MIZORAM

Location and Extent

Mizoram lies between 21⁰ 56’N – 24⁰31’N latitudes and 92⁰ 16’E – 93⁰ 26’E longitudes. Sandwiched between Bangladesh and Myanmar, its location is of strategic significance geographically and politically, and shares a total common international boundary of about 585 kilometres with these two countries. In terms of the size, it may not be so significant as its total area constitutes only 0.64 per cent of the total area of India.

            The tropic of cancer, i.e., 23^o 30’N latitude cuts across the region in Aizawl district at the southern periphery of Aizawl traversing places like Champhai, Chhawrtui, Darlung and Phuldungsei etc. This imaginary line divides the region into two almost equal parts. Mizoram is bounded on the north by Cachar district of Assam and the state or Manipur; on the east and south by Chin Hills of Myanmar; on the west by Chitagong Hill tracts of Bangladesh and the state of Tripura.

            Mizoram has a total geographical area of 21,087 square kilometers.  Its maximum dimentions – north to south is 285 Kilometres, and east to west is 115 kilometres.
