Los Alamos County (English: "The Poplars" or "Cottonwoods"; Spanish: Condado de Los Álamos) is a county in the U.S. state of New Mexico. As of the 2020 census, the population was 19,419.[1] The smallest county by area in the state, Los Alamos County was formerly administered exclusively by the U.S. federal government during the Manhattan Project, but it now has equal status to New Mexico's other counties. The county has two census-designated places: Los Alamos and White Rock.[2]
Los Alamos County comprises the Los Alamos Micropolitan Statistical Area, which is also included in the Albuquerque–Santa Fe–Los Alamos combined statistical area.
The county is home to the Los Alamos National Laboratory. Los Alamos County is noted for having the lowest level of child poverty of any county in the United States.[3]
