World Population Day 2026: Discoveries from Discover

On 11 July, the global community marked World Population Day. This year's theme is “Realizing the hopes and aspirations of young people - today and for the future”. Young people play a critical role in shaping societies, driving innovation, and advancing sustainable development. This year's theme highlights the importance of understanding the opportunities and challenges that influence their decisions, well-being and future aspirations. 

To mark the occasion, we are showcasing a selection of recent research published in Discover series that explores both population dynamics and the experiences, well-being and aspirations of young people around the world.
