Back in August 2021, the U.S. Census Bureau released the data needed to perform redistricting, which is required by law, after the once in a decade headcount. The data showed that County Commission District 4 had the largest population growth over the last 10 years. Below is the graph of the 2020 Census results by County commission district.

Redistricting FAQ

What is redistricting?

Redistricting is the regular process of adjusting the lines of voting districts in accordance with population shifts. For many states, this means redrawing congressional and state legislative district lines every ten years following the decennial census. In the modern era of redistricting, all district lines must be reviewed after the census to meet strict requirements for population equality and voting rights protections.
The U.S. Census Bureau has redistricting videos to better explain the required process.

How does redistricting differ from reapportionment?

Reapportionment is the process of reassigning congressional seats among the states after the Census. During the last decade, New Mexico experienced a slight population increase; therefore, the state did not lose a congressional seat. All states, even those that did not gain or lose seats, still must redraw district boundaries to match internal population shifts. The goal is to have equal numbers of people in every district, nationwide. This works to ensure equal representation of each district resident and attempts to avoid the drawing of boundaries for the purposes of partisan advantage or protection of the incumbent party.
