A boma is a lowest-level administrative division, below payams, in South Sudan.
Equivalent fifth-level divisions elsewhere are described as village, block or ward.
[1] As of 2009, South Sudan's 514 payams have an average of 4.2 bomas each.
[2] Bomas vary in size and typically contain many individual villages.
[3] The term boma originated from the town of Boma in Jonglei, the first place captured by the Sudan People's Liberation Army at the start of its 1983 insurgency.
