Progress in open data: The 2025 Open Data Maturity assessment is now
available
The 2025 OPEN DATA MATURITY (ODM) assessment
[https://data.europa.eu/en/open-data-maturity/2025] has been
published, providing the latest overview of how European countries are
advancing in making public sector information more accessible,
reusable and impactful. This 11th edition assesses 36 COUNTRIES,
including all 27 EU Member States, three members of the European Free
Trade Association and six candidate countries. The ODM continues to
serve as an essential reference for tracking progress, identifying
emerging trends and supporting peer learning across Europe. 

Progress is visible across all four dimensions of the assessment:
policy, portal, data quality and impact. POLICY
[https://data.europa.eu/en/open-data-maturity/2025#dimensions/dimension_policy]
remains the strongest dimension, with countries further strengthening
long-term governance structures and updating their national strategies
more regularly and continuing implementation of the high-value
datasets
[https://data.europa.eu/en/publications/datastories/high-value-datasets/]
Regulation. National PORTALS
[https://data.europa.eu/en/open-data-maturity/2025#dimensions/dimension_portal]
also show renewed progress after last year’s dip, with more features
to help users find and access datasets, stronger support for data
providers and clearer long-term plans for portal sustainability.
Improvements in data QUALITY
[https://data.europa.eu/en/open-data-maturity/2025#dimensions/dimension_quality]
are driven by better metadata practices, wider use of European
standards such as DCAT-AP and more complete time series. Meanwhile,
the IMPACT
[https://data.europa.eu/en/open-data-maturity/2025#dimensions/dimension_impact]
dimension continues to grow gradually as more countries develop ways
to measure how open data benefits society, environment, and the
economy. 

Open data [https://data.europa.eu/en] remains a cornerstone of
Europe’s digital transformation. By making public sector information
easier to find, use and trust, countries enable innovation,
transparency and better public services. The report highlights
practical steps
[https://data.europa.eu/en/open-data-maturity/2025#recommendations],
from multi-stakeholder governance to user-centred portal design, that
help strengthen Europe’s open data ecosystem. It also showcases
real-world examples of open data driving tangible impact: using health
data to improve hospital accreditation processes, reusing geospatial
and heritage datasets for smarter urban planning, transforming census
data into engaging digital art to explore social trends, providing
students with safe AI learning environments, helping farmers reduce
fertilizer use and cut greenhouse gas emissions, and powering
predictive models that support public health planning and emergency
response. The 2025 Open Data Maturity assessment is now available
through an interactive digital platform, offering users a hands-on
experience with country performance, trends over time, tailored
recommendations, and dimension-specific insights.
