Khan Sen Sok was established in 2008–2009 by taking three Sangkats—Khmuonh, Phnom Penh Thmei and Tuek Thla—from Khan Russey Keo.[2] The population recorded in the resulting area by the 2008 census was 120,579.[3]
In 2010 Ponhea Pon, Prek Pnov and Samraong communes were added to the Khan from Ponhea Lueu District, Kandal Province.[4] In 2013, the latter three Sangkats formed a part of a new entity, Khan Prek Pnov, while Sangkat Krang Thnong, previously belonging to Khan Pou Senchey, was added to Sen Sok.[5] In 2016, two new Sangkats were established by separating areas from existing subdivisions—Ou Baek K'am from Tuek Thla and Kouk Khleang from Phnom Penh Thmei.[5]
As of 2020, Sen Sok is subdivided into six Sangkats (communes) and 47 Phums (villages).[5]
