The principal official statistical agency for Southern Sudan was first established way back in 1995 when it functioned as a Database and Monitoring Unit under the Sudan Relief and Rehabilitation Association (SRRA). Over time, the unit evolved and was renamed the New Sudan Centre for Statistics and Evaluation (NSCSE) in 2003 under the then SPLM/SPLA administration in the then SPLM-controlled areas of Southern Sudan. The Centre was established with a mandate to develop the necessary capacity to become the professional source and effective provider of official statistical information for the SPLM-controlled areas. This was in response to the urgent need for basic statistical data in order to support decision-making and enable programme and policy monitoring in the South.
Later, under the Southern Sudan Interim Constitution in 2005, its name was changed to the Southern Sudan Centre for Census, Statistics and Evaluation (SSCCSE) and assigned specific mandates.
Today, the NBS is an autonomous statistics bureau of the Government of South Sudan (GoSS), and is responsible for collecting, coordinating, analyzing and disseminating all official statistical information on economic, social, demographic, environmental and general activities and conditions of the people of South Sudan. The NBS is also responsible for conducting all official censuses and surveys in South Sudan, monitor and evaluate social impacts of public policies, projects, programmes and monitor the progress of poverty alleviation and the attainment of the Millennium Development Goals.
