The Short Answer: Nine Districts
For the 2026 elections, Indiana will have nine congressional districts. Each of these districts elects one person to represent them in the U.S. House of Representatives in Washington, D.C. This number has been stable for over two decades, holding firm since the apportionment that followed the 2000 Census. Following the 2020 Census, Indiana's population growth was enough to maintain its nine seats, while other states in the Midwest saw their congressional delegations shrink. These nine representatives are the state's direct line to the federal lawmaking process, influencing everything from national policy to local funding.
How That Number Gets Decided: Apportionment
The number of congressional districts isn't arbitrary; it's determined by a constitutional process called apportionment that
happens once every decade. After the U.S. Census Bureau completes its nationwide count, the 435 seats in the House of Representatives are divided among the 50 states based on their population. States with faster-growing populations can gain seats, while those with slower growth or population loss can lose them. Indiana's population grew to nearly 6.8 million in the 2020 Census, an increase of about 4.7 percent from 2010. While not a staggering boom, it was enough for the state to avoid losing a seat, a fate that befell neighbors like Illinois and Ohio. Historically, Indiana's representation has fluctuated, peaking at 13 seats for a long stretch from the 1870s until the 1930s before gradually declining.
Drawing the Lines: The Politics of Redistricting
Once a state knows how many seats it has, the next step is to draw the district boundaries, a process known as redistricting. In Indiana, this power rests with the state legislature, the General Assembly. Following the release of detailed census data, lawmakers draw and vote on new maps for both congressional and state legislative seats, which are then signed into law by the governor. The current maps were passed by the Republican-controlled legislature and signed by Governor Eric Holcomb in October 2021. This process is inherently political, as the way lines are drawn can significantly influence which party is more likely to win an election in a given district. The 2021 maps solidified a landscape that, in practice, heavily favors the GOP, resulting in a consistent 7-2 Republican majority in Indiana's congressional delegation in the elections that followed.
A Mid-Cycle Shakeup That Wasn't
The map used for the 2022 and 2024 elections was nearly redrawn in late 2025. In a dramatic mid-decade push, the Indiana House passed a new map that aimed to create a 9-0 Republican sweep by cracking Democratic strongholds in Indianapolis and Lake County. The proposed map would have dismantled the districts currently held by Democrats André Carson and Frank Mrvan, splitting their voter bases across several heavily Republican districts. However, the effort failed in the Indiana Senate when a significant number of Republican senators joined Democrats to vote down the bill in December 2025. Their opposition ensured that the 2021 map, with its two Democratic-leaning districts, will remain in place for the 2026 elections. As a result, the primary battlegrounds are expected to be familiar, with the most competitive race likely to be in the 1st District in Northwest Indiana.
