By 2026, South Sudan is projected to be home to 12,436,037 people. That is a 5-fold increase on the 2,493,283 recorded in 1950. It is growing at +2.02% a year, one of the faster rates globally, adding about 250.8K people a year. With only 22 people/km², it is one of the world's more sparsely settled countries. Half the population is younger than 19.0 years, and the age structure is steadily tilting older: the median is projected to reach 25.0 by 2050. The sexes are close to evenly balanced, at 97 males per 100 females. By 2100, UN projections see it rising to 23,840,772, up 92% from 2026.
