According to the Census Bureau, “Congressional districts are the 435 areas from which members are elected to the U.S. House of Representatives.” Each congressional district in a state has an equal population and thus changes when the population changes, which is recorded by the Census every 10 years.

Each time new Census population data is released, the states begin a process called “redistricting” that redraws congressional district lines based on population changes. This process started most recently in 2020, and the 2022 midterm elections will reflect the new districts.

When district lines are redrawn, the voting population changes as well. FiveThirtyEight created a partisan lean metric to measure the partisanship of each district. They define “partisan leaning” as “the average margin difference between how a state or district votes and how the country votes overall.” You can learn more about how they created their leaning scores here.

So, knowing this, how did district lines in Maryland change?
