Every year, World Population Day is observed on July 11, to highlight the problems of overpopulation and raise awareness about the effects of overpopulation on the environment and development.
Every year there is a specific theme for World Population Day and the theme of World Population Day 2022 is “A world of 8 billion: Towards a resilient future for all – Harnessing opportunities and ensuring rights and choices for all.”
It took hundreds of thousands of years for the world population to grow to 1 billion, then in just another 200 years or so, it grew sevenfold. In 2011, the global population reached the 7 billion mark, it stands at almost 7.9 billion in 2021, and it’s expected to grow to around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100.
World Population Day was established by the Governing Council of the United Nations Development Programme in 1989. It was inspired by the public interest in Five Billion Day, the approximate date on which the world’s population reached five billion people on July 11, 1987.
