Abstract

This paper introduces the concept of a two-state index — a composite metric designed to quantify and compare the relative performance, policy alignment, and societal outcomes between two distinct political entities (e.g., nation-states, regions, or autonomous territories). Unlike multilateral indices (e.g., Human Development Index, Democracy Index), a two-state index allows for direct, symmetrical comparison, highlighting convergence or divergence across time. We propose a methodological framework and apply it to three illustrative case studies: (1) North and South Korea, (2) Haiti and the Dominican Republic, and (3) East and West Germany (historical). The paper discusses index construction, normalization challenges, and interpretive limits, concluding with recommendations for policy and academic use. index of 2 states

Methodology

• Storage: 1000 bits = 125 bytes vs. 3 integers = 12 bytes (actually larger for sparse sets, but smaller for dense sets).
• Operations: Union (OR), Intersection (AND), Membership (test bit) are O(1) or O(n/word_size).
