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.

Background to the World Population Day

  • The date 11 July was chosen as on this date in 1987; the global population was officially declared to have crossed the five billion mark.
  • The first Population Day was observed on 11 July 1990.
  • Later, the United Nations General Assembly passed a resolution in December 1990 to declare 11 July as World Population Day.

Theme of the 2024 World Population Day 

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.

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.

  • In 2011, the world's human population crossed 7 billion. 
  • On 15 November 2022, the global human population crossed 8 billion.
  • The United Nations expect the human population to reach around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100.
