03The whole field at once
The spread
140 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 25.2; a quarter are above 40.6, and a quarter below 16.8. The bar in each row marks that continent’s middle country.
04All 140 ever measured
Every country
In order, highest value first — position 1 is the highest value, the way OECD’s own tables read. “=” marks a position shared with another country. OECD ranks nobody on this measure; the position is derived here by ordering the published values. A higher score is worse, so position 1 is the MOST discriminatory country, not the least: the table opens on Mauritania at 67.4 and closes on Norway at 6.7. Its four dimensions are stored beside the headline.

07The measure
About Social Institutions and Gender Index
The OECD’s Social Institutions and Gender Index scores discrimination against women in law and custom, from 0 (none) to 100 (absolute). Its inputs are legal codes, inheritance rules, attitudes to violence and restrictions on movement — the causes, where the other gender measures here count the results.
What the number is: SIGI score (0 = no discrimination, 100 = absolute).
What it does not measure
It measures discrimination built into social institutions, not women's outcomes in health, schooling or income, which other statistics on this site cover.

A key statistic for Gender & Equality
“Discrimination in social institutions and norms. Correlates 0.850 with Women, Business and the Law, inside the 0.92 bar, and kept because law and custom diverge widely.”

Mauritania, at 67.4, among the 140 countries compared in 2023.
How many countries does the Social Institutions and Gender Index cover?

What is the world average Social Institutions and Gender Index?

Is this OECD’s own ranking?
No. OECD 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 Social Institutions and Gender Index published?
This site holds one edition, describing 2023.
Where does the data come from, and can I download it?
From OECD, under OECD Terms and Conditions — data clause. From the OECD Development Centre via its SDMX API. A different question from the Gender Inequality Index, Women Business and the Law and the Gender Development Index rather than a fourth answer to the same one. Every edition is on this site’s Datasets pages as a full table, and downloads as a CSV file with every value unrounded.

How this page reads the numbers
- OECD 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 file itself, column by column — where it came from, what each column holds, and every edition as a CSV — is on its dataset page.
