This book explores the state of the American Jewish world in the early 21st century, after decades of accelerating change that has transformed it and all other religious groups in the United States. It reveals a community in an unparalleled state of flux grappling with a society in which religious identity is more and more considered an individual choice, rather than an inheritance, and where fewer adults feel impelled to identify with any religious tradition at all. In chapters written by leading experts, the book examines the community’s evolving demographics, the direction of the principal denominational movements, contemporary religious trends, interactions with other American religious communities and engagements in the country’s secular politics. This text uniquely covers all these aspects of Judaism in America making it appealing to students and researchers in such fields as the sociology of religion, Judaism, and American history.
