D'Antonio, Dillon, and Gautier have written a report on the fifth survey (administered in 2010) in a series of opinion polls of the American Catholic laity that started in 1987. Responses were analyzed by generation, gender, and ethnicity, with attention to the increasing impact of Hispanic Catholics. Many trends established in the earlier studies have stayed on the same trajectory, with a few changes. Core beliefs remain strong, the magisterium carries relatively little weight with the laity, and certain areas (the importance of the sacraments, Mary the Mother of God, and helping the poor) continue to differentiate Catholics from others. On the other hand, a decreasing commitment on the part of American women to the church is evident. Hispanics often are more traditional in their responses, but the authors do not discuss whether this will change with economic and cultural assimilation. The study is clear and readable. The authors clearly have a bias toward what one might call the 'progressive' direction in American Catholicism. At times one can see that a different grouping of the data would present a different picture. Summing Up: Recommended. Lower-division undergraduates through researchers/faculty.
