Samoa: Export unit value index (2015 = 100)

Key figures

What the numbers say

In 2025, Samoa's export unit value index (2015 = 100) rose 2.8 on 2024 (from 118.2 to 121).

Across the 30 yearly changes before that (1995 to 2024), the average change was +2.12 and a typical year strayed about 7.85 from that (the standard deviation). This year's change was 0.1 standard deviations above 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 23 in 2023 and the biggest yearly fall was 35.6 in 1990. 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 there is no clear straight-line trend: a straight line explains 18% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures

Export unit value indices come from UNCTAD's trade database. Unit value indices are based on data reported by countries that demonstrate consistency under UNCTAD quality controls, supplemented by UNCTAD’s estimates using the previous year’s trade values at the Standard International Trade Classification three-digit level as weights. To improve data coverage, especially for the latest periods, UNCTAD constructs a set of average prices indexes at the three-digit product classification of the Standard International Trade Classification revision 3 using UNCTAD’s Commodity Price Statistics, interna¬tional and national sources, and UNCTAD secretariat estimates. This indicator is an index series where 2015=100.
