Because per capita incomes are higher in cities than in rural areas, the world’s cities today are estimated to account for more than 80% of global income, with the largest 600 accounting for around half. Most of the new jobs over the next few decades will be created in cities, offering livelihoods to hundreds of millions of young people and, as China and Brazil have demonstrated, helping to slash extreme poverty.
城市的人均收入高于农村，因此预计如今世界城市占据着全球收入的80%以上，其中最大的600个城市就占据了一半。未来几十年中新增就业岗位大部分也将出现在城市，为数亿年轻人提供安身立命之本，在中国和巴西等国家更能有助于减少极端贫困。
