Where the name comes from
Spanish expeditions pushing north out of Nueva Vizcaya in the 1560s called the country beyond the Rio Grande a new Mexico, after the Mexica empire they expected to find there and never did; Antonio de Espejo was using Nuevo México as a proper name by 1583, two centuries before the modern republic existed. Colonists arrived under Juan de Oñate in 1598. Mexican rule lasted 27 years, from independence in 1821 until the Treaty of Guadalupe Hidalgo handed the territory to the United States in 1848; the Gadsden Purchase of 1853 added the bootheel, and statehood followed on 6 January 1912. The old maps of Mexico show the frontier before and after both treaties.
Santa Fe and the Camino Real
Santa Fe, founded in 1610 as the provincial capital, has been a seat of government ever since — the oldest capital city in the United States and, at 2,194 m, the highest. It stood at the north end of the Camino Real de Tierra Adentro, the royal road running about 2,560 km south through El Paso del Norte, Chihuahua and Zacatecas to Mexico City, in use until the railway replaced it in the 1880s; the Mexican section is a UNESCO World Heritage site. That road is why the adobe architecture, place names and land grants of northern New Mexico read as an extension of northern Mexico, not the American West.
Cities of New Mexico
Roughly half the population lives in the Albuquerque–Santa Fe corridor along the Rio Grande; the eastern plains cities look to Texas, and Las Cruces sits an hour from the border.

Geography
New Mexico covers 314,917 km² (121,590 sq mi), the fifth-largest US state, with 2,117,522 people in 2020 and one of the lowest population densities. It falls into three zones: the Rio Grande rift, which splits the state north to south and carries the river past Albuquerque at 1,619 m below the Sangre de Cristo Mountains and Wheeler Peak (4,013 m); the high plains and Llano Estacado to the east, draining to the Pecos; and the Colorado Plateau to the west, mesa and volcanic-neck country cut by the Continental Divide. Four Corners, in the north-west, is the only place where four US states meet.
Mean elevation is about 1,740 m, second only to Colorado, and altitude sets the climate more than latitude. Albuquerque gets roughly 230 mm of rain a year, over half of it in the July–September monsoon that also soaks Chihuahua and Sonora. Summer highs pass 35 °C in the south while northern mountains hold snow into May. The southern third of the state is the northern tip of the Chihuahuan Desert, mapped on the physical map of Mexico.
Counties
New Mexico has 33 counties. Bernalillo, containing Albuquerque, holds about a third of the population; Catron in the west is the largest at roughly 17,900 km² and had 3,579 residents in 2020. Hidalgo County forms the bootheel; Luna County next door holds Columbus and Deming.
The 23 tribal nations
Twenty-three sovereign tribal governments hold land in New Mexico: the Navajo Nation in the north-west, whose reservation is the largest in the United States at about 71,000 km² across three states; three Apache nations, the Mescalero, the Jicarilla and the Fort Sill Apache; and the 19 Pueblos, farming towns along the Rio Grande and its western tributaries — Taos, Acoma and Zuni among them — some inhabited for a thousand years.
The border with Chihuahua
The frontier with Mexico is 290 km (180 mi) long, almost all of it with Chihuahua and a few kilometres at the tip of the bootheel with Sonora. It is a surveyed straight line, drawn in 1853, not a river boundary. Three ports of entry serve it: Santa Teresa, west of El Paso, which handles most of the freight; Columbus, facing Puerto Palomas de Villa; and Antelope Wells, the quietest land crossing on the whole US–Mexico border. Columbus is where Pancho Villa's column attacked at dawn on 9 March 1916, killing about 18 Americans and prompting Pershing's eleven-month Punitive Expedition into Chihuahua.

Economy and language
Federal science is the largest single employer: Los Alamos National Laboratory, built in 1943 for the Manhattan Project, and Sandia National Laboratories in Albuquerque together employ more than 30,000 people. The first nuclear test was fired at the Trinity site near Socorro on 16 July 1945, and White Sands Missile Range still holds a block of desert larger than some states. Lea and Eddy counties sit over the New Mexico share of the Permian Basin, second only to Texas among US oil producers at roughly two million barrels a day. A tax rebate has drawn film studios to Albuquerque since the 2000s.
About 28 per cent of New Mexicans speak Spanish at home and about 48 per cent identify as Hispanic or Latino, both the highest shares of any state. Traditional New Mexican Spanish descends from colonial speech of the 1600s, and the 1912 constitution required laws to be published in both languages, though the state has no official language.

Questions about New Mexico
Is New Mexico part of Mexico?
No. New Mexico is a state of the United States, admitted in 1912. It was Spanish (1598–1821) and then Mexican (1821–1848) territory, which is where the name comes from; the region was called Nuevo México by the Spanish decades before the country of Mexico existed.
Why is it called New Mexico?
Spanish expeditions in the 1560s used the phrase for the country north of the Rio Grande, hoping to find a second Mexica empire there. Antonio de Espejo was writing Nuevo México as a proper name by 1583, more than two centuries before the modern republic of Mexico existed.
What is the capital of New Mexico?
Santa Fe, founded in 1610 — the oldest state capital in the US. The largest city is Albuquerque.
Does New Mexico border Mexico?
Yes, for 290 km (180 mi) along Chihuahua and a short stretch of Sonora, with crossings at Santa Teresa, Columbus and Antelope Wells.
How far is Albuquerque from the Mexican border?
About 390 km (240 mi) to the Santa Teresa crossing west of El Paso, roughly a four-hour drive south on Interstate 25. Ciudad Juárez is about 440 km from Albuquerque.
