Bihar has 243 seats in its Legislative Assembly, each electing one Member of the Legislative Assembly (MLA). These seats are nested within 40 Lok Sabha (Parliamentary) constituencies, meaning each parliamentary seat comprises several assembly seats. What this really means is that the state‑level electoral map is directly linked and aligned with national‑level representation. Organizing the assembly constituencies by their parliamentary constituency helps trace how state‑level politics connect with national politics, how local demographics and issues aggregate up, and gives a clearer view of electoral geography across Bihar.
