There are 33 counties in the U.S. state of New Mexico.
The New Mexico Territory was organized in September 1850. The first nine counties in the territory to be created, in 1852, were Bernalillo, Doña Ana, Rio Arriba, San Miguel, Santa Ana, Santa Fe, Socorro, Taos, and Valencia Counties. Mora County was created in 1860. Following the Gadsden Purchase of 1853–1854, the northeasternmost part of the New Mexico Territory was ceded to the new Colorado Territory in February 1861, before the western half was reorganized as the Arizona Territory in February 1863, establishing New Mexico's present-day boundaries.
Grant County was created in 1868, followed by Colfax and Lincoln Counties in 1869. In 1876, Santa Ana County was absorbed by Bernalillo County. A further 14 counties were then created between 1884 and 1909, bringing the total number to 26.
New Mexico was admitted to the Union as the 47th state on January 6, 1912. De Baca and Lea Counties were created in 1917, followed by Hidalgo County in 1920 and Catron and Harding Counties in 1921. Los Alamos County was created in 1949 and finally Cibola County in 1981, bringing the total number of counties to 33.
The Federal Information Processing Standard (FIPS) code, which is used by the United States government to uniquely identify states and counties, is provided with each entry.[1] New Mexico's code is 35, which when combined with any county code would be written as 35XXX. The FIPS code for each county links to census data for that county.
