The population was 12,935 in 2016. The mukim is home to some of the country's museums and historical sites, in particular in Kota Batu. The mukim could be named after a village that it encompasses, Kampong Kota Batu. The name Sungai Bunga translates to. According to legend, the river occasionally smells like jasmine flowers. Particularly at night, the stench is strongest. But, if one attempted to look for the smell's source, they would never succeed. The small invisible people who live in the river, known locally as Orang Kebenaran or Orang Bunian, are thought to be the source of the pleasant flower scent.
