About Gender Inequality Index
UNDP’s Gender Inequality Index measures the human development a country loses to the gap between women and men, across reproductive health, empowerment and the labour market. It runs from 0, full equality, to 1, maximum inequality — so here, lower is better.
What the number is: GII (0 = full equality, 1 = maximum inequality).
What it does not measure
It covers reproductive health, representation and labour-market participation only; unpaid care work, violence against women and pay gaps are outside it.

How this page reads the numbers
- The rank is UNDP Human Development Report Office’s own, as published.
- 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.
