World Population Day
- World Population day is an annual event, observed on July 11 every year, which seeks to raise awareness of global population issues.
- The event was established by the Governing Council of the United Nations Development Programmein 1989. It was inspired by the public interest in Five Billion Day on July 11, 1987, the approximate date on which the world’s population reached five billion people.
- World Population Day aims to increase people’s awareness on various population issues such as the importance of family planning, gender equality, poverty, maternal health and human rights.
- The day was suggested by Dr KC Zachariah in which population reaches Five Billion when he worked as Sr Demographer at World Bank.
- While press interest and general awareness in the global population surges only at the increments of whole billions of people, the world population increases by 100 million approximately every 14 months. The world population reached 7,400,000,000 on February 6, 2016; the world population had reached 7,500,000,000 at around 16:21 on April 24, 2017.
- The theme of 2018 is “Family Planning is a Human Right”.
