American Jews have divided their religion into four parts-Orthodox, Conservative, Reform, and no preference Jews. This book focuses on how Jewish lifestyles are expressed through denominational affiliation.

The development of American Jewish denominations is viewed as more a matter of individual choice than family heritage. The characteristics of individual adherents of the three major denominations vary systematically as does one's involvement both in local Jewish communities and in the community-at-large. The authors show that as one goes from Orthodox to no preference Jews, the extent of religious expression, ethnic attachments, and Jewish community involvement declines.

They project the distribution of denominational preference in 2010 and conclude with recommendations for those who wish to see Jewish identity survive and thrive in America.
