An accessible, richly illustrated overview of how unprecedented racial change is remaking the United States. Race is once again a contentious topic in America, as shown by the divisive rise of Donald Trump and the activism of groups like Black Lives Matter. Yet, Diversity Explosion argues that the current period of profound racial change will lead to a far less divided nation than many fear. Prominent demographer William Frey sees America's emerging diversity boom as good news for a country that would otherwise become isolated from the rest of world while facing declining growth and rapid aging for years to come. In this updated and revised third edition of his award-winning book, Frey draws lessons from the 2020 and 2024 presidential elections and fresh statistics to paint a clear picture of where America's racial demography is headed—and what it means for the nation's future. Drawing from the most recent U.S. Census, recent national surveys, and related sources, Frey tells how the rapidly growing “new minorities”—Hispanics, Asians, and multiracial Americans—along with African Americans and other groups, are transforming and reinvigorating communities from cities to suburbs and from the coasts to the heartland. He discusses their impact on generational change, neighborhood segregation, and interracial marriage, as well as presidential politics.
