Samoa: Adjusted net national income (constant 2015 US$)

Key figures

What the numbers say

In 2021, Samoa's adjusted net national income (constant 2015 US$) fell 4.1% on 2020 (from US$807.31 million to US$773.81 million).

Across the 11 yearly changes before that (2010 to 2020), the average change was +3.3% and a typical year strayed about 15.7% 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 31.5% in 2013 and the biggest yearly fall was 21.9% in 2014. 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 there is no clear straight-line trend: a straight line explains 23% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

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.
