World: Prosperity gap (average shortfall from a prosperity standard of $28/day)

Key figures

Since 1981 it is down 63.78% from 12.7 in 1981 (2.33% a year on average, compounded). The World Bank has no value for 1 of the years in between; the chart leaves those gaps open rather than joining across them.

What the numbers say

In 2024, World's prosperity gap (average shortfall from a prosperity standard of $28/day) fell 2.1% on 2023 (from 4.7 to 4.6).

Across the 30 yearly changes before that (1992 to 2023), the average change was −2.7% and a typical year strayed about 1.5% from that (the standard deviation). This year's change was 0.4 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 4% in 1989 and the biggest yearly fall was 5.5% 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 2015 to 2024 the straight-line trend is downward, about 0.06 a year. A straight line explains 87% of the movement over 9 observed years.
