Book excerpt: While federal action on immigration faces an uncertain future, states, cities and suburban municipalities craft their own responses to immigration. Twenty-First-Century Gateways, focuses on the fastest-growing immigrant populations in metropolitan areas with previously low levels of immigration—places such as Atlanta, Austin, Charlotte, Dallas-Fort Worth, Minneapolis-St. Paul, Phoenix, Portland, Sacramento, and Washington, D.C. These places are typical of the newest, largest immigrant gateways to America, characterized by post-WWII growth, recent burgeoning immigrant populations, and predominantly suburban settlement. More immigrants, both legal and undocumented, arrived in the United States during the 1990s than in any other decade on record.

The case examples by a group of leading multidisciplinary immigration scholars explore the challenges of integrating newcomers in the specific gateways, as well as their impact on suburban infrastructure such as housing, transportation, schools, health care, economic development, and public safety. The changes and trends dissected in this book present a critically important understanding of the reshaping of the United States today and the future impact of
