Some appalling statistics, among the worst in the world.
"More than 90% of the population of South Sudan live on less than $1 a day, despite the GDP per capita of the entirety of Sudan being $1200.Humanitarian services are administered by NGOs.[ Yet the land looks good grasslands and is rich in minerals. Whereas the north has the very dry Nubian Desert. "An expanding desert is a serious problem. Nearer the River Nile, there are well-irrigated farms growing cash crops." ]
"The under-five infant mortality rate is 112 per 1,000, whilst maternal mortality is the highest in the world at 2,053.9 per 100,000 live births. [ death rate is high, but birth rate is higher.]

AP Thur March 17, 2011. [today, as I write this] Norway paid for a first printing press in Southern Sudan, 'The Citizen,' a daily Southern Sudanese newspaper. As the editor was giving a tour of the new press to his sponcers and as he was criticizing the government's repressive media politics, two dozen plainclothes agents armed with AK-47s arrived and told the diplomats to leave, took the newsman in custody, drive him around for two hours before releasing him.
