Abstract

fetched live from OpenAlex

How diverse are political institutions? Despite the theoretical and political relevance of this question, there is no standard measure of diversity in political institutions, limiting systematic research on diversity of representation. To address this, I introduce the Diversity of Representation Index (DORI), a multidimensional metric that quantifies institutional diversity by considering the variety and balance of represented groups, alongside the proportionality of their representation relative to population size—i.e., their descriptive representation. Using examples from national parliaments in Canada and Germany, and data on women and African Americans in all 50 U.S. state legislatures (2009-2021), I illustrate DORI's application and properties. I demonstrate the significance of assessing diversity and its implications for policy outcomes. DORI offers a valuable tool for representation studies, enabling robust empirical analysis of multidimensional political representation.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
