The Short Answer: Nine Districts
Indiana currently has nine congressional districts, meaning it sends nine representatives to the U.S. House of Representatives. This number has been stable since the 2000 census. Following the 2020 U.S. Census,
Indiana's population growth was steady enough to maintain its nine seats, avoiding the loss of representation that affected some other Midwestern states. Each of these nine districts must, by federal law, contain a nearly equal number of people, ensuring the principle of "one person, one vote."
The Once-in-a-Decade Redrawing Process
Every ten years, after the U.S. Census provides updated population counts, states undertake a process called redistricting. In Indiana, the power to draw the new maps for both congressional and state legislative districts falls to the State Legislature. The maps are passed as a bill, which must be signed by the governor to become law. This gives the political party in control of the General Assembly and the governor's office significant influence over how the lines are drawn. Following the 2020 census, this process took place in the fall of 2021.
What Changed in the 2021 Remap?
On October 4, 2021, Governor Eric Holcomb signed the new district maps into law, which were drafted and passed by the Republican-controlled legislature. While the state kept its nine districts, the boundaries of those districts were significantly altered. The new maps took effect for the 2022 elections. One of the most notable changes occurred in the 5th Congressional District in the Indianapolis suburbs. The new map removed the northern portion of Marion County from the district, a move widely seen as an effort to make the district more reliably Republican for incumbent Victoria Spartz. Her previous win in 2020 was by a relatively narrow margin, and the redrawn boundaries consolidated Republican-leaning areas. Other districts were also adjusted, with mapmakers stating the goal was to create more compact districts and keep more counties whole.
The Politics of New Lines
The 2021 redistricting process was criticized by Democrats and voting rights advocates as an act of partisan gerrymandering, the practice of drawing districts to give one political party an unfair advantage. The final maps were passed on a party-line vote in the legislature, with no Democrats voting in favor. Critics argued that the new boundaries were designed to solidify the Republican majority, which held seven of the nine congressional seats, by packing Democratic voters into the two districts they already held (the 1st and 7th) and spreading Republican voters efficiently across the others. Proponents of the maps defended them as fair, compact, and compliant with all legal requirements. The result, however, is a congressional delegation that is not reflective of the state's overall political breakdown, where Democrats regularly receive over 40% of the statewide vote but hold just over 22% of the congressional seats.
Why It Matters for Hoosier Voters
These new boundaries will shape Indiana's political landscape for the next decade. The way districts are drawn has a direct impact on voters. It can determine whether elections are competitive or foregone conclusions. When a district is drawn to be overwhelmingly Republican or Democratic, it reduces the incentive for elected officials to compromise or appeal to a broader range of constituents. It can also split communities of interest—neighborhoods, cities, or counties with shared concerns—diluting their collective voice and making it harder for their needs to be addressed in Congress. While reform efforts to create an independent redistricting commission have been unsuccessful in Indiana, the debate over who should draw the lines, and how, continues.
