Computational social science (CSS) is the science that investigates social phenomena through the medium of computing and related advanced information processing technologies. The purpose of the Computational Social Science Society of America (CSSSA) is to promote the field of computational social science in all its areas, including basic and applied orientations, by holding conferences and workshops, promoting standards of scientific excellence in research, teaching, and service, and by advancing the role of CSS in contemporary society.

The areas of CSSSA include theory and research in social simulation models, including

• Agent-based modeling
• Evolutionary computation
• System dynamics
• Microsimulation
• Networks
