Every year since 1990, 11 July has been observed as World Population Day around the world. The day seeks to focus the attention of global stakeholders on the issues of population growth, their relations to the environment and development and related issues.
The 2024 World Population Day theme is “To Leave No One Behind, Count Everyone”.
This year's theme highlights the importance of collecting, analysing, and using population data to deliver health care globally.
The proper documentation of population data has led to substantial improvements in sexual and reproductive health and the community's ability to exercise rights and choices.
However, according to the United Nations, there are many marginalised communities in the world whose population data are yet not captured, adversely affecting their lives and well-being.
According to the United Nations, the global human population crossed the billion milestone in 1804, and it took another 126 years to reach the 2 billion population mark in 1930.
Following are the world’s most populous countries of now in descending order.
