India
India is a federal union comprising 29 states and 7 union territories. All states, as well in addition to the union territories of Puducherry and the National Capital Territory of Delhi, have elected legislatures and governments following on the Westminster system of governance. The remaining five union territories are directly ruled by the centre through appointed administrators. In 1956, under the States Reorganisation Act, states were reorganised on a linguistic basis. Since then, their structure has remained largely unchanged. Each state or union territory is further divided into administrative districts. The districts are further divided into tehsils and ultimately into villages.
Administrative divisions of India
Some states consist of regions, which have no official administrative governmental status. They are purely geographic regions; some correspond to historic countries, states or provinces. A region may comprise one or more divisions, averaging about three divisions per region. However, the boundaries of the regions and the boundaries of the divisions do not always coincide exactly. So far there has been no movement to give the regions official administrative status. If this was to be done, it would presumably require that the boundaries of the regions be slightly modified so that they correspond exactly with their constituent districts.
