There are four main types of rural settlements in India: clustered, semi-clustered, hamleted, and dispersed. Clustered settlements are compact villages with houses built close together, while semi-clustered settlements are partially clustered with some houses located farther away. Hamleted settlements consist of separate housing units under a common name. Dispersed settlements involve isolated homes or small hamlets scattered over remote or rugged terrain. Physical geography, social factors, defense needs, and resource availability all influence the type of rural settlement in different areas of India.
