Every year, World Population Day is observed on 11 July to spread awareness about global population issues.

History of World Population Day

The day was first celebrated by the United Nations in 1989. It was inspired by ‘Five Billion Day’ on 11 July 1987, when the world population reached 5 billion.

A World Bank demographer, Dr. KC Zachariah, first suggested the idea for World Population Day after this milestone.
