U.S. Data

U.S. Data

More than 43 million people living in the United States—whether as naturalized citizen, legal permanent resident, temporary resident, or unauthorized immigrant—were born in another country, representing 13 percent of the U.S. population. Immigration has ebbed and flowed throughout U.S. history, peaking at nearly 15 percent of the population in 1890 and plummeting to 5 percent in 1970. The data-rich research offered here traces the U.S. immigrant population by size, educational and workforce characteristics, English language proficiency, and more.

For information on U.S. immigrants by state, check out the State Immigration Data Profiles tool. And for detailed profiles on unauthorized immigrants nationally and by state, visit this tool.
