Signal UN projects that more than 68 percent of the world's population will live in cities by 2050

Summary

The mobility overview cites a 2018 UN report projecting that over 68 percent of humanity will live in urban areas by 2050. The survey uses this outlook to explain why innovation in movement and transport has become central to city life. Concentration of people in cities is accelerating changes in mobility in both urban and rural areas and altering how cities look and function. In response, cities are testing layered use of underground, ground-level and airspace networks to use scarce land more efficiently. The projection underpins the expectation that autonomous vehicles and urban air mobility will reshape large cities over the coming decades.
