Least developed countries: UN classification: Adjusted net national income (constant 2015 US$)

Key figures

What the numbers say

In 2021, Least developed countries: UN classification's adjusted net national income (constant 2015 US$) rose 2.9% on 2020 (from US$1.08 trillion to US$1.12 trillion).

Across the 18 yearly changes before that (2003 to 2020), the average change was +5.7% and a typical year strayed about 2.1% from that (the standard deviation). This year's change was 1.4 standard deviations below that average, so it was larger than a typical year, though not out of the range seen before.

On record, the biggest yearly rise was 8.9% in 2006. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2012 to 2021 the straight-line trend is upward, about US$46.94 billion a year. A straight line explains 98% 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$1.25 trillion for 2024. We show this only because the same method, fitted on earlier years, predicted 2019 to 2021 better than "no change" would have: its average miss was US$57.16 billion, against US$117.85 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

Adjusted net national income is GNI minus consumption of fixed capital and natural resources depletion. 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.

Limitations: Adjusted net national income differs from the adjustments made in the calculation of adjusted net savings, by not accounting for investments in human capital or the damages from pollution. Thus, adjusted net national income remains within the boundaries of the United Nations System of National Accounts (SNA). The SNA includes non-produced natural assets (such as land, mineral resources, and forests) within the asset boundary when they are under the effective control of institutional units. The calculation of adjusted net national income, which accounts for net forest, energy, and mineral depletion, as well as consumption of fixed capital, thus remains within the SNA boundaries.

Regional and income-group figures are computed by the World Bank as a gap-filled total.
