The United Nations General Assembly designated every 31st October as World Cities Day (WCD).
The global observation of World Cities Day 2019 will be hosted by Ekaterinburg, in the Russian Federation. The theme is “Changing the world: innovations and better life for future generations”.
World Cities Day promotes sustainable, inclusive urbanization around the world and engenders international cooperation to address the challenges of urbanization. Urbanization is happening at a phenomenal rate. Half the world's population now live in cities, and this is projected to increase to two-thirds by 2050.
UN-Habitat leads the observation and promotion of World Cities Day in collaboration with partners from the United Nations system, international organizations, civil society and business leaders.
The general theme of World Cities Day is 'Better City, Better Life', and each year a different sub-theme is selected, to either promote successes of urbanization, or address specific challenges resulting from urbanization.
Last year the host city for World Cities Day was Liverpool, UK and there were 50 activities in 23 countries to celebrate the day.
