Data Sheet 2_Crosstown traffic: the evolution of the Roman political system (1993–2023).cs

Harmonized election data for Rome, Italy, covering three decades from 1993 to 2023. The dataset includes indicators for turnout, party competition, electoral volatility, and personalization across municipal, national, and European electoral arenas. It was compiled by Roberto De Rosa using official returns from the Italian Ministry of the Interior.

Use Cases

• Analyzing long-term trends in voter participation and abstention based on turnout data.
• Studying party system fragmentation and realignment based on the Effective Number of Electoral Parties (ENEP) indicator.
• Measuring electoral stability and change based on Pedersen's electoral volatility index.
• Investigating the personal vote in mayoral elections based on the mayor–list gap indicator.
• Comparing the timing of political shifts in a capital city versus national aggregates based on cross-correlation analysis.

Strengths

• Data covers a 30-year time span from 1993 to 2023.
• Includes harmonized indicators for four distinct electoral arenas (municipal, national, regional, European).
• Based on official election returns from the Italian Ministry of the Interior.

Limitations

• The dataset is very small (542 bytes), suggesting it contains aggregated summary statistics rather than raw election returns.
• Column-level documentation is absent; field semantics must be inferred after download.
