Commission Implementing Regulation (EU) 2018/1799 of 21 November 2018 on the establishment of a temporary direct statistical action for the dissemination of selected topics of the 2021 population and housing census geocoded to a 1 km2 gridText with EEA relevance.

Commission Implementing Regulation (EU) 2018/1799 of 21 November 2018 on the establishment of a temporary direct statistical action for the dissemination of selected topics of the 2021 population and housing census geocoded to a 1 km2 grid (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 223/2009 of 11 March 2009 on European statistics and repealing Regulation (EC, Euratom) No 1101/2008 of the European Parliament and of the Council on the transmission of data subject to statistical confidentiality to the Statistical Office of the European Communities, Council Regulation (EC) No 322/97 on Community Statistics, and Council Decision 89/382/EEC, Euratom establishing a Committee on the Statistical Programmes of the European Communities OJ L 87, 31.3.2009, p. 164. , and in particular Article 14(2) thereof, Whereas: (1) The dissemination of Union-wide harmonised census topics on a constant area grid, in particular on a 1 km2 grid, is a key European statistical output for future policy-making and census strategies by the Member States. (2) Pursuant to Article 14(1)(b) of Regulation (EC) No 223/2009, the Commission may decide in specific and duly justified cases, in order to meet unexpected needs, on a temporary direct statistical action which shall fulfil conditions laid down in Article 14(2) of that Regulation. (3) This temporary direct statistical action should provide for data collection covering one reference year. All Member States should be able to produce univariate census data geocoded to a 1 km2 grid at the reference date for the 2021 population and housing census; the Union should also make financial contributions to National Statistical Institutes and other national authorities to cover the incremental costs incurred by them. This action is supported by a cost-effectiveness analysis and an estimate of overall incremental production costs provided by the Commission. (4) This action is justified by a common need across the Union for reliable, accurate and comparable information on population distribution with sufficient spatial resolution, founded on harmonised output requirements and intended in particular for pan-European regional policy-making. (5) Harmonised, spatially resolved demographic information across the Union is available, and the objective is to disseminate one dataset per Member State, containing selected topics of the 2021 population and housing census geocoded to a 1 km2 grid. There is no additional burden on respondents as all necessary information will be obtained from the 2021 census data. (6) In particular, in order to achieve comparable harmonised outputs across the Union, a Union-wide constant area grid consisting of 1 km2 cells needs to be determined. Furthermore, the specific topics and their breakdowns as well as the detailed programme to be disseminated on this 1 km2 grid need to be established. Finally, it is necessary to specify the required spatial and statistical metadata for such a dataset.

(7) Directive 2007/2/EC of the European Parliament and of the Council Directive 2007/2/EC of the European Parliament and of the Council of 14 March 2007 establishing an infrastructure for spatial information in the European Community (INSPIRE) (OJ L 108, 25.4.2007, p. 1). and related Commission Implementing Regulations lay down the required metadata Commission Regulation (EC) No 1205/2008 of 3 December 2008 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards metadata (OJ L 326, 4.12.2008, p. 12). , data format Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services (OJ L 323, 8.12.2010, p. 11). , and network services Commission Regulation (EC) No 976/2009 of 19 October 2009 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards the Network Services (OJ L 274, 20.10.2009, p. 9). for the dissemination of spatial data. In particular, point 1 of Annex III covers possible statistical grid systems for spatial data dissemination and, according to point 10 of Annex III, is applicable to spatial datasets under the theme Population distribution — demography. (8) Regulation (EC) No 763/2008 of the European Parliament and the Council Regulation (EC) No 763/2008 of the European Parliament and of the Council of 9 July 2008 on population and housing censuses (OJ L 218, 13.8.2008, p. 14). and related Commission Implementing Regulations establish common rules for transmission of the 2021 census data, in particular the reference year and the required metadata Commission Regulation (EU) 2017/712 of 20 April 2017 establishing the reference year and the programme of the statistical data and metadata for population and housing censuses provided for by Regulation (EC) No 763/2008 of the European Parliament and of the Council (OJ L 105, 21.4.2017, p. 1). , the technical specifications of the census topics and their breakdowns Commission Implementing Regulation (EU) 2017/543 of 22 March 2017 laying down rules for the application of Regulation (EC) No 763/2008 of the European Parliament and of the Council on population and housing censuses as regards the technical specifications of the topics and of their breakdowns (OJ L 78, 23.3.2017, p. 13). , and the technical format Commission Implementing Regulation (EU) 2017/881 of 23 May 2017 implementing Regulation (EC) No 763/2008 of the European Parliament and of the Council on population and housing censuses, as regards the modalities and structure of the quality reports and the technical format for data transmission, and amending Regulation (EU) No 1151/2010 (OJ L 135, 24.5.2017, p. 6). . (9) Member States should transmit their validated data and metadata in electronic form, in an appropriate technical format to be provided by the Commission. The Statistical Data and Metadata eXchange (SDMX) initiative on statistical and technical standards for the exchange and sharing of data and metadata, on which the Census Hub is based, was launched by the Bank of International Settlements, the European Central Bank, the Commission (Eurostat), the International Monetary Fund, the Organisation for Economic Cooperation and Development (OECD), the United Nations and the World Bank. For the exchange of official statistics, SDMX and the Census Hub provide statistical, technical and transmission standards. A technical format in accordance with those standards should therefore be introduced.

(10) The Commission (Eurostat) hosted a project on Harmonised protection of census data in the ESS, which delivered good practices and implementation guidelines for the harmonised disclosure protection of 1 km2 grid data. (11) The measures provided for in this Regulation are in accordance with the opinion of the European Statistical System Committee, HAS ADOPTED THIS REGULATION:
