Based on the 2010 census, North Carolina’s total number of congressional districts remained the same during the reapportionment process—13 House seats. But not every district drawn 10 years earlier that was based on the 2000 Census data grew at the same rate over the decade. There was significant variation in population growth across the state: major metropolitan areas grew rapidly, while other areas experienced slow growth or population declines. North Carolina’s post-2010 redistricting process required adjusting the district boundaries based on the 2000 Census to account for these different rates of population growth.


In 2010, North Carolina’s total population was 9.5 million. Split equally across 13 congressional districts, this yielded an ideal district size of 733,499 residents. The most over-populated districts were around the state’s two largest metropolitan areas: Charlotte and Raleigh-Durham-Chapel Hill. District 9, around Charlotte, deviated from the ideal district size by nearly 120,000 people or 16.2% more than the ideal number. District 4, comprised of Orange and Durham counties and parts of Wake County, was 12.7% larger than the ideal district size. In contrast, District 1, in Eastern North Carolina, was under-populated. Its population was significantly smaller than the ideal district size (-13.3%), with nearly 98,000 fewer residents than the ideal size.

These population shifts necessitated significant changes in congressional district boundaries during redistricting, but they are not the only demographic criteria considered in redistricting. North Carolina also has two “majority-minority” districts to comply with federal requirements in Section 2 of the Voting Rights Act of 1965. The interactive map linked below highlights the shifts in North Carolina’s congressional district boundaries during the post-2010 redistricting process.
