India has 28 states and eight union territories, which are divided into divisions comprising several districts. Subdistricts are most commonly referred to as tehsils, which comes under a sub-division of a district. The current terms have replaced earlier geographical terms, such as pargana and thana.
Most subdistricts in India correspond to an area within a district including the designated city, town, hamlet, or other populated place that serves as its administrative centre, with possible additional towns, and usually a number of villages.
