Final answer:
In 2018, 55 percent of the world's population lived in urban areas. By 2050, 68 percent of the world's population is projected to be urban.
Step-by-step explanation:
In 2018, 55 percent of the world's population resided in urban areas. By 2050, it is projected that 68 percent of the world's population will be urban.
Urbanization rates vary across different regions. Currently, North America is the most urbanized region with 82 percent of its population living in urban areas, followed by Latin America/the Caribbean (81 percent) and Europe (74 percent). Africa is currently only 40 percent urbanized.
These projections indicate the global trend towards increased urbanization and highlight the importance of sustainable development in cities around the world.
