In 2019, as the federal government began preparations for the 2020 U.S. Census, Associate Professor of Mathematics and Computer Science Courtney Thatcher was doing a lot of thinking about the problem of redistricting. Every 10 years, population data from the census is used by states to redraw election maps. In theory, this redistricting process ensures that there are the same number of people in each district, giving them equal representation in Congress. In practice, this process is often mired in partisan attempts to gerrymander districts to benefit one political party.
