It is estimated that South Sudan has a population of 8 million, subdivided into many tribes having their own culture and language.
More than 50% of the population is less than 18 years old.The decades of two civil wars have left more than 2.5 million people killed, and about more than 5 million externally or internally displaced.
According to U.N. estimates, only 55% of the population has access to drinking water. Less than 1/5 South Sudanese know how to read and write.Hundreds of thousands live in shacks, without access to medical infrastructure, decent sanitation facilities and schooling. Due to inadequate hygiene and a lack of potable water, infectious diseases spread easily. Roughly 80% of the country's population live in rural areas and depend on crop farming as their primary source of livelihood. Climate variation and natural disasters such as drought and flooding have a strong impact on their living conditions.
More than 90% of the population of South Sudan live on less than $1/day, making it one of the poorest countries in the world.
