By Patricia Jones Bernalillo County is the population and economic centre of New Mexico. It contains Albuquerque, the state’s largest city, and combines a major urban core with Rio Grande valley communities, high-desert mesas, tribal lands and mountain settlements east of the Sandia range.
Albuquerque is the county seat and the centre of county administration, state and federal courts, higher education, healthcare, research, military activity and regional transportation. The county government is especially important in unincorporated areas, where it provides planning, roads, fire protection, law enforcement, community facilities and other local services.
Bernalillo County should not be confused with the Town of Bernalillo. Despite the shared name, the Town of Bernalillo is located north of the county in Sandoval County.

The U.S. Census Bureau estimated Bernalillo County’s population at 667,601 on July 1, 2025. The April 2020 census counted 676,444 residents. The recent estimate therefore represents a modest decline from the 2020 base, although the county remains New Mexico’s largest population centre by a wide margin.
Location and Geographic Structure
Bernalillo County occupies the central part of New Mexico. Sandoval County lies mainly to the north, Santa Fe and Torrance counties are to the east, Valencia County is to the south and Cibola County is to the west. The county’s compact shape includes a densely developed urban basin, irrigated river valley, volcanic mesa and forested mountain terrain.
The Rio Grande runs from north to south through the county and divides much of the Albuquerque area into east-side and west-side communities. The Sandia Mountains rise sharply on the eastern side of the metropolitan area. Tijeras Canyon provides the main east-west route through the mountains, while the East Mountains contain rural homes, villages, forest land and recreation areas.
Important geographic features include:
- Rio Grande and its bosque woodland corridor
- Sandia Mountains and Sandia Peak
- Manzano Mountain foothills
- Albuquerque Basin and West Mesa
- Tijeras Canyon
- Petroglyph National Monument and volcanic escarpment areas
- Cibola National Forest lands
- South Valley agricultural and acequia landscapes
- East Mountain forests and high-elevation communities
Interstates 25 and 40 meet in Albuquerque at the regional junction commonly called the Big I. Interstate 25 links the county with Santa Fe, Las Cruces and the Mexican border, while Interstate 40 provides an east-west route towards Gallup, Arizona, the Texas Panhandle and Oklahoma.
Albuquerque International Sunport is the state’s principal commercial airport. Double Eagle II Airport supports general aviation and business activity on the West Mesa. The New Mexico Rail Runner Express connects the Albuquerque area with communities north and south, while Amtrak, freight rail, local buses and regional highways add to the county’s transportation network.
Cities, Villages and Communities
Bernalillo County contains all or parts of five incorporated municipalities:
- City of Albuquerque
- Village of Los Ranchos de Albuquerque
- Village of Tijeras
- City of Rio Rancho, with a small portion extending into the county
- Town of Edgewood, with a portion extending into the county
Albuquerque contains most of the county’s population and employment. Los Ranchos de Albuquerque is a small Rio Grande valley municipality north of central Albuquerque. Tijeras is a mountain village near the junction of Interstate 40 and New Mexico Highway 14. Rio Rancho is primarily in Sandoval County, while Edgewood is primarily in Santa Fe County and also extends into Torrance County.
Major unincorporated areas and communities include:
- South Valley
- North Valley areas outside municipal boundaries
- Paradise Hills and parts of the northwest mesa
- Carnuel
- Cedar Crest
- Sandia Park
- San Antonito
- Chilili
- Cedro and nearby mountain settlements
- Pajarito Mesa and western mesa communities
County Planning and Development Services handles zoning, subdivision review, building permits, code enforcement and related land-use matters in most unincorporated areas. Incorporated municipalities generally maintain their own planning and development systems.
The county also contains sovereign tribal lands and communities, including the Pueblo of Isleta, the Pueblo of Sandia and the To’hajiilee Chapter of the Navajo Nation. Tribal governments exercise authority over their own lands and should not be treated as ordinary county subdivisions.
Population and Housing
Bernalillo County is highly urbanised, but its population is not distributed evenly. Albuquerque accounts for most residents, while the South Valley, North Valley, West Mesa and East Mountains have different development patterns, housing types and service requirements.
Housing ranges from central-city apartments and historic neighbourhoods to suburban subdivisions, valley properties, manufactured homes, rural mountain residences and homes on tribal lands. Rapid growth in neighbouring Sandoval and Valencia counties has also shaped commuting, road use and regional planning within Bernalillo County.
Selected Census figures for 2020-2024 include:
- Median household income: $69,473
- Per-capita income: $40,690
- Residents below the poverty line: 13.7%
- Median owner-occupied home value: $292,900
- Median gross monthly rent: $1,144
- Average journey to work: 22.9 minutes
The county’s population includes university students, military families, federal employees, healthcare workers, retirees, long-established Hispanic and Native communities and residents who have moved to the Albuquerque area from other parts of New Mexico and the United States.
