To ensure national statistical systems meet their obligations to provide open and complete development data, the world needs independent authorities to monitor their performance.

This is one of the founding purposes of Open Data Watch. We created the Open Data Inventory (ODIN) to provide annual assessments of the coverage and openness of official statistics in countries around the world. The ODIN methodology is transparent, reproducible, and consistent with international standards. Since launching the first assessments in 2015, the feedback received from countries and development partners encouraged us to expand our efforts through direct engagement with national statistical offices. Through this direct engagement, we turn our objective assessments into practical policy and technical advice.

Based on demand from organizations focused on specific sectors, we are adapting the ODIN model to sector specific assessments. Our work on an assessment tool for gender data is a prime example. We are also conducting expanded research on national statistics to include microdata as well.


The ODIN website provides access to scores for all rounds of our annual assessments since 2015. The website displays a map of the world showing the countries included in the most recent assessment. Colors indicate the range of the overall ODIN scores by quintiles. Clicking on a country brings up information on each country’s scores and rank. Users can navigate to Country Profile pages for more information on specific countries or use the Rankings and both country and regional comparison pages for broader analysis. Annual reports are available for download. Users can also access and download the ODIN data used to construct scores and ranks.
