Researchers reveal when U.S. could become the world’s biggest Spanish-speaking nation
The United States could become the country with the largest number of Spanish speakers in the world by 2050, surpassing Mexico and Spain.

In March, President Donald Trump signed an executive order declaring English the official language of the United States. Still, given the millions of immigrants living in the country, other languages remain vital.
Spanish has long had a strong presence in the U.S. The Hispanic community is the nation’s largest minority group, and it’s no surprise that Spanish is the second most widely spoken language in American households, according to the U.S. Census Bureau.
Historically, Spanish-speaking populations were concentrated in the South, especially states along the Mexican border and those closer to Central and South America. That’s still true today: in New Mexico, California, Texas, and Arizona, at least 30% of residents are Hispanic. But the picture is shifting, as younger generations integrate more fully into American society and increasingly settle across the country.
The number of Spanish speakers in the U.S. could rise dramatically in the coming decades, potentially surpassing 100 million. That would make the United States the largest Spanish-speaking country in the world, bigger even than Spain or Mexico.
Could Spanish one day surpass English?
Linguist Humberto López Morales has analyzed demographic trends to understand how Spanish use might evolve. His research suggests that Spanish could become the dominant language in the United States by 2050.
According to Census Bureau data, 41.7 million people in the U.S. spoke Spanish in 2019. López Morales projects that number could top 100 million by 2050: “By 2050, Hispanics will number 102.8 million, even accounting for mortality rates. With such a majority, the country’s politics could see profound changes.”
He adds: “If these projections hold, Mexico could hand over its crown to the United States, which by 2050 may well become the world’s largest Spanish-speaking nation.”
It’s worth noting that these predictions, while striking, remain uncertain. Demographic and cultural trends are always subject to change but there is an underlying shift that suggests that Spanish is becoming more, not less, important.
