Three decades of harmonized election returns for Rome, Italy, from 1993 to 2023, covering municipal, national, and European elections.

Use Cases

• Analyzing long-term trends in voter participation and abstention based on the harmonized turnout time series.

• Measuring electoral volatility and realignment timing with Pedersen's volatility index and cross-correlation tests.

Strengths

• Based on official election returns from the Italian Ministry of the Interior (Eligendo).
