After decades of struggle against Sudanese leadership based in Khartoum, the South Sudanese voted for independence from Sudan in 2011.
Two years later, following ethnically-motivated violence, South Sudan, the world's newest country, descended into a civil war.
2.5 million refugees have fled to neighbouring countries.
It is estimated that more than 383,000 people have died in the conflict.
As many journalists are denied access to or even barred from reporting within the country, we used a mobile phone survey to gather information.
We worked with South Sudan land rights experts and statisticians to design a survey that could quantify the scale of the conflict.
We dialled more than 35,000 random phone numbers on one of the country’s largest mobile phone networks in order to paint an accurate picture of displacement across the entire country.
We prerecorded 14 questions in six of the country’s major languages: Arabic, English, Dinka, Nuer, Bari and Madi.
Over 2,900 people listened to the survey and 405 people answered all 14 questions.
