “soil quality” (i.e. land devoted to vineyard or sowable ground), hectare, estimated agricultural income 2) their owners: natural person -name, surname, sex, birth date, fiscal code – juridical person – name, fiscal code 3) their ownership’s title: land’s rights (property, usufruct), property share and property settlement. Paris, November, 2008

  13. The Land registry 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames • Many advantages….but also many problems such as: • files organized by municipality • enormous variety of information difficult to treat • the parcel’s owner cannot be the holder • updating is not homogenous • soil quality could not be updated • difficult to identify agricultural uses only Paris, November, 2008

  14. summary 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Characteristics of sources – units and coverage T=Total – Ts=Total for the reference population – P=partial Paris, November, 2008

  15. The production process 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Phase 1 – The pre-treatment of each administrative file Phase 2 – The physical integration: the intra-archive link the link among different archives Phase 3 – The units identification process Prototype list Paris, November, 2008

  16. The production process 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames • The integration strategy: • AGEA, used as pivot • Three initial basic sources: AGEA-AA.ZZ.-Land’s property income, treated according to a linkage process that uses all available matching keys so that links among records can be classified: • Direct link: a match between the primary key of AGEA and the primary key of the other source. • Indirect link: a match between the primary key of AGEA and the secondary keys of the other source. • Complex link: a match between the secondary key of AGEA and the primary/secondary key of the other source. • c) Hierarchical integration of the other 6 sources • d) Land registry integrated by parcel and owner’s fiscal code Paris, November, 2008

  17. The pre-treatment process 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames AGEA – Unit identification Primary key= CUAA Secondary key = landowner’s fiscal code Paris, November, 2008

  18. The pre-treatment process 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Land’s property income – Unit identification Primary key= taxpayer’s fiscal code Secondary keys = dependent relative and participated firm’s fiscal code Paris, November, 2008

  19. The integration process 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Structure of matched records: A potential agricultural unit corresponds to any integrated record (single record i.e. a CUAA/Fiscal code) or to any group of records (a cluster). In the latter case the link among fiscal codes must be verified on the field. Paris, November, 2008

  20. The unit’s characters 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames • Unit’s attributes: identification (i.e location) and stratification variables: • taken from input sources: i.e. agricultural utilized area (hectares) • derived from deterministic methods: indicator of existence, eligibility degree, belonging to a cluster (familiar links) • Problems: measurement errors, missing data, coverage • Decision: No threshold applied, any unit belongs to the prototype list BUT with different quality i.e. with different signals to be an agricultural holding Paris, November, 2008

  21. The quality survey 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames • To test on the field the prototype-list with the aim to (re)-define the correct statistical model to set up the final pre-census list for 2010 • Checks to evaluate: • the correct use of administrative sources • the integration methodology • the units’ identification • the criteria for data imputation • The statistical methodologies to identify the census universe Paris, November, 2008

  22. The quality survey 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames • The prototype list is composed by 7 sub-lists: • the integrated AGEA-based list (1) • the integrated not AGEA-based list: • Residuals of land’s property income with agricultural signals (2) • Residual of CCIAA / VAT with agricultural activity, secondary or primary (3) • Residual of CCIAA without agricultural activity but with lands from the land registry (4) • Residual of CCIAA / VAT with agricultural activity but with lands from the land registry (5) • Otherland’s property income records without agricultural signals but with lands from the land registry (6) • Residual of lands from the land registry only (7) • The probability a unit be an agricultural holding decreases starting from list 1. Paris, November, 2008

  23. The quality survey 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Constrains: a) 80 municipalities chosen on the basis of the national agricultural structure b) 120,000 units created by the prototype list c) Sample size: 16,000 Sample design: two stages stratified sample 1 stage: chosen municipalities 2 stage: units are chosen according to an allocation method proportional to each sub-list size Purpose: to select a high percentage of less “elegible” (uncertain) units (70% of the sample) survey technique - face-to-face interviews carried out in the unit’s residence place asking information about all lands and livestock Paris, November, 2008

  24. Timetable and future work 21th Meeting of Wiesbaden Group on BR – Roundtable on Business Survey Frames Timing First prototype list realization - end September 2008 (agricultural data referred to years 2006/2007) Quality survey launched beginning November 2008 Results of the survey foreseen - end March 2009 Updated second prototype list – end April 2009 Ex post reconciliation between survey results and the second prototype list– by June 2009 Pre Census final list – by April 2010 Census of Agriculture – October 2010 After…The Farm Register Paris, November, 2008
