World Population Day

World Population Day is celebrated to raise awareness about population issues, promote reproductive health and family planning, address sustainable development, advocate for gender equality, and inspire action towards finding solutions to global population challenges.

July 11th is observed as World Population Day because it commemorates the Day of Five Billion, which was observed on July 11, 1987. The Day of Five Billion marked the estimated global population reaching five billion people. The significance of this milestone generated interest and led to the establishment of World Population Day by the United Nations Development Programme (UNDP) in 1989.

World Population Day is an annual event observed on July 11 to raise awareness of population issues and the importance of family planning. It was established by the United Nations Development Programme (UNDP) in 1989, the year the world's population reached 5 billion.

World Population Day was suggested by Dr. K.C. Zachariah, a Senior Demographer at the World Bank, to commemorate the milestone of the global population reaching five billion. Dr. Zachariah played a significant role in advocating for the establishment of World Population Day while he worked at the World Bank.
