Jacob R Brown

2022-2023 CSDP Fellow
Corwin 236

Jacob Brown earned his PhD in Government and Social Policy at Harvard University in 2022. He studies political behavior in American politics with particular interest in how political geography and group identity structure political behavior. His work investigates the behavioral consequences of geographic partisan polarization, with specific focus on how this polarization is self-reinforcing: how living in increasingly homogeneous partisan environments influences voters’ political affiliations. To this end, Jacob develops data on the partisan residential exposure of every voter in the United States over the past decade, leveraging precise information on each voter's residential location, partisan affiliation, and political behavior. With these data he presents new evidence on the extent and causes of partisan sorting in the United States and test new theories of how where Democrats and Republicans live in relation to one another influences political behavior. Jacob will continue this work as a CSDP fellow and in 2023 will join the political science faculty at Boston University as an assistant professor.
