Mexicans (Spanish: Mexicanos) are the citizens and nationals of the United Mexican States. The Mexican people have varied origins with the most spoken language being Spanish, but many also speak languages from 68 different Indigenous linguistic groups and other languages brought to Mexico by expatriates or recent immigration. In 2020, 19.4% of Mexico's population identified as Indigenous.[2] There are currently about 12 million Mexican nationals residing outside Mexico, with about 11.7 million[47] living in the United States. The larger Mexican diaspora can also include individuals that trace ancestry to Mexico and self-identify as Mexican but are not necessarily Mexican by citizenship. The United States has the largest Mexican population in the world after Mexico at 37,186,361 in 2019.[48]
The modern nation of Mexico achieved independence from the Spanish Empire in 1821, after a decade-long war for independence starting in 1810; this began the process of forging a national identity that fused the cultural traits of Indigenous pre-Columbian origin with those of Spanish and African ancestry. This led to what has been termed "a peculiar form of multi-ethnic nationalism"[49] which was more invigorated and developed after the Mexican Revolution when the Constitution of 1917 officially established Mexico as an indivisible pluricultural nation founded on its indigenous roots.[50][51]
