The book surveys the various methods which may be used in measuring segregation in the labor force. It makes a distinction between the concepts of concentration and segregation, between cardinal measures and an ordinal approach to the topic. It explains also how to decompose changes in segregation. Finally it indicates how to combine the analysis of wage discrimination with that of occupational segregation. In every chapter illustrations are given, based on Swiss data. The book should therefore be very useful to any social scientist interested in these issues.
