About the Book: Ratios in the Republic: Voter Choice Patterns in the World’s Largest Democracy by Devi Prasad Semwal examines India’s General Elections from 1951–52 to 2024, asking why millions of voters repeatedly produce recognisable electoral patterns. Drawing on behavioural genetics, population ecology and political analysis, the book explores how individual predispositions interact with social, economic and political conditions to shape large-scale voting outcomes. Rather than focusing solely on parties, leaders and campaigns, it offers an interdisciplinary perspective on democracy and voter behaviour, inviting readers to consider the deeper forces behind electoral choices in India.
