SOUTH SUDAN: New internally displaced persons baseline

 Key messages

• South Sudan’s baseline on internally displaced persons (IDPs) was reset from 1,829,223 individuals reported in the July 2019 Humanitarian Snapshot to 1,465,542 individuals reported in the August 2019 Snapshot.

• The reduction of more than 360,000 individuals does not reflect the actual change in IDP numbers between July and August. The real net decrease in the IDP figure during the one-month period is 26,302 individuals.

• Instead, the drop in numbers represents the culmination of an 18-month-long review and rationalization exercise between IDP datasets maintained by the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) and the International Organization for Migration’s Displacement Tracking Matrix (DTM). The large-scale reduction in the IDP count is specifically caused by updating data through revisiting locations and obtaining new population estimates, and reviewing all data for potential duplications.

• Moving forward, OCHA and DTM will maintain a unified IDP baseline for South Sudan, updated after the release of every new DTM mobility tracking round, approximately four times a year.

• The 2020 Humanitarian Needs Overview for South Sudan will use the previous, 1.8 million IDP baseline, as the population groups for the needs analysis were established before the new baseline was set.