Housing affordability, homelessness, water availability, wildfire risk, ageing infrastructure and access to services remain major planning concerns. Conditions vary considerably between central Albuquerque, suburban areas, the South Valley, western mesa settlements and rural mountain communities.
Economy and Employment
Bernalillo County has the most diversified economy in New Mexico. Albuquerque serves as the state’s principal centre for government, healthcare, higher education, professional services, retail, transportation, tourism and technology.
The county recorded 16,349 employer establishments and 277,465 jobs in 2023. Annual payroll was approximately $15.26 billion. Retail sales totalled about $13.98 billion in 2022, while healthcare and social-assistance organisations generated nearly $7.99 billion in receipts or revenue.
Important economic sectors include:
- Federal, state, county and municipal government
- Healthcare and social assistance
- Higher education and research
- Military and defence-related activity
- Engineering, technology and cybersecurity
- Aerospace and aviation
- Film, television and digital media production
- Construction and real estate
- Retail, restaurants and hospitality
- Transportation, warehousing and logistics
- Tourism, conventions and cultural attractions
- Small businesses and professional services
Major institutions include Sandia National Laboratories, Kirtland Air Force Base, the University of New Mexico, UNM Hospital and large private healthcare systems. These organisations support direct employment as well as contractors, research partnerships, education, housing demand and specialised services.
Film and media production has become a visible part of the Albuquerque economy. The county’s climate, varied landscapes, studios, trained crews and state incentives have attracted feature films, television series and related businesses.
Tourism is supported by Old Town Albuquerque, the Sandia Peak Tramway, museums, Native and Hispanic cultural sites, outdoor recreation and the Albuquerque International Balloon Fiesta. Although many attractions are managed by the city, state, federal government or private organisations, they contribute to countywide employment and tax activity.
County Administration and Government
Bernalillo County is governed by a five-member Board of County Commissioners. Each commissioner represents a geographic district and is elected by voters within that district. The Board adopts ordinances, approves budgets and contracts, sets policy and oversees departments that fall under county administration.
The current commissioners are:
- District 1: Barbara Baca
- District 2: Frank Baca
- District 3 and vice chair: Adriann Barboa
- District 4: Walt Benson
- District 5 and chair: Eric Olivas
The Board’s principal responsibilities include:
- Adopting the annual operating and capital budget
- Approving ordinances, resolutions and county policies
- Making land-use decisions in unincorporated areas
- Authorising major contracts and capital projects
- Funding county departments and elected offices
- Setting priorities for roads, public safety and community facilities
- Appointing the county manager, county attorney and board members
- Coordinating with Albuquerque, other municipalities, tribal governments and the State of New Mexico
Bernalillo County employs approximately 2,500 people and manages operating, capital and other funds totalling more than $1 billion. Its main administrative headquarters is Alvarado Square at 415 Silver Avenue SW in downtown Albuquerque.
County Manager and Administrative Leadership
Cindy Chavez serves as Bernalillo County manager. The county manager is the chief appointed administrative officer and is responsible for implementing the policies and budget approved by the Board of County Commissioners.
Major responsibilities of the county manager include:
- Supervising appointed departments and senior managers
- Preparing and administering the county budget
- Implementing Board policies and strategic priorities
- Coordinating public safety, public works and community-service operations
- Monitoring employee performance and organisational standards
- Overseeing capital projects and major contracts
- Advising commissioners on administrative and financial matters
- Representing the county in intergovernmental discussions
The manager works through deputy county managers and department directors responsible for areas such as finance, public works, public safety, behavioural health, community services and general services.
The county manager does not exercise direct control over independently elected offices such as the Sheriff’s Office, Assessor’s Office, Clerk’s Office, Treasurer’s Office or Probate Court. Those offices receive county funding but have legal authority established separately by New Mexico law.
Other Important County Officials
Current countywide elected officials include:
- Sheriff: John Allen
- County assessor: Damian Lara
- County clerk: Michelle S. Kavanaugh
- County treasurer: Tim Eichenberg
- Probate judge: Cristy J. Carbon-Gaul
Sheriff John Allen leads the Bernalillo County Sheriff’s Office. The office provides law-enforcement services in unincorporated areas and performs investigations, traffic enforcement, civil process, search support and other countywide functions. Albuquerque Police Department is the primary municipal police agency within Albuquerque city limits.
Assessor Damian Lara is responsible for identifying, classifying and valuing taxable property. The Assessor’s Office maintains parcel information and administers exemptions and valuation procedures under state property-tax law.
Clerk Michelle S. Kavanaugh maintains public records, records real-estate documents, issues marriage licences and administers voter registration and elections within the county.
Treasurer Tim Eichenberg collects property taxes, manages county funds and distributes revenue to the county, municipalities, school districts and other taxing authorities.
