"Johnson and Grim's book is the benchmark for research ondemography and religion. Their comprehensive discussion of complexissues such as methodology, religious identities, anddiffering measurements, appeals to scholars in manydisciplines working on religion and demographics. Thisbook is going to be the resource future generations of scholarswill build on."--Rachel M. McCleary, Harvard KennedySchool of Government

"I recommend this substantial volume for two reasons: itcontains a huge amount of useful information; it is also veryreadable. As Peter Berger indicates in his Foreword, this isnot a book to be read from cover to cover but rather to be kept athand for reference. True enough. Butonce launched, I found it hard to stop -- the narrative iscompelling."--Grace Davie, University ofExeter
