Los Alamos County

Los Alamos County is an administrative division in northern New Mexico with rolling mountainous terrain. A major research facility anchors the region and shapes much of its development and character.

The area began as a secret wartime research project and became an official county in 1949. This foundation in military research established the direction the region would take for decades.

The community here centers on scientific work, with many residents employed in research fields. Education and technical innovation are deeply valued aspects of daily life that shape how people interact and plan their futures.

The terrain is mountainous and at higher elevation, so come prepared for varied weather and steep roads. Services and facilities are concentrated in the central areas of the county.

This county has one of the lowest poverty rates in the country, largely because major employers provide stable, well-paying jobs. This economic stability sets the region apart from many other American communities.
