New Mexico is organized into several overlapping sets of districts, each tied to a different function of government. There are three U.S. congressional districts, 112 state legislative districts split between a 70-member House and a 42-member Senate, 13 judicial districts that organize the trial courts, and 10 Public Education Commission districts that oversee state-chartered schools. All of these sit on top of 33 counties, which handle most day-to-day local government. The layer you fall into determines who represents you, which courthouse hears your case, and which commissioner votes on charter schools in your area.
The 33 Counties Underneath Everything
Counties are the base layer. New Mexico has 33 of them, and they handle the services residents interact with most often: property records, rural road maintenance, sheriff’s offices, zoning outside city limits, and local emergency response. Each county is run by an elected commission, and county offices like the clerk, treasurer, and assessor manage the records that drive property ownership, taxes, and elections. County lines have been stable for decades, which is not true of the legislative and congressional boundaries drawn on top of them.
Three Congressional Districts
New Mexico holds three seats in the U.S. House of Representatives, one per district. The First District covers the central part of the state and is anchored by the Albuquerque metropolitan area. The Second District runs across the southern region, taking in agricultural land and border communities near Arizona and Texas. The Third District covers the north, including Santa Fe and the rural areas extending toward Colorado.
These three districts are redrawn after each decennial census so that each contains roughly the same number of people. The U.S. Constitution requires congressional districts to be as equal in population as practicable, a standard the Supreme Court set in its 1964 ruling in Wesberry v. Sanders.1Congress.gov.

112 State Legislative Districts
The state legislature meets in Santa Fe and is split between a 42-member Senate and a 70-member House of Representatives, for 112 legislative districts in total. House members serve two-year terms; senators serve four. These boundaries are drawn independently of the congressional lines and are focused on state-level lawmaking, including the state budget, criminal statutes, tax policy, and funding for schools and infrastructure.
One feature sets New Mexico apart from most other state legislatures: members receive no salary. They are paid a per diem of $202 for each day the legislature is in session, which covers lodging and meals.2New Mexico Legislature. Per Diem and Mileage Rates for Legislators The legislature meets for 60 days in odd-numbered years and 30 days in even-numbered years. Even-year sessions are limited to budget matters, bills based on a governor’s message, and vetoed bills from the previous session.
13 Judicial Districts
The state’s trial courts are organized into 13 judicial districts, authorized by Article VI of the state constitution and spelled out in statute.3FindLaw. New Mexico Constitution Art VI 12 – Judicial Districts Judges Each district covers one or more of the 33 counties, and the district courts handle felony trials, major civil cases, family law matters, and appeals from lower courts. The county assignments are set by NMSA Section 34-6-1.4Justia. New Mexico Statutes Section 34-6-1 – Judicial Districts
A few examples give a sense of the range. The Second Judicial District covers Bernalillo County alone, which includes Albuquerque, and carries the heaviest caseload in the state. The Third District is Doña Ana County, home to Las Cruces. The First District covers Santa Fe, Rio Arriba, and Los Alamos counties. Multi-county districts like the Seventh (Socorro, Torrance, Sierra, and Catron) and the Tenth (Quay, DeBaca, and Harding) cover enormous geographic areas with far fewer residents, which means judges travel between courthouses more often.
Filing a new civil case in any district court costs $132.5Eighth Judicial District. Fees, Costs and Filing – Eighth Judicial District That fee applies broadly to tort claims, contract disputes, probate matters, and other civil actions. Jurors are drawn from the community within the district where the case is filed.
10 Public Education Commission Districts
The Public Education Commission is a 10-member elected body, with each commissioner representing a distinct geographic district. Its core job is authorizing new state-chartered schools, monitoring their performance, and deciding whether to renew existing charters. When an applicant proposes a new state-chartered school, the commission holds at least one public hearing in the local school district before voting, and it cannot charge an application fee.6Justia. New Mexico Statutes Section 22-8B-6 – Charter School Application
One boundary matters: Public Education Commission districts do not control traditional public schools. Those are run by locally elected school boards. The commission’s authority is limited to charter schools operating under state-level authorization.
How the Lines Get Redrawn
After each federal census, New Mexico redraws its congressional and state legislative districts under the Redistricting Act at NMSA Sections 1-3A-1 through 1-3A-9. The act created the Citizen Redistricting Committee, an independent body that develops proposed maps and submits them to the legislature for approval.7Justia. New Mexico Statutes Section 1-3A-3 – Citizen Redistricting Committee Created Membership Terms
The statute sets specific rules. Congressional districts must be as equal in population as practicable. State legislative districts must be substantially equal, with no plan exceeding a total population deviation of 10 percent. Districts must be contiguous and reasonably compact, and the committee must preserve communities of interest and respect political and geographic boundaries, including those of Indian nations, tribes, and pueblos.8Justia. New Mexico Statutes Section 1-3A-7 – District Plans
The law also guards against partisan manipulation. The committee cannot use voting history or party registration data when drawing lines, except to verify compliance with the federal Voting Rights Act. It also cannot consider where current officeholders live unless ignoring that information would conflict with other redistricting principles.8Justia. New Mexico Statutes Section 1-3A-7 – District Plans
Federal law sets a floor on top of those state rules. The Equal Protection Clause of the Fourteenth Amendment requires state electoral districts to contain approximately equal populations, the “one person, one vote” principle the Supreme Court applied to state legislatures in Reynolds v. Sims (1964).1Congress.gov. Equality Standard and Vote Dilution Section 2 of the Voting Rights Act adds a separate layer, prohibiting plans that dilute minority voting strength. If race becomes the predominant factor in how a map is drawn, courts apply strict scrutiny and require the state to show a compelling justification.9Congress.gov.
