The Graduate Group in Sociology and Demography (GGSD) is an interdisciplinary training program in the social sciences designed for students with broad intellectual interests. Drawing on Berkeley's Department of Sociology and Department of Demography, the group offers students a rigorous and rewarding intellectual experience.

The group, founded in 2001, sponsors a single degree program leading to a PhD in Sociology and Demography. The GGSD helps foster an active intellectual exchange between graduate students and faculty in the two disciplines. In addition, faculty and students associated with the group often maintain close ties with other disciplines both inside and outside the social sciences (for example, economics, anthropology, statistics, public health, biology, and medicine).

The specific emphasis of this academic program is the intersection of the fields of sociology and demography. Potential areas of study include, but are not limited to: population history, social stratification, inequality, race, ethnicity, causes and consequences of population growth, the demographic transition, population-environment interactions, economic development, immigration, globalization, gender, family, kinship, child welfare, sexuality, intergenerational relations, aging, mortality, health care, disability, fertility, family planning, and birth control.

Students in the GGSD typically earn both an MA in Sociology and an MA in Demography en route to the PhD in Sociology and Demography; however, it is not required to earn an MA in Sociology to get the PhD in Sociology and Demography. Students already enrolled in another graduate program at Berkeley who wish to earn a PhD in Sociology and Demography should contact the Graduate Student Affairs Officer to receive application instructions. Students not already enrolled at Berkeley who wish to enter the PhD program should complete the required online application. The general deadlines for the application specified by the Graduate Division apply, as do the general requirements of the Academic Senate and the Graduate Division for PhD degree programs.
