The critical study of sociology of stratums and social inequalities book

The sociology of stratums and social inequalities book by RasoulRabani and Abraham Ansari was evaluated for improving of human science resources. Of the book advantages are the study of social inequalities dimensions as some subjects as women and social stratum, religions and social stratum, ethnics and social inequalities, policy and social stratum and two chapters as subject as the case study of  middle class  in Iran and USA. The formal generality factors have not been regarded as an educational book in university. The formal and content evaluation shows that this book doesn’t meet the need of scientific society in sociology of stratum and social inequalities field despite of the third edition because the book isn’t problem- oriented, it has no the theoretical presupposition and methodology and the book content has not been arranged around of main question and if the book is subject –oriented, itisn’t as a book as educational and scientific one and furthermore, it is similar to an article collection.
