Citiesabc was created by a team of global industry leaders, academics and experts to create new solutions, resources, rankings and connections for the world’s top cities and populations.

We believe that every city needs to become a live digital platform, where ideas, resources, tech, data, intelligence can be recorded, accessed and shared.

Our organisation enables and helps with the coordination of knowledge and resources, enabling cities to understand how to optimise, unite and support the fast-growing and shifting dynamics of cities around the world, and enable different citizen groups to find new narratives, stories and solutions to meet their particular problems, struggles, opportunities and needs.

citiesabc demonstrates how the fast-growing cities around the world enable their citizens to meet particular needs. With over half of the planet now living in cities, and more than two-thirds of the world’s population will be urbanised by 2050, cities are at the epicentre of humanity and social models. They contribute to four-fifths of the global GDP, and are taking centre stage in securing an inclusive, safe, productive, sustainable, and resilient future for humanity.
