In recent months, a consortium of governmental and international bodies initiated the latest round of the multi-sector Food Security and Nutrition Monitoring System (FSNMS+) survey in South Sudan. The survey uses GRID3 population estimates to calculate population per enumeration area.

Enumeration for South Sudan’s Population Estimation Survey (PES) has been completed, marking the end of the single largest data collection effort in the country’s history.

On 21 May, field data collection began for South Sudan’s National Population Estimation Survey (PES), an important milestone in the country’s effort to collect baseline demographic and socioeconomic data.

GRID3 has updated its high-resolution gridded population estimates which provides timely population data for the Government of South Sudan and other decision-makers. GRID3 South Sudan technical experts produced the estimates by combining 2008 county level census data collected by the National Bureau of Statistics with field-collected displacement data from IOM (through its Displacement Tracking Matrix) and UNHCR, the UN Refugee Agency.
