The dual degrees of MA in Sociology and Demography and PhD in Sociology and Demography combine standard Sociology requirements with those of the interdisciplinary Demography program, one of the top four population graduate programs. Dual-degree students declare demography as their major area, which leaves them free to choose a minor area from the many offered by the department. In addition to a course that provides an introduction to the field and a methods class in Demographic Techniques, students choose from a wide array of classes offered in different departments. tudents in the dual-degree program have the same average time-to-degree as other students. The primary difference is that dual-degree students use demography classes in lieu of electives.
