Three sub-divisions and four blocks: how Champhai district is put together
Background
Central road work reaching Mizoram's eastern hills keeps Champhai district in view. The district came into existence on 12th December 1997, in the north-east corner of the State. Its administration divides it into three sub-divisions, Champhai, Ngopa and Khawzawl. Below those sub-divisions sit four blocks. Champhai town is the administrative headquarters of the district. The district has Manipur on its north and Myanmar on its east and south. Champhai is therefore a good single example of how administration in Mizoram is layered, from district to sub-division to block. The district's own administration gives the date of formation, the sub-divisions and the blocks in that order.
In plain words
Sub-division Administrative tier below a district — A unit between the district and the block in Indian district administration.
