World Population Day is celebrated annually on July 11th to raise awareness of global population issues and sustainable development. It was established in 1989 by the UNDP Governing Council. The day commemorates when the world population reached 5 billion in 1987. It aims to spread knowledge about reproductive health and rights through various events organized by participating UN nations and organizations. This year's theme focuses on women's and girls' sexual/reproductive health vulnerabilities during the COVID-19 pandemic.
