New Growth of Cities - NYTimes.com "Is Suburban Sprawl on Its Way Back?" (news analysis, Sunday Review, Sept. 15) questions whether suburban sprawl is on the resurgence. What I know as an urban mayor is that our cities are growing and flourishing, reversing a half-century trend. Census Bureau statistics reveal that the country's urban population grew by 12.1 percent from 2000 to 2010, outpacing the country's overall growth rate of 9.7 percent. Mayors across America are welcoming this new growth by championing restaurants, galleries and museums. They are making their cities safer, building parks and recreation facilities, and improving public schools so that families stay rather than head for the suburbs like their parents. The success of our cities also benefits our suburbs, as those communities adopt successful urban housing policies, like high-density dwellings near train stations and micro-city environments that mirror urban living. So perhaps the headline should have read, "As Our Cities Rise, So Do Our Suburbs."
