The Day of Seven Billion, October 31, 2011, is the day that was officially designated by the United Nations Population Fund (UNFPA) as the approximate day on which the world's population reached seven billion people.^[2] United Nations Secretary General Ban Ki-moon spoke at the United Nations building in New York City on this new milestone in the size of world population and the issues that it will raise, along with promoting the UNFPA's new program named 7 Billion Actions,^[3] which will seek to "build global awareness around the opportunities and challenges associated with a world of seven billion people" and inspire individuals and organizations to take action.^[4] It was succeeded by the Day of Eight Billion on November 15, 2022.
