New projects

The purpose of this section is to notify users of innovations regarding the projects for statistical operations that are in a preparatory phase, and regarding the methodological changes that might affect the operations performed by the INE. This also includes those activities that the INE carries out in order to provide the necessary infrastructure to statistical production or in order to meet the requirements set out in national and international regulations.

New statistic operation projects

  • Construction Production Index (CoPI)

    • Objective: The aim of the Construction Production Index (CoPI) is to measure the monthly change in the activity of the companies that form part of the construction industry in Spain, based on their added value. It replaces the Construction Industry Production Index Survey (CoIPI), which had been produced monthly by the Ministry of Transport and Sustainable Mobility (MTSM) until December 2025.
      The transfer of this statistical operation from the MTSM to the INE is the result of an accord between both parties included in an Agreement signed on 21 May 2025, whereby both the Construction Industry Structure Survey and the Construction Industry Production Indices become the responsibility of the INE in all of its production phases. In the case of CoIPI, it is renamed CoPI.
      The CoPI is produced in accordance with Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 concerning European business statistics, repealing ten legal acts in the field of business statistics and Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020, laying down technical specifications and modalities pursuant to Regulation (EU) 2019/2152 of the European Parliament and of the Council concerning European business statistics that repealed ten legal acts in the field of business statistics, making it compulsory for all Member States to produce this statistical operation.
      The CoPI will be published for the first time on 13 March 2026, with data referring to the previous January.

      Dissemination date: March 2026. Technical project

  • Social Economy Satellite Account

    • Objective: The Social Economy Satellite Account (SEAS) statistic is established as an annex to the central framework of the System of National Accounts (SNA) and aims to provide a complete and comparable picture of what is called the third sector or social economy sector, covering three components: non-profit institutions (NPIs), related institutions and voluntary work.

Projects for the improvement and adaptation of existing ones

  • National Classification of Economic Activities 2025 (CNAE-2025)

    • Objective: the revision of the National Classification of Economic Activities (CNAE) responds to the need to reflect changes in economic and technological structures and, thus, to ensure that the statistics collected maintain their relevance and faithfully represent the economic reality of the moment. The publication of the CNAE-2025 culminates a 5-year process in the course of which its international equivalent, the International Standard Industrial Classification (CIIU), and its European analogue, the Statistical Classification of Economic Activities (NACE), have been revised, in such a way that a high degree of coherence has been maintained between said classifications. The CNAE-2025 will be published in the standards and classifications section of the National Institute of Statistics (INE) website.

      Effective date: from 1 January 2025 to 1 January 2031. Technical project

  • Statistical revision of the operations of the INE Ntational Accounting 2024

    • Objective:Therefore, the next Spanish National Accounting Statistical Revision, published this year, 2024 (RE-2024) meets the aforementioned need to periodically update the sources and methods of estimation used in its compilation. All results of the operations that make up the national and regional accounts disseminated by the INE from September 2024 will incorporate this revision. Furthermore, this process has been implemented in coordination with the Bank of Spain for financial accounts and balance of payment and investment position statistics, and with the Comptroller General of the State (IGAE) for the accounts of Public Administrations.

      Effective date: it will commence in September 2024. Technical project

  • Intensification of the use of administrative records in the Structural Business Statistics

    • Objective: This project is part of the strategic line of intensification of the use of administrative records included in the National Statistical Plan 2021-2024. In addition to responding to the new requirements of Regulation 2019/2152 on Business Statistics, this action makes it possible to reduce the statistical burden on companies and improve processes for the production and dissemination of information.

      Application date: 2022-2024. Technical project

Modernisation of information systems

  • Statistical interoperability node

    • Objective: To lay the legal and technical foundations to set up a Statistical Interoperability Node through the InterSTAT working group within the Interterritorial Statistical Committee (CITE). This project sets out to simplify the exchange of data for statistical purposes nationwide to optimise public decision-making and interoperability with other bodies of the European Union.

      Effective date: September 2024. Project

  • Online register

    • Objective: To modernise the current continuous register system. This system will incorporate new features that will improve its management: territorial information will be stored separately from population information, a Housing Identification Code (CIV) based on the catastral reference will be incorporated into each dwelling and a monthly file-based exchange system will be replaced with a real-time exchange of information based on web services.

      Effective date: fourth quarter 2026. Project
