Roman Election Indicators for Municipal, National, and European Elections (1993–2023)

Rome, Italy, provides the geographic scope for this dataset of electoral indicators spanning three decades. The data, created by Roberto De Rosa, includes harmonized time series on turnout, party competition, volatility, and personalization across municipal, national, and European elections from 1993 to 2023. It was last updated in April 2026.

Use Cases

• Analyzing long-term trends in voter participation based on turnout and abstention indicators.
• Studying party system fragmentation and realignment using the Effective Number of Electoral Parties (ENEP) and Pedersen’s volatility metrics.

• Comparing the timing of electoral changes across different political arenas (municipal, regional, national, European).
