Melinda Gates will celebrate World Population Day by avoiding saying the word “population,” and at the same time doing more to address population-related challenges than anyone else on the planet.

She has adopted family planning as her signature issue and is leading an effort by the Bill and Melinda Gates Foundation to make contraceptives widely available to women in developing countries. On July 11, World Population Day, she’ll be headlining the London Summit on Family Planning, cosponsored by her foundation and the U.K. government. The aim of the summit is to raise $4 billion to provide family-planning services over the next eight years to 120 million women. About twice that many women now lack access, which Gates says is “a crime.”
