Jonglei State: population, health, nutrition, schooling, water and child protection

Jonglei State is a state of South Sudan, the largest of 10 by population. The National Bureau of Statistics projects the population of Jonglei State at 2,491,577 for 2026 (1,283,684 male, 1,207,893 female), 15.2% of South Sudan's projected 16.37 million; the largest of the 10 states. The projection was published in 2016 from the 2008 census, the last one held, so it does not reflect the conflict and displacement since then.
