Based on 3,522 one- to two-hour personal interviews conducted in 1973, this study compares the 1973 views and attitudes of American youth to a survey conducted in the late 1960's. As a result, significant trends are traced through an era filled with events that deeply affected the lives of young people, such as the peak and ending of the Vietnam war. Changing values under examination include sexual morality; attitudes toward authority, religion, and obligations toward others; social values dealing with attitudes toward the work ethic; marriage, family, and the importance of money in defining the meaning of success; and self-fulfillment. While the largest portion of the sample contains college youth, other people between the ages of 16 and 25 are examined including high school students, blue collar workers, housewives, and high school dropouts. The report is divided into three major sections containing 15 chapters. Section 1 provides an overview and interpretation of the data. Section 2 presents the research contrasting the values of college and noncollege youth. Section 3 presents the research for selected groups such as blue collar workers, minority youth, high school students, women, Vietnam veterans, college graduates in the work force, and the unemployed.
