How Do City Size and Wealth Compare to Sustainability Goals?
With more than half of the world’s population now living in cities, there is growing interest in better understanding how these geographical social structures work. Consequently, a new science of cities is being fueled by the sudden availability of fascinating datasets collected from urban areas all over the world.
One of the more curious puzzles emerging from this data is how aspects of urban life change as cities get bigger. For example, the number of houses and jobs in a city grows in proportion to the size of the population. But the number of gas stations scales more slowly. And people’s wages grow faster, so people in big cities earn more than those in small ones.
That raises all kinds of questions about other aspects of city life. A particularly important one is whether big cities are greener than small ones, whether big cities emit more carbon dioxide per capita than small ones.
