Kalat was notified as a district on February 3, 1954. At that time Khuzdar and Mastung districts were sub-divisions of Kalat (which then also included Bolan, Jhal Magsi and Naseerabad (Dera Murad Jamali); these were separated in 1965 as Kachhi District). Khuzdar became a separate district by notification of 1 March 1974, while Mastung was announced to be separate district on 18 February 1992. The district draws its name from the ancient city of Kalat. The old name of the district headquarters was Kahan. The current district consists of two sub-divisions, i.e. Kalat and Surab, five tehsils: Kalat Mangochar, Johan, Gazgz, and Surab, 81 patwar circles and 614 mauza (villages).
The climate is arid, hot in summer and cold in winter, with most rainfall occurring in the winter. The terrain is mountainous with several valleys and one main river, the Moro. The main economic activities are agriculture and livestock farming.
The district is administratively subdivided into the following tehsils:
According to the census of 1995, 89% of the population speak the Brahui language and 10% the Balochi language; presumably, this refers to the proportions of the population that name the said language as their native tongue. Over 98% of the population is Muslim. There is a small Zikri minority. The major Baloch tribes of the district are Dehwar, Mengal and Zehri. (ALIZAI)
