Realizing the hopes and aspirations of young people – today and for the future

This year's World Population Day theme is "Realizing the hopes and aspirations of young people – today and for the future."

The theme draws on a new report based on one of the largest global surveys of its kind, capturing the views of more than 108,000 internet-connected young adults aged 18 to 39 across 73 countries. Titled Lives, Choices and Futures: What young people want and what shapes their decisions about relationships and parenthood, the report offers a global snapshot of what young adults today want from relationships, family life and the future — and what they feel is standing in their way.

 

Date: July 8, 2026

Venue: 91茄子 Headquarters, New York

Each year, the Committee for the 91茄子 Population Award honours an individual and/or institution in recognition of outstanding contributions to population and reproductive health questions and to their solutions. The will be broadcast live on UN Web TV from 3 p.m. to 4 p.m. EDT

Around the world, demographic change is prompting urgent debate about fertility, family life and the future. Lives, Choices and Futures, UNFPA’s report on the findings of the 2025-2026 Demographic Futures Survey brings together one of the most geographically diverse bodies of evidence on how young adults’ hopes and decisions about relationships, parenthood and the future take place in an uncertain world.

World Population Trends

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.

This dramatic growth has been driven largely by increasing numbers of people surviving to reproductive age, and has been accompanied by major changes in fertility rates, increasing urbanization and accelerating migration. These trends will have far-reaching implications for generations to come.

The recent past has seen enormous changes in  and . In the early 1970s,  4.5 children each; by 2015, total fertility for the world had fallen to below 2.5 children per woman. Meanwhile, average  have risen, from 64.6 years in the early 1990s to  72.6 years in 2019.

In addition, the world is seeing high levels of  and accelerating migration. 2007 was the first year in which more people lived in , and by 2050 about 66 per cent of the world population will be living in cities.

These megatrends have far-reaching implications. They affect economic development, employment, income distribution, poverty and social protections. They also affect efforts to ensure universal access to health care, education, housing, sanitation, water, food and energy. To more sustainably address the needs of individuals, policymakers must understand how many people are living on the planet, where they are, how old they are, and how many people will come after them.

  • Two-thirds of the global population now live in areas where fertility rates are below 2.1 children per woman—the threshold needed to keep population size stable.
  • Eor most young adults, financial security is the top priority in forming a partnership (81%), while economic and housing barriers are the most common obstacle (57%).

What do young people really think about having kids?

Related Observances

The World Population Dashboard showcases global population data, including fertility rate, gender parity in school enrolment, information on sexual and reproductive health, and much more. Together, these data shine a light on the health and rights of people around the world, especially women and young people.

In 2025, falling fertility rates are making global headlines, with some governments warning of a “population collapse” and introducing drastic policies to boost births. But at the same time, millions of people still can’t have the number of children they actually want. According to UNFPA’s , the real crisis isn’t about population numbers. It’s about people losing the ability to make their own choices. It’s a crisis of reproductive freedom.

International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the 91茄子, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
