What the numbers say
In 2025, Least developed countries: UN classification's gross national expenditure (constant 2015 US$) rose 4.3% on 2024 (from US$1.55 trillion to US$1.62 trillion).
Across the 23 yearly changes before that (2002 to 2024), the average change was +5.1% and a typical year strayed about 1.7% from that (the standard deviation). This year's change was 0.5 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 7.4% in 2007. 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 US$60.64 billion a year. A straight line explains 99% 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 US$1.76 trillion 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 US$63.21 billion, against US$112.91 billion 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
Gross national expenditure is the sum of household final consumption expenditure, general government final consumption expenditure, and gross capital formation. This indicator is expressed in constant prices, meaning the series has been adjusted to account for price changes over time. The reference year for this adjustment is 2015. This indicator is expressed in United States dollars.
Regional and income-group figures are computed by the World Bank as a gap-filled total.
