The report’s Gender Gap Index ranks countries according to their gender gaps, and their scores can be interpreted as the percentage of the equality between women and men that has been closed. Information about gender imbalances to the advantage of women is explicitly prevented from affecting the score.[1] So, for example, the indicator "number of years of a female head of state (last 50 years) over male value" would score 1 if the number of years was 25, but would still score 1 if the number of years was 50.
