Health and Survival (0 to 1, where 1 indicates no gap). This subindex provides an overview of the differences between women’s and men’s health through the use of two indicators. The first is the sex ratio at birth, which aims specifically to capture the phenomenon of “missing women”, prevalent in many countries with a strong son preference. Second, we use the gap between women’s and men’s healthy life expectancy. This measure provides an estimate of the number of years that women and men can expect to live in good health by taking into account the years lost to violence, disease, malnutrition and other relevant factors.
