Abstract:
Cross-national and within-country research on electoral behavior has been constrained by the coarseness of available election data. Existing resources aggregate to the constituency or country level, lack spatial information, or cover only a small set of well-documented democracies. The Small-Area Global Elections (SAGE) dataset collects, geocodes, and harmonizes lower-house parliamentary and presidential returns for 110 countries and territories from 1948 to 2025, at the smallest unit each electoral authority publishes. It spans 585 country-elections and roughly ten billion votes cast across more than eight million units, and is at the polling station level in more than two-thirds of cases. Returns are released in a single long-format schema with standardized party identifiers that link to major comparative datasets, and every unit carries coordinates and, where available, boundary polygons. SAGE opens up spatially and comparatively fine-grained analysis of elections from consolidated democracies to hybrid regimes.
