India is politically divided into 28 states and 8 union territories. The states are further divided into administrative divisions like districts, sub-districts, blocks, and villages. Some states are also grouped into geographic zones and regions which have no official status. India's diverse geography leads to different physiographic, climatic, agro-climatic, geological, and disaster-prone regions within the country. Officially delineating the country into various administrative and geographic units aims to better govern and develop the regions according to their characteristics.
