What the numbers say
In 2025, South Sudan's population in largest city rose 4.3% on 2024 (from 479,359 to 500,088).
Across the 30 yearly changes before that (1995 to 2024), the average change was +4.7% and a typical year strayed about 0.1% from that (the standard deviation). This year's change was 3.1 standard deviations below that average, so it was unusually large compared with the rest of the record.
On record, the biggest yearly rise was 10.2% in 1968. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2016 to 2025 the straight-line trend is upward, about 18,163 a year. A straight line explains 100% of the movement over 10 observed years.
Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.
A straight-line projection, tested first
Extending that straight line gives about 547,275 for 2028. We show this only because the same method, fitted on earlier years, predicted 2023 to 2025 better than "no change" would have: its average miss was 11,800, against 39,603 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

What this measures
Population in largest city is the urban population living in the country's largest metropolitan area.
Limitations: Aggregation of urban and rural population may not add up to total population because of different country coverage. There is no consistent and universally accepted standard for distinguishing urban from rural areas, in part because of the wide variety of situations across countries. Most countries use an urban classification related to the size or characteristics of settlements. Some define urban areas based on the presence of certain infrastructure and services. And other countries designate urban areas based on administrative arrangements.
