World Cities Day

World Cities Day is celebrated around the world on October 31st. The purpose of the holiday is to inform the population about global urbanization and unite for the sustainable development of cities. Various institutions, activists, movements reveal inequality in the largest metropolitan areas and promote social inclusion.


The holiday was founded by the United Nations in 2013. Since then, not a single year has passed that certain problems have not been solved. There is a lot of work, there is a need for volunteer help.

Following historical data, the first cities appeared in Mesopotamia. This happened around 7500 BC. Examples include Ur, Uruk, Eridu. They didn’t just appear anywhere – it was important to find more fertile soil to cultivate. Time passed, Mesopotamia turned into ruins, but other cities were founded all over our planet.

The UN gives interesting forecasts for 2030: according to their information, there will be 41 megacities with a population of about 10 million people. Most likely, the number of cities will increase in India, Congo. Time will tell how it actually happens. Another thing is important – people’s understanding of existence in cities.
