13.7% of the United States population are foreign-born

The US Census Bureau's 2018 American Community Survey results show that 44.7 million people living in the United States were not born in the country and are not citizens.

The 2018 American Community Survey estimates released by the United States Census Bureau reveal that a record-breaking 44.7 million people are foreign-born. That's 13.7% of the United States population.

Records show that these figures are at their highest since 1910.

In the same survey, a subset of those foreign-born who are "not a US citizen," of which there were around 22 million, as of 2018.

These figures have also been released shortly after a heated political debate over whether the decennial Census survey should including a citizenship question.

While the citizenship question was rejected from the main Census the annual American Community Survey, compiled by the Census Bureau, does ask about a person’s place of birth, citizenship and year of entry into the U.S. The data is compiled to estimate the foreign-born U.S. population.

Historic records show that in 1960 and 1970, about one in 20 US residents were foreign-born. Today, that ratio is about one in seven and in America’s largest states - California, Texas, Florida and New York - more than 15% of residents are foreign-born.

Irish-born living in the United States

According to the 2016 American Community Survey 125,840 people living in the United States were born in Ireland.

A massive 32.3 million, or 10%, of the US population, claimed to have Irish ancestry. Amazingly this figure is seven times the actual population of the Republic of Ireland itself (4.6 million).

Overall in the United States Irish is the second-most frequently reported European ancestry, after German.
