Some of the brightest minds in math arrived at Tufts University last week to tackle an issue lawyers and political scientists have been struggling with for decades. They came from colleges across the country for a weeklong conference on gerrymandering, the practice of crafting voting districts in a way that favors voters from a certain political party or demographic. It’s a topic of growing interest among many math and data experts who say their scholarly fields can provide new tools to help courts identify voting maps that are drawn unfairly. Among those working to bridge the classroom and the courtroom is Moon Duchin, a math professor at Tufts who orchestrated the gathering at her Boston-area campus. The workshop was the first in a series being organized at campuses nationwide to unite academics and to harness cutting-edge mathematics to address gerrymandering.
“Mathematicians are coming late to this problem,” said Duchin, who started studying the shapes of electoral districts after teaching a course on voting during the presidential primary last year. “We think we can see underlying mathematical principles that weren’t visible before.”
Gerrymandering isn’t new, and it isn’t always illegal. States are given wide latitude to draw their own voting districts, and since at least the 1800s politicians have sought to cement their power by creating districts in which certain voting groups are spread thinly over many districts or clumped heavily into only a few. Either way, it dilutes their power.
