Boix-Miller-Rosato Dichotomous Democracy Coding, 1800-2020

Carles Boix, Michael K. Miller, and Sebastian Rosato's dataset provides a dichotomous classification of democracy for 222 countries from 1800 to 2020. This version updates the original 2007 data and includes a measure requiring a level of female suffrage. The data is maintained by Michael K. Miller of George Washington University.

Use Cases

• Analyzing global democratization trends over time based on the dichotomous coding from 1800 to 2020.
• Studying the relationship between female suffrage and regime type based on the included measure.
• Conducting comparative historical analysis of political regimes across 222 countries.
• Validating or comparing other democracy indices using a long-term, dichotomous classification.

Strengths

• Covers 222 countries, providing a global scope.
• Spans 220 years (1800-2020), enabling long-term historical analysis.
• Includes a specific measure of democracy tied to female suffrage.
• Updates and extends a previously published academic dataset.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
