World Cities Day brings Urban October to an end on 31 October each year and was first celebrated in 2014. As with World Habitat Day, a global observance is held in a different city each year and the day focuses on a specific theme. It aims to raise international awareness of urbanization trends, challenges, and visions for sustainable urban development, promote international cooperation, and contribute to global efforts to build equitable, prosperous, sustainable, and inclusive cities that provide their communities with better living environments and quality of life.

2025 Theme: People-Centred Smart Cities

On 31 October 2025, the Global Observance of World Cities Day will take place in Bogotá, Colombia, under the topic of people-centred smart cities. It will showcase how data-driven decision making, technology, and AI can be used to improve urban life and recover from current shocks and crises. It will also focus on promoting smart city initiatives centered on people.

This year's theme reflects the growing recognition that the transformative power of digital technologies is reshaping urban life globally, offering profound opportunities to enhance how cities and human settlements are designed, planned, managed and governed. In an era marked by both urban and digital transitions, cities are increasingly adopting digital technology solutions and data to deliver better services for residents and address critical urban challenges and opportunities.

The aim of this year's theme is to promote people-centred smart cities and demonstrate how crucial it is for smart cities to prioritize human needs, inclusivity, and accessibility. Second, the observance will provide a platform for cities to exchange best practices, experiences and strategies in implementing people-centred smart city initiatives globally, especially in addressing key challenges such as the global housing crisis. Lastly, by increasing global awareness about the role of technology and innovation in advancing improved access to adequate housing and achieving urban development, the goal is to foster and encourage international cooperation and collaboration among all societal sectors on People-Centred Smart Cities.

Biennial publication: World Cities Report 2024

UN-Habitat launched the 2024 edition of its World Cities Report at the World Urban Forum (WUF12), focusing on the urgent intersection of climate action and rapid urbanization.

This biennial publication serves as a global reference on sustainable urban knowledge, revealing critical findings.

With a vast funding gap of $4.5-5.4 trillion needed annually for resilient infrastructure, the report also highlights the risks of “green gentrification” that can displace vulnerable communities. It emphasizes the importance of community-led strategies to guide cities toward sustainable futures.

Background

The United Nations General Assembly designated 31 October as World Cities Day, by its resolution 68/239. The Day is expected to greatly promote the international community’s interest in global urbanization, push forward cooperation among countries in meeting opportunities addressing challenges of urbanization and contributing to sustainable urban development around the world.

Urbanization provides the potential for new forms of social inclusion, including greater equality, access to services and new opportunities, and engagement and mobilization that reflects the diversity of cities, countries and the globe. Yet too often this is not the shape of urban development. Inequality and exclusion abound, often at rates greater than the national average, at the expense of sustainable development that delivers for all.

Urban October was launched by UN-Habitat in 2014 to emphasize the world’s urban challenges and engage the international community towards the New Urban Agenda.

Sustainable Development Goal 11, which formulates the ambition to make cities and human settlements inclusive, safe, resilient and sustainable - underlying the relevance of UN-Habitat’s mission. Inequalities in cities have grown since 1980. The world largest cities are also often the most unequal, and this year’s theme is embraced by the action and implementation of the New Urban Agenda, which is putting the topic of inclusive cities as one of the main pillars for the urban shift.

In October 2016, the HABITAT III Conference, held in Quito, adopted a new framework, which will set the world on a course towards sustainable urban development by rethinking how cities are planned, managed and inhabited. The New Urban Agenda will set the pace on how to deal with the challenges of urbanization in the next two decades, and is seen as an extension of the 2030 Agenda for Sustainable Development, agreed on by the 193 Member States of the UN in September 2015.

Cities should be encouraged to innovate and experiment, and also to learn from one another in order to hasten this transition, for instance through “twin town” initiatives or city networks. Moreover, the report says it will be necessary to replace a “competitive cities” governance approach to urban economies with a “well-grounded cities” approach that serves the interests of all citizens.

Until 2009, more people lived in rural than in urban areas. Today, around 55 per cent of the world’s population lives in towns and cities, with the level of urbanisation projected to reach almost 70 per cent by 2050. Much of the growth in urban populations will take place in Asia and Africa, especially in China, India and Nigeria where the fertility rates remain high.

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 United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
