New Mexico (Spanish: Nuevo México [ˈnweβo ˈmexiko] (listen); Navajo: Yootó Hahoodzo [joː˩tʰo˥ ha˩hoː˩tso˩]) is a state in the Southwestern United States. It is one of the Mountain States of the southern Rocky Mountains, sharing the Four Corners region of the western U.S. with Utah, Colorado, and Arizona, and bordering Texas to the east and southeast, Oklahoma to the northeast, and the Mexican states of Chihuahua and Sonora to the south. The state capital is Santa Fe, which is the oldest capital in the U.S., founded in 1610 as the government seat of Nuevo México in New Spain; the largest city is Albuquerque. It was admitted as a state in 1912.
New Mexico is the fifth-largest of the fifty states, but with just over 2.1 million residents, ranks 36th in population and 46th in population density. Its climate and geography are highly varied, ranging from forested mountains to sparse deserts; the northern and eastern regions exhibit a colder alpine climate, while the west and south are warmer and more arid; the Rio Grande and its fertile valley runs from north-to-south, creating a riparian climate through the center of the state that supports a Bosque habitat and distinct Albuquerque Basin climate. One–third of New Mexico’s land is federally owned, and the state hosts many protected wilderness areas and national monuments, including three UNESCO World Heritage Sites, the most of any state.
New Mexico’s economy and industries are some of the largest in the country, highlighted by the New Mexico Oil & Gas Association, EMNRD, New Mexico Technology Corridor, media in Albuquerque, and its film industry. And the state has highly diversified sectors in cattle ranching, agriculture, lumber, scientific and technological research, tourism, and the arts, especially textiles and visual arts. Its total gross domestic product (GDP) in 2020 was $95.73 billion, with a GDP per capita of roughly $46,300. State tax policy is characterized by low to moderate taxation of resident personal income by national standards, with tax credits, exemptions, and special considerations for military personnel and favorable industries. Due to its large area and economic climate, New Mexico has a significant U.S. military presence, including White Sands Missile Range, and strategically valuable federal research centers, such as Sandia and Los Alamos National Laboratories. The state hosted several key facilities of the Manhattan Project, which developed the world’s first atomic bomb, and was the site of the first nuclear test, Trinity.
In prehistoric times, New Mexico was home to Ancestral Puebloans, Mogollon, and the modern Comanche and Utes. Navajos and Apaches entered the state towards the end of the 15th century. Spanish explorers and settlers arrived in the 16th century, naming the territory Nuevo México after the Aztec Valley of Mexico, more than 250 years before the establishment and naming of the present-day country of Mexico; thus, the state did not derive its name from Mexico. Isolated by its rugged terrain and the relative dominance of its indigenous people, New Mexico was a peripheral part of the viceroyalty of New Spain. Following Mexican independence in 1821, it became an autonomous region of Mexico, albeit increasingly threatened by the centralizing policies of the Mexican government, culminating in the Revolt of 1837; at the same time, the region became more economically dependent on the United States. At the conclusion of the Mexican–American War in 1848, the U.S. annexed New Mexico as part of the larger New Mexico Territory. It played a central role in U.S. westward expansion and was admitted to the Union as the 47th state on January 6, 1912.
New Mexico’s history has contributed to its unique demographic and cultural character. One of only six majority-minority states, it has the nation’s highest percentage of Hispanic and Latino Americans and the second-highest percentage of Native Americans after Alaska. New Mexico is home to part of the Navajo Nation, 19 federally recognized Pueblo communities, and three different federally recognized Apache tribes. Its large Hispanic population includes Hispanos, who descend from early Spanish settlers, as well as Chicanos and Mexicans. The New Mexican flag, which is among the most recognizable in the U.S., reflects the state’s eclectic origins, bearing the scarlet and gold coloration of the Spanish flag along with the ancient sun symbol of the Zia, a Puebloan tribe. The confluence of indigenous, Spanish, Mexican, Hispanic, and American influences is also evident in New Mexico’s unique cuisine, music genre, and architectural style.
