Georges-Eugène Haussmann's modernization plan transformed many areas of Paris through the addition of wider boulevards, better lighting and water sanitation, new parks, and improved rail transportation.
Post-World War II suburban growth in the United States led to urban sprawl due to a combination of economic prosperity, federal policy, and shifting lifestyle preferences.
- Economic and Federal Support: Following the war, new federal loan programs and the GI Bill made homeownership significantly more affordable, allowing many citizens to purchase single-family homes. The Federal Housing Administration facilitated this by insuring long-term, low-down-payment mortgages, which favored new construction over existing urban housing.12
- Infrastructure: The development of the Interstate Highway System and other road-building projects made previously inaccessible land viable for development, enabling residents to live further from urban centers while remaining connected via automobiles.1
- Planning and Zoning: Many municipalities adopted single-use zoning, which separated residential areas from commercial and employment hubs. This design discouraged walkable communities and necessitated automobile reliance.31
- Lifestyle Choices: Many Americans moved to the suburbs to escape urban congestion and crime, or to pursue the "American Dream" of larger homes with private yards and modern amenities.341
