Our City. Our Say. Lisen, Connect and Collaborate.

A campaign powered by Healthy Cities for Adolescents – with young people, for healthier and more inclusive cities.

Why we started

Today, more than half of the world’s nearly four billion young people under the age of 30 live in urban areas. By 2030, 60% of all city dwellers will be under 18.

Young people are not just “the future.” They are today’s residents, with fresh ideas and lived experience of urban life. Yet, too often, their voices are left out.

Cities built with youth as equal partners are stronger, smarter, and more sustainable.

International Youth Day

In August 2025, adolescents across six HCA countries – Colombia, Ecuador, Ghana, Senegal, India, Vietnam – stepped in front of the camera to answer one powerful question. The result is a youth-produced film capturing diverse voices, ideas, and visions for healthier, more inclusive urban spaces.

We need to give young people the tools and space to contribute and shape the future they want, in the cities where they live!

Watch & share the film

Urban October

Urban October brought communities together to reflect on cities. Youth voices joined local authorities and community members to share real-world ideas and solutions for urban transformation.

On World Cities Day, we unveiled the Declaration Wall – a growing collection of commitments, visions, and solutions for healthier cities.

Explore the Declaration Wall

Let us listen, connect and collaborate with each other! Intergenerational dialogue is a necessary step for collaborative action towards healthier and more inclusive cities.

Looking ahead

This campaign is not over. The Declaration Wall is a living platform: a space where young people, educators, community leaders, and city officials will continue to contribute their voices and actions towards building healthier and more inclusive cities.
