The spread
188 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 69.303; a quarter are above 83.674, and a quarter below 58.218. The bar in each row marks that continent’s middle country.
04All 188 ever measured
Every country
In order, highest value first. “=” marks a position shared with another country. World Bank Group ranks nobody on this measure; the position is derived here by ordering the published values. The five pillars behind the score are stored alongside it, and they often disagree — a country can publish plenty of data and still publish it badly.

Each point is one reference year from 2016. A country with a weak statistical system is a country whose other figures are shakier, and this is the line where that shows.

187 countries were measured in both 2023 and 2024. The field changed from 187 to 188 countries, so a place can move for reasons that have nothing to do with the country itself.

About statistical performance
The Statistical Performance Indicators score how well a country’s own statistical system works, out of 100, across data use, services, products, sources and infrastructure. It is the only measure here whose subject is the production of data itself — which makes it a useful caution to read beside every other number on this site.
What the number is: SPI overall score (0–100).
What it does not measure
It scores the statistical system itself, not the quality of any single published figure, and not whether governments act on what their statistics show.
09Where it fits

11Questions
Statistical performance: questions and answers
Which country has the highest statistical performance?
Norway, at 94.143, among the 188 countries compared in 2024.
Which country has the lowest statistical performance?
South Sudan, at 27.123, among the 188 countries compared in 2024.
How many countries does the Statistical Performance Indicators cover?
188 in 2024. The number measured varies from 167 to 188 between editions.
What is the world average statistical performance?
This site does not calculate a world average, which would depend on how countries are weighted. In the middle country of the 188 compared in 2024, the figure was 69.303.
Is this World Bank Group’s own ranking?
No. World Bank Group publishes the values but ranks nobody; the position on this page is derived by Nations Inquiry by ordering the published values, and equal values share a position.
How often is the Statistical Performance Indicators published?
This site holds 9 reference years, 2016–2024, all recalculated in World Bank Group’s 2026 report on one method — not 9 separate publications.
Where does the data come from, and can I download it?
From World Bank Group, under CC BY 4.0. Pulled from the World Bank’s indicator API (IQ.SPI.OVRL). The SPI was introduced in 2021 and back-computed to 2016, and each release recalculates the whole panel rather than adding an edition. Every edition is available on this site’s Datasets pages as a full table, unrounded.

How this page reads the numbers
- World Bank Group ranks nobody on this measure. The position is derived by Nations Inquiry by ordering the published values; equal values share a position.
- Which end is better follows the publisher’s own reading of the measure.
- A country is named at an end only when it holds that value alone. Where several share it, the page says how many and names none first.
- Values are stored exactly as published and trimmed only for display. “The middle country” is the median of the countries measured, not a world average.
The full note on this data
9 reference years (2016–2024), growing from 167 to 188 countries, pulled from the World Bank's indicator API (IQ.SPI.OVRL). The SPI scores how well a country's own statistical system works, across five pillars — data use, data services, data products, data sources and data infrastructure. It is the only measure here whose subject is the production of data itself, which makes it a useful caution to read beside every other indicator on the site: a country with a weak statistical system is a country whose other numbers are shakier. ⚠ These are not 9 separately published reports. The SPI was introduced in 2021 and back-computed to 2016, and each release recalculates the whole panel — `restatedByReport` names the World Development Indicators release this was pulled from (August 2026), not a printed annual report. ⚠ A statistic, not an index: no rank is published, so none is stored; the POSITION shown on the statistics page is derived here by ordering the score, and labelled as ours.
