The Definitive Answer: How Many Bilingual Speakers in the US?
The most direct answer is that approximately 67.8 million people in the United States speak a language other than English at home. This represents about 21.5% of the entire U.S. population aged five and older, making the country one of the most linguistically diverse nations in the world. This data comes directly from the U.S. Census Bureau’s American Community Survey (ACS), which is the most reliable source for this information.
It’s crucial to understand what this number represents. The ACS asks households if they speak a language other than English at home. This figure includes a wide spectrum of speakers, from fluent bilinguals who use both languages daily to individuals who may primarily use their heritage language with family. While it doesn’t measure fluency perfectly, it’s our best large-scale indicator of the prevalence of multilingualism in America.
The trend is undeniably upward. In 1980, this number was only around 23 million. The fact that it has nearly tripled in four decades highlights a significant demographic and cultural shift in the United States.
TL;DR: Key Statistics on Bilingualism in the US
- Total US Bilingual Speakers: Over 67.8 million people (21.5% of the population) speak a language other than English at home.
- Most Common Language: Spanish is by far the most spoken non-English language, with over 41 million speakers.
- Global Bilingual Speakers: Globally, it’s estimated that over 3 billion people (more than 43% of the world’s population) are bilingual.
- Key Trend: The number of bilingual individuals in the US has been increasing steadily for decades, driven by immigration and a growing value placed on multilingual skills.
- Top Bilingual States: California, Texas, New Mexico, Florida, and New Jersey have the highest concentrations of residents who speak a language other than English at home.
A State-by-State Breakdown of US Bilingual Speakers
The distribution of bilingual speakers in the US is not uniform; it’s heavily concentrated in certain states due to historical, cultural, and immigration patterns. When we analyze the data, a few states clearly stand out as hubs of linguistic diversity. From my experience analyzing demographic data, these concentrations create unique economic and social environments.
For instance, in states like California and Texas, bilingualism isn’t just a personal skill—it’s woven into the fabric of daily life, from business to public services.
Top 10 States by Percentage of Bilingual Speakers
The following table summarizes the states where speaking a second language is most common, based on the latest ACS data.
| State | % of Population (5+) Speaking a Language Other Than English at Home | Approx. Number of Speakers | Most Common Non-English Language |
|---|---|---|---|
| California | 44.1% | ~16.5 Million | Spanish |
| Texas | 35.5% | ~9.7 Million | Spanish |
| New Mexico | 33.1% | ~650,000 | Spanish |
| New Jersey | 31.7% | ~2.7 Million | Spanish |
| New York | 30.8% | ~5.8 Million | Spanish |
| Florida | 30.7% | ~6.3 Million | Spanish |
| Nevada | 30.5% | ~880,000 | Spanish |
| Arizona | 27.2% | ~1.9 Million | Spanish |
| Hawaii | 25.8% | ~340,000 | Tagalog / Ilocano |
| Massachusetts | 24.3% | ~1.6 Million | Spanish |
Regional Hubs and Emerging Trends
While the states above lead in percentages, it’s also important to recognize emerging trends. States like North Dakota, Delaware, and Utah have seen some of the fastest growth rates in their multilingual populations over the last decade. This is often tied to specific industries attracting a global workforce, such as tech in Utah or agriculture and energy in North Dakota.
In my work, I’ve seen how these demographic shifts directly impact local economies. Businesses in these growing regions are actively seeking bilingual talent to serve new communities, creating a feedback loop that further encourages linguistic diversity.
The Most Common Languages Spoken by Bilinguals in the US
While the U.S. is home to speakers of over 350 languages, a handful of them account for the vast majority of bilingual individuals. Spanish is, without a doubt, the dominant second language.
- Spanish: With approximately 41.8 million speakers, Spanish is the most common non-English language in the U.S. by a massive margin. Its prevalence is rooted in centuries of history in the Southwest and decades of immigration from Latin America.
- Chinese (including Mandarin & Cantonese): Roughly 3.5 million people speak a variety of Chinese. These communities are concentrated in major metropolitan areas, particularly in California and New York.
- Tagalog (including Filipino): Spoken by about 1.7 million people, Tagalog is the third most common language. Its speakers have a strong presence in states like California, Hawaii, and Nevada.
- Vietnamese: With 1.5 million speakers, Vietnamese communities have flourished, especially in Texas and California, since the 1970s.
- Arabic: Approximately 1.4 million speakers use Arabic at home. This population has grown significantly in recent decades, with large communities in Michigan, California, and New York.
- French: Including both standard French and Haitian Creole, there are about 1.2 million speakers. Louisiana has a historical French-speaking population, while Haitian Creole is prominent in Florida and the Northeast.
