New Mexico is a southwestern state in the United States of America. Over its relatively long history it has also been occupied by Native American populations and has been part of the Spanish viceroyalty of New Spain, a state of Mexico and a U.S. territory. Among U.S. states, New Mexico has simultaneously the highest percentage of Hispanic Americans (some recent immigrants and others descendants of Spanish colonists) and the second-highest percentage of Native American after Alaska (mostly Navajo and Pueblo peoples). As a result, the demographics and culture of the state are unique for their strong Spanish, Mexican, and U.S. Amerindian cultural influences. The United States Census Bureau estimates that the state population was 1,954,599 in 2006, a 7.45% increase since 2000.
