Defines: "Committee" (a Wards Committee under Article 243S), "district", "Metropolitan area" (population 10 lakh+, spanning multiple Municipalities/Panchayats, notified by the Governor), "Municipal area", "Municipality" (an urban self-government institution under Article 243Q), "Panchayat", and "population".
This sets out the basic vocabulary for urban local self-government, paralleling Article 243's definitions for the rural Panchayat system - notably introducing "Metropolitan area", a distinct category for large urban agglomerations spanning multiple municipal bodies.
A "Metropolitan area" designation (population 10 lakh - one million - or more) is what triggers the need for a Metropolitan Planning Committee under Article 243ZE, distinct from the planning arrangements for smaller towns.
