Open Data Inventory (ODIN)

The Open Data Inventory (ODIN) is a global assessment of the coverage and openness of official statistics. Covering nearly 200 countries, ODIN shows whether important social, economic, and environmental data are available and how well published data meet open data standards that make them easier to access and reuse.

National statistical offices, policymakers, development partners, researchers, civil society, and other data users can use ODIN to identify gaps, compare progress, and find opportunities to strengthen national data systems.

About ODIN

Reliable and accessible official statistics are essential for understanding people’s lives, guiding public policy, tracking development, and holding institutions accountable. But data are only useful when they are available, sufficiently complete, and published in ways that allow people to find, understand, and reuse them.

Since its launch in 2015, ODIN has provided an independent and consistent way to assess these qualities across countries. ODIN measures coverage—whether important statistics are available, including data over time, for different population groups, and at subnational levels—and openness—whether published data can be easily accessed and reused through open formats, appropriate metadata, download options, and open licensing. Country profiles allow users to explore results in detail, compare performance, identify strengths and gaps, and review recommendations for improvement.

ODIN has grown into one of the world’s most comprehensive assessments of official statistics. The current 2026/27 assessment covers 198 countries and evaluates more than 60 indicators across 23 categories of social, economic, and environmental statistics. ODIN also contributes directly to global monitoring: the ODIN Coverage Index is one of the official measures used for Sustainable Development Goal indicator 17.18.1 on statistical capacity.

What ODIN does

Assessment & Benchmarking

ODIN independently assesses the coverage and openness of official statistics using a common methodology across countries. Country scores and profiles allow users to identify gaps, track progress over time, compare results, and understand where changes in data production or publication practices could make official statistics more complete, accessible, and useful.

Country Support & Engagement

ODIN is designed to support improvement as well as measurement. National statistical offices are invited to review preliminary assessments, provide feedback, and identify additional official data sources. Open Data Watch also provides technical assistance, workshops, training, and country-level support that help institutions understand their results and turn assessment findings into practical improvements.

Research & Advocacy

ODIN provides a global evidence base for understanding progress and persistent gaps in official statistics. Open Data Watch uses ODIN findings to produce global reports and thematic research, examine emerging issues affecting data systems, and advocate for policies and investments that improve the availability and openness of official data.

ODIN findings also contribute to international monitoring, including Sustainable Development Goal indicator 17.18.1.

Our Role

Open Data Watch created ODIN and leads its methodology, assessments, quality review, analysis, and publication. ODIN is designed as an independent assessment, while giving national statistical offices an opportunity to review preliminary findings and provide information that can improve the accuracy and completeness of their assessments. Open Data Watch retains responsibility for applying the methodology and determining final results.

ODIN is supported by the William and Flora Hewlett Foundation.
