Answer:
World populations are increasingly moving from rural to urban centers, making for larger cities with greater population density than ever before. This is a global phenomenon across the spectrum of developed and developing economies. We are increasingly becoming an urban world.
The rates of change and specific migration patterns differ in various parts of the globe. The developing world congregates more in mega-cities, while Americans are increasingly moving to both downtowns and the urban sprawl around dominant business and industry-specific hubs. There are many questions about what this growth means, how prepared cities are, and if and when it will end. However, the world has clearly been urbanizing for some time, and experts from major development organizations project this trend to continue into the foreseeable future.
The data is eye-opening. The United Nations in 2009 and the International Organization for Migration in 2015 both estimated that around 3 million people are moving to cities every week. Approximately 54% of people worldwide now live in cities, up from 30% in 1950. Sources estimate this will grow to 2/3 of world population in the next 15-30 years. More than half of urban dwellers live in the 1,022 cities with greater than 500,000 inhabitants. There are currently 29 megacities with populations of over 10 million, up from 2 in 1950 and projected to grow to between 41 and 53 by 2030. Additionally, there are 468 cities with a population of over 1 million, up from 83 in 1950. A Yale research group projects that urban land coverage will expand by 463,000 square miles by 2030 to cover just under 10% of the planet’s land, equivalent to 20,000 football fields being paved over every day.
