The United States has no official language. That fact alone surprises many people, but it reflects something fundamental about how the country was built: from the start, it was a place where dozens of tongues coexisted. Today, that reality is more pronounced than ever.
According to the U.S. Census Bureau, 500 languages are spoken or signed across the country, 177 of them indigenous to U.S. soil or its territories.
The number of people speaking a language other than English at home nearly tripled between 1980 and 2019, climbing from 23.1 million to 67.8 million, or roughly 1 in 5 Americans. Approximately 9 percent of the U.S. population, more than 25 million people, are classified as having limited English proficiency, according to the Migration Policy Institute.
Understanding which languages those people speak, and where, is not just a curiosity. It has direct consequences for healthcare, education, civic participation, and commerce.
Spanish: The Most Spoken Non-English Language by a Wide Margin
Spanish is not a close second to English in the United States. It dominates the non-English landscape by a factor that makes every other language look marginal. According to the U.S. Census Bureau, Spanish accounted for 62 percent of all non-English language speakers at home in 2019, making it twelve times more prevalent than the next four most common languages combined.
Over 43 million people spoke Spanish at home in 2021, according to Statista data drawn from the American Community Survey.
Geographic concentration is heavy in the Southwest, California, Florida, and Texas, but the Spanish-speaking population is no longer confined to those corridors. Census trends consistently show Spanish-speaker growth across the Midwest and Mountain West states, reshaping communities that once had little linguistic diversity.
Pew Research Center data shows that more than 2.8 million non-Hispanic Americans also speak Spanish at home, a figure that underlines how far the language has spread beyond its immigrant origins.
The Next Tier: Chinese, Tagalog, Vietnamese, and Arabic
After Spanish, the drop in speaker numbers is steep, but the next four languages each represent millions of people and distinct communities with deep roots in American life.
- Chinese (Mandarin and Cantonese): With an estimated 3.5 million speakers, Chinese is the third most spoken language in the country, representing a 290 percent increase since the 1980s. Mandarin has become the dominant variety as immigration from mainland China has grown, though Cantonese retains strong community presence in California and New York, where Chinese immigration stretches back to the Gold Rush era.
- Tagalog: Approximately 1.7 million people speak Tagalog at home, according to Census Bureau data. Filipino immigration to the United States began in the early 20th century, and the community is now one of the oldest and largest Asian ethnic groups in the country. California and Hawaii are the primary hubs, though significant communities exist in Nevada and Washington state.
- Vietnamese: Vietnamese has seen the most dramatic proportional growth of any major language in the United States since 1980, increasing by more than 500 percent. An estimated 1.5 million people speak it at home, concentrated primarily in California, Texas, and the greater Houston and Orange County metro areas.
- Arabic: More than 1.4 million people speak Arabic in the U.S. as of 2023, a figure that has grown by more than 580 percent since 1980, according to Pew Research Center. Arabic-speaking communities are particularly established in Michigan, with Dearborn serving as one of the most significant Arab-American cultural centers in the country. Arabic also presents unique practical challenges for communication because of its right-to-left script and the significant differences between spoken dialects and written Modern Standard Arabic.
What Is the Third Most Spoken Language in Your State?
English is first in every state. Spanish is second in every state. But the third most spoken language varies considerably, and the pattern reflects wave after wave of immigration history. The following table draws on U.S. Census Bureau data and a 2024 analysis by Start.io of 94.7 million mobile devices in the United States.
| Language | States Where It Ranks #3 |
| Russian | Alaska, Colorado, Idaho, Illinois, Minnesota, Missouri, Montana, Nebraska, North Carolina, North Dakota, Washington |
| Persian (Farsi) | Delaware, Kansas, New Jersey, Oregon, Rhode Island, South Dakota, Texas, Virginia, Wisconsin, Wyoming |
| Portuguese | Connecticut, Florida, Louisiana, Maine, Massachusetts, New Hampshire, Pennsylvania, South Carolina, Utah, Vermont |
| Chinese | Arkansas, California, Mississippi, Nevada, New Mexico, New York, Oklahoma, West Virginia |
| Arabic | Arizona, Iowa, Kentucky, Michigan, Tennessee |
| Korean | Alabama, Georgia, Hawaii, Maryland |
| French | Indiana, Ohio |
A few data points from this table stand out. Russian appearing as the third language across eleven states reflects substantial post-Soviet immigration concentrated in urban centers like Chicago, Minneapolis, and Seattle, as well as more recent arrivals.
Portuguese showing up across ten states, including Massachusetts and Connecticut, traces back to 19th-century immigration tied to the whaling and fishing industries in New England. Massachusetts has nearly ten times the national average of Portuguese speakers per capita, according to the Start.io analysis.
Persian appearing in ten states is perhaps the least expected result. The Iranian diaspora in the United States is substantial and highly educated, with heavy concentrations in Northern Virginia, New Jersey, Texas, and California. Kansas, perhaps surprisingly, has 5.1 times the national average concentration of Persian speakers.
The Fastest-Growing Languages: What the Map Will Look Like Next
The rankings described above capture the current state, but language populations shift constantly. Several languages are growing fast enough to reshape the picture within a decade.
- Telugu has been identified by multiple Census analyses as among the fastest-growing languages in the country, driven almost entirely by tech-sector immigration from the Indian states of Andhra Pradesh and Telangana. More than 515,000 Telugu speakers live in the U.S. as of 2023, a figure that has grown by approximately 115,000 since 2018. States like New Jersey, Virginia, California, and Washington host the largest communities.
- Arabic is growing both through immigration from the Middle East and North Africa and through increased interest in the language among non-native learners tied to economic and geopolitical engagement with Arab-majority countries.
- Ukrainian have entered the conversation as a consequence of the ongoing conflict in Ukraine. According to a 2024 United Nations report, more than 6 million Ukrainians have been displaced. That has contributed to an increase of roughly 150,000 Ukrainian speakers in the United States, bringing the total to approximately 485,000 in 2023.
Languages moving in the opposite direction include Italian, German, Greek, and Polish. These were among the most common non-English languages in the mid-20th century, carried by massive waves of European immigration. As those communities assimilate across generations and new immigration from those countries remains modest, speaker numbers are declining steadily.
Why This Matters Beyond the Data
The linguistic map of the United States has real-world consequences that go beyond demographics. Federal civil rights law requires agencies receiving federal funding to provide meaningful language access to people with limited English proficiency. Hospitals are expected to translate vital documents into the most common languages in their service areas. Schools are required to provide ESL support. Courts must offer interpreter services.
For businesses, the stakes are different but equally concrete. More than 25 million Americans with limited English proficiency represent an enormous consumer base that is frequently underserved. Reaching these communities requires more than a basic translation. Regional dialects, cultural context, and document formatting conventions vary significantly across languages, as anyone who has tried to adapt a form or a website for Arabic speakers can confirm.
Organizations that need to communicate accurately across these communities rely on Elmura’s professional translation and localization services, which cover the full range of languages spoken across American communities, from the major tier of Spanish and Chinese to fast-growing languages like Telugu and Ukrainian.
A Language Map That Keeps Moving
America’s linguistic diversity is not a recent development. It reflects centuries of migration, displacement, and cultural exchange. What has changed is the scale and the pace. The Census Bureau’s tracking of language use, from its first systematic data collection in 1980 through the most recent American Community Survey cycles, shows a country that is becoming more multilingual, not less, even as each new generation of immigrants tends toward greater English proficiency over time.
The languages people speak at home tell a story about where they came from, what communities sustain them, and how American culture continues to evolve from the bottom up. That story is worth understanding, especially for anyone whose work requires actually reaching people where they are.
