What is the oldest way of measuring social change​

In 1933, President Herbert Hoover commissioned the "Ogburn Report," a comprehensive study of social trends in the United States. Fifty years later, a symposium of noted social and behavioral scientists marked the report's anniversary with a book of their own from the Commission on Behavioral and Social Sciences and Education. The 10 chapters presented here relate the developments detailed in the "Ogburn Report" to modern social trends. This book discusses recent major strides in the social and behavioral sciences, including sociology, psychology, anthropology, economics, and linguistics.
