Maritime Security Index | Data File & Code Book

The Stable Seas Maritime Security Index uses dozens of data points to measure each country’s threats and capacities across nine maritime security issue areas. All of the issue scores comprise multiple data sources, and some rely on nested hierarchies of components and subcomponents. These calculations represent the best available information about complex and under-reported activities occurring in expansive and remote maritime regions. Index scores are derived from original research and information from external stakeholders and secondary sources. Quantitative data, surveys of subject-matter experts, and qualitative information are used to compile these scores. Some issue-area scores necessarily reflect operationalizations of concepts or best-faith estimates rather than precise numbers.
