Papua New Guinea: GDP, PPP (constant 2021 international $)

Key figures

What the numbers say

In 2025, Papua New Guinea's GDP, PPP (constant 2021 international $) rose 5.6% on 2024 (from 45.4 billion to 47.96 billion).

Across the 30 yearly changes before that (1995 to 2024), the average change was +3% and a typical year strayed about 4.3% from that (the standard deviation). This year's change was 0.6 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 18.2% in 1993 and the biggest yearly fall was 3.9% in 1997. 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 906.49 million a year. A straight line explains 81% 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 49.12 billion 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 750.22 million, against 3.59 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

This indicator provides values for gross domestic product (GDP) expressed in constant international dollars, converted by purchasing power parities (PPPs). PPPs account for the different price levels across countries and thus PPP-based comparisons of economic output are more appropriate for comparing the output of economies and the average material well-being of their inhabitants than exchange-rate based comparisons. Gross domestic product is the total income earned through the production of goods and services in an economic territory during an accounting period. It can be measured in three different ways: using either the expenditure approach, the income approach, or the production approach. 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 2021. The PPP conversion factor is a currency conversion factor and a spatial price deflator. PPPs convert different currencies to a common currency and, in the process of conversion, equalize their purchasing power by eliminating the differences in price levels between countries, thereby allowing volume or output comparisons of GDP and its expenditure components.

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