Penn State University: Twitter data changing future of population research. “Twitter may have started out as a way to connect to other people and share news quickly, but the social media platform is also a powerful tool, with the data generated representing the largest publicly accessible archive of human behavior in existence. Guangqing Chi, associate professor of rural sociology and demography and public health sciences in Penn State’s Department of Agricultural Economics, Sociology, and Education and director of the Computational and Spatial Analysis (CSA) Core in the Social Science Research Institute, and his team have collected over 30 terabytes of geo-tagged tweets over the last four years.”
