One of our great urbanists and one of our great public health experts join forces to reckon with how cities are changing in the face of existential threats the pandemic has only accelerated
 

Cities can make us sick. They always have—diseases spread more easily when more people are close to one another. And disease is hardly the only ill that accompanies urban density. Cities have been demonized as breeding grounds for vice and crime from Sodom and Gomorrah on. But cities have flourished nonetheless because they are humanity’s greatest invention, indispensable engines for creativity, innovation, wealth, and connection, the loom on which the fabric of civilization is woven.
 
But cities now stand at a crossroads. During the global COVID crisis, cities grew silent as people worked from home—if they could work at all. The normal forms of socializing ground to a halt. How permanent are these changes? Advances in digital technology mean that many people can opt out of city life as never before. Will they? Are we on the brink of a post-urban world?
 
City life will survive but individual cities face terrible risks, argue Edward Glaeser and David Cutler, and a wave of urban failure would be absolutely disastrous. In terms of intimacy and inspiration, nothing can replace what cities offer. Great cities have always demanded great management, and our current crisis has exposed fearful gaps in our capacity for good governance. It is possible to drive a city into the ground, pandemic or not. Glaeser and Cutler examine the evolution that is already happening, and describe the possible futures that lie before us: What will distinguish the cities that will flourish from the ones that won’t? In America, they argue, deep inequities in health care and education are a particular blight on the future of our cities; solving them will be the difference between our collective good health and a downward spiral to a much darker place.

America is an urban nation. More than two thirds of us live on the three percent of land that contains our cities. Yet cities get a bad rap: they’re dirty, poor, unhealthy, crime ridden, expensive, environmentally unfriendly. Or are they?
As Edward Glaeser proves in this myth-shattering book, cities are actually the healthiest, greenest, and richest (in cultural and economic terms) places to live. New Yorkers, for instance, live longer than other Americans; heart disease and cancer rates are lower in Gotham than in the nation as a whole. More than half of America’s income is earned in twenty-two metropolitan areas. And city dwellers use, on average, 40 percent less energy than suburbanites.
Glaeser travels through history and around the globe to reveal the hidden workings of cities and how they bring out the best in humankind. Even the worst cities-Kinshasa, Kolkata, Lagos-confer surprising benefits on the people who flock to them, including better health and more jobs than the rural areas that surround them. Glaeser visits Bangalore and Silicon Valley, whose strangely similar histories prove how essential education is to urban success and how new technology actually encourages people to gather together physically. He discovers why Detroit is dying while other old industrial cities-Chicago, Boston, New York-thrive. He investigates why a new house costs 350 percent more in Los Angeles than in Houston, even though building costs are only 25 percent higher in Los Angeles. He pinpoints the single factor that most influences urban growth-January temperatures-and explains how certain chilly cities manage to defy that link. He explains how West Coast environmentalists have harmed the environment, and how struggling cities from Youngstown to New Orleans can “shrink to greatness.” And he exposes the dangerous anti-urban political bias that is harming both cities and the entire country.
Using intrepid reportage, keen analysis, and eloquent argument, Glaeser makes an impassioned case for the city’s import and splendor. He reminds us forcefully why we should nurture our cities or suffer consequences that will hurt us all, no matter where we live.
