World Population Day is an annual event, observed on 11 July every year, aiming to raise awareness of global population issues. The event 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 on 11 July 1987, the approximate date on which the world’s population reached five billion people. World Population Day aims to increase people’s awareness on various population issues such as the importance of family planning, gender equality, poverty, maternal health, and human rights.

The theme of World Population Day 2025 is “Empowering young people to create the families they want in a fair and hopeful world”. Global fertility rates are falling, prompting warnings about “population collapse”. But the United Nations Population Fund (UNFPA)’s State of World Population report shows that the real issue is a lack of reproductive agency—many people, especially young people, are unable to have the children they want. World Population Day 2025 highlights this challenge, focusing on the largest-ever generation of young people.

In celebration of this day, we invite you to explore a curation of insightful articles, journals, and Special Issues across various fields, including sociology, economics, human resources, and humanities. By sharing these findings, we call for ensuring that young have the rights, tools, and opportunities to shape their futures.
