Management of territorial units over time Torbiörn Carlquist Statistical Office of the European Commission Eurostat - unit E4 / GISCO BECH D3/710 L-2920 Luxembourg +(352) 4301-35453 e-mail: Torbioern.Carlquist@cec.eu.int

Territorial units NUTS only for EU Member States “Statistical Regions” for candidate countries 3 regional levels - proper NUTS 2 local levels Level 5 = commune, municipality (obec, gmina, telepules, orasul, obcinah, vald/linn, pagast, seniunija, naseleni mesta etc.)

Why? SIRE data base for local units GISCO - maps Regional policy: eligibility for structural funds Competition policy: to check national regional support Agricultural policy

SIRE data base Systeme Europeen d’Information Infra-Regionales Population census data 1981-1991-2001 30 variables Defined in Table Programme for the Population Census

GISCO Data set with commune boundaries SABE= Seamless Administrative Boundaries for Europe Versions: 1981, 1991, 1995, 1997 Communes in 29 countries 2001 version of CM will correspond to census date in each country

NUTS code Maintained by Eurostat 3 regional levels 2 local levels Harmonised code structure Link between SIRE and GISCO Small modification in 2001 http://europa.eu.int/comm/eurostat/ramon/

Statistical Regions For non-EU countries New publication soon 3 regional levels 2 local levels Harmonised code structure Link between SIRE and GISCO http://europa.eu.int/comm/eurostat/ramon/

Changes to communes Eurostat needs to keep track of changes Maintains the NUTS 5 codes Very frequent changes in some countries No changes at all in other countries Impact on NUTS 3 boundaries Not possible to define threshold for “significant change”

NPS Application which handles nomenclature changes Developed for “External Trade” NUTS Management System Special input format required CONC/MODA

CC local units First collection of level 5 units in 2000 02/17/98 CC local units First collection of level 5 units in 2000 1989/91, 1997, 1999/2000 National code and name Total population Land surface area Linked to SABE 97 (commune boundaries) Missing: LT (sent level 4 data) and RO, CY 4

PHARE 2000 project SIRE part A 02/17/98 PHARE 2000 project SIRE part A External contractor to be chosen Project will start in 2002 “BOUndary report” Transmit census data for 1990/91 Transmit evolution of local units (CONC/MODA) 4

PHARE 2000 project SIRE part B 02/17/98 PHARE 2000 project SIRE part B Validate census data Load data into SIRE and Census db Integrate the CONC/MODA files with nomenclature change into NPS Create community codes on all levels 4

”BOUndary” report First BOUndary report for EU-12 (1994) 02/17/98 ”BOUndary” report First BOUndary report for EU-12 (1994) Addition for 3 new EU members (1996) Updates in “pilot studies” (FI, NL,UK,DE) Inventory of territorial classification and geographical boundaries System for maintenance of local unit Will draw on results from ABDS project Missions to all CC 4

CC Population Census 2001 Population Census “2001” 02/17/98 CC Population Census 2001 Population Census “2001” Table Programme: 40 tables 3 tables for local units (level 5) Data for CC will be collected in the same framework as for the Member States 4

CC Population Census 1991 Population Census “1990/91” 02/17/98 CC Population Census 1991 Population Census “1990/91” Old Table Programme 1 table for local units (level 5) Data for CC will be collected retroactively within the PHARE project in 2002 4

02/17/98 CC CONC/MODA Need to track changes in local units over time 1989/91- 2002 and onwards CONC/MODA format Build up a system at each NSI in CC for reports to Eurostat Can be delivered as Excel or text files 4

CONC/MODA CONCordance between old and new units MODificAtion of units 02/17/98 CONC/MODA CONCordance between old and new units MODificAtion of units Add Delete Modification (of label or national code) No info on the size of transferred units All changes of local units are to be reported 4

02/17/98 Conclusions Candidate countries will be asked to submit lists of changes of local units from 1991- CONC/MODA format shall be used PHARE project is next step of co-operation BOUndary reports Collection of census data 1990/91 4

Thank you for your attention! Any questions ???
