Its Population is about 4000 persons. Major clans are Khokhar, Rajput, Arain, Syed, Khichi, Awan, Mangla Demys, Bloch (Khan) and Afghani Pathan. Historically, the majority of people living in this village are farmers who own their land, but as times change, these people have been progressively going into business. The village is still entirely agricultural. Its major crops are wheat, sugar cane, cotton, barley, oats, pulses and citrus. It is easily accessible from major cities via Sargodha Road, Faruka Road, Barana Road and a railway track. The railway track was laid down by British Government in 1926. The northern branch of Lower Jhelum Canal (constructed in 1904), provides better irrigation to the village. Most of the original population of Chak No.129 N.B. consisted of Military Pensioners who served the British Government and were allotted agricultural lands in this area as a reward.
