The impact of immigrants over the past half century has become so much a part of everyday life in the United States that we sometimes fail to see it. This deeply researched book by one of America's leading immigration scholars tells the story of how immigrants are fundamentally changing this country.

An astonishing number of immigrants and their children - nearly 86 million people - now live in the United States. Together, they have transformed the American experience in profound and far-reaching ways that go to the heart of the country's identity and institutions.

Unprecedented in scope, One Quarter of the Nation traces how immigration has reconfigured America's racial order - and, importantly, how Americans perceive race - and played a pivotal role in reshaping electoral politics and party alignments. It discusses how immigrants have rejuvenated our urban centers as well as some far-flung rural communities, and examines how they have strengthened the economy, fueling the growth of old industries and spurring the formation of new ones. This wide-ranging book demonstrates how immigration has touched virtually every facet of American culture, from the music we dance to and the food we eat to the films we watch and books we read.