Probate Judge Cristy J. Carbon-Gaul presides over the county Probate Court, which handles eligible informal and uncontested estate matters. Disputed or complex probate cases are handled by the state District Court.
The county attorney is appointed by and reports to the Board of County Commissioners. That office provides legal advice and representation to the county government; it is separate from the Second Judicial District Attorney, who prosecutes state criminal cases.
Judiciary and Court System
Bernalillo County has a more complex court structure than most New Mexico counties because it is served by both the Second Judicial District Court and the Bernalillo County Metropolitan Court.
Second Judicial District Court
The Second Judicial District Court is the state trial court of general jurisdiction for Bernalillo County. Its main courthouse is at 400 Lomas Boulevard NW in Albuquerque. Judge Marie Ward serves as chief judge, and Katina Watson serves as court executive officer and clerk.
The District Court handles:
- Felony criminal cases
- Major civil disputes
- Divorce, child custody and family proceedings
- Children’s Court and juvenile matters
- Probate cases outside the limited county Probate Court process
- Mental-health and competency proceedings
- Appeals and reviews authorised under New Mexico law
The Second Judicial District is New Mexico’s largest district court and is organised into civil, criminal, family and children’s court divisions, along with specialty programmes and administrative units.
Bernalillo County Metropolitan Court
The Bernalillo County Metropolitan Court is a state court of limited jurisdiction that serves Albuquerque and the wider county. Judge Joshua J. Sanchez was re-elected chief judge in April 2026. Judge Michelle Castillo Dowler serves as presiding judge of the Criminal Division, and Judge Jason M. Jaramillo serves as presiding judge of the Civil Division.
The Metropolitan Court has 19 judges and handles:
- Petty misdemeanours
- Driving while impaired cases
- Domestic-violence matters
- Traffic violations
- Civil disputes involving up to $10,000
- Felony first appearances and preliminary examinations
- Specialty and treatment-court programmes
Albuquerque Municipal Court separately hears city-ordinance violations and other matters within its municipal jurisdiction. Federal cases are heard by the U.S. District Court for the District of New Mexico, whose principal courthouse is also located in Albuquerque.
Public Safety and Emergency Services
Public-safety responsibility depends on location and the type of incident. Bernalillo County Sheriff’s Office patrols unincorporated areas and carries out specialised countywide duties. Albuquerque Police Department serves the City of Albuquerque, while other municipalities and tribal governments maintain or arrange their own law-enforcement services.
Bernalillo County Fire Rescue provides fire suppression, emergency medical response, rescue and prevention services in unincorporated areas and designated service zones. Albuquerque Fire Rescue serves the city, while tribal and neighbouring jurisdictions operate separate departments.
The county operates the Metropolitan Detention Center, the principal local detention facility for people awaiting trial or serving qualifying sentences. The detention centre is a county department and is administratively separate from the Sheriff’s Office.
County public-safety and emergency functions also include:
- Emergency Communications and 911 dispatch
- Emergency Management
- Animal Care Services
- Youth Services Center
- Behavioural-health crisis programmes
- Wildfire mitigation and community preparedness
- Flood, severe-weather and hazardous-material planning
- Coordination with municipal, tribal, state and federal agencies
The East Mountains face significant wildfire and winter-weather risks. Valley and mesa areas may experience flash flooding, extreme heat and dust. Emergency plans therefore vary by geography and require cooperation among multiple jurisdictions.
Infrastructure and Public Services
Bernalillo County provides a broad range of services, with the greatest direct local-government role in unincorporated areas. Responsibility is divided among the county, municipalities, tribal governments, the State of New Mexico and independent authorities.
Major county services include:
- Road construction and maintenance in unincorporated areas
- Planning, zoning, subdivision review and building inspections
- Parks, open space, trails and community centres
- Senior and social-service programmes
- Housing and community-development assistance
- Animal care and field enforcement
- Public health and environmental-health services
- Behavioural-health initiatives
- Elections and public records
- Property assessment and tax collection
- Economic development and workforce support
- Solid-waste and clean-community programmes
Road ownership must be checked carefully. Albuquerque streets are generally maintained by the city, state highways by the New Mexico Department of Transportation, tribal roads by the relevant tribal authority and county roads in unincorporated areas by Bernalillo County Public Works.
The Albuquerque Bernalillo County Water Utility Authority is a separate regional authority that provides water and wastewater service across much of the metropolitan area. Rural and mountain properties may depend on wells, septic systems, mutual domestic associations or smaller utilities. The county does not operate one unified water system for every property.
Transit is similarly shared. The City of Albuquerque operates ABQ Ride, the State of New Mexico operates the Rail Runner Express, and regional agencies manage highways, airports and rail facilities. County planning decisions still affect access, drainage, road connections and development in unincorporated areas.
