2025 OPEN DATA MATURITY REPORT

The 2025 open data maturity (ODM) assessment evaluated the maturity of countries in the field of open data. In particular, the assessment measured the progress of European countriesin making public sector information available and stimulating its reuse, in line with the open data directive (Directive (EU) 2019/1024). A total of 36 countries participated in this 11th consecutive annual assessment, including the 27 EU Member States, 3 European Free Trade Association (EFTA) countries (Iceland, Norway and Switzerland) and 6 candidate countries (Albania, Bosnia and Herzegovina, Montenegro, North Macedonia, Serbia and Ukraine). This report aims to help readers better understand the level of ODM of the participating countries, to identify areas for improvement and to enable participating countries to learn from one another. As an annual publication, the ODM report also captures the progress made by countries over time, with the 2025 report providing the latest information. Moreover, it gives an overview of best practices implemented across Europe that could be transferred to other national and local contexts.
