By 2050, nearly 7 out of 10 people in the world will live in cities, up from just over half in 2020. Urbanization is nothing new, but an effort is under way across many high-income countries to make their cities smarter, using data, instrumentation and more efficient resource management. In most of these nations, the vast majority of smart-city projects involve upgrades to existing infrastructure. Japan stands out for its willingness to build smart communities from scratch as it grapples with a rapidly ageing population and a shrinking workforce, meaning that there are fewer people of working age to support older people.
