Immigrants as a percentage of population in NJ in 2017

The proportion of New Jerseyans who are immigrants inched closer to one quarter of the population in 2017, according to the latest data from the U.S. Census Bureau’s American Community Survey. An estimated 1.14 million people living in New Jersey last year were born elsewhere. Of those immigrants, 55.3 percent became naturalized citizens.

New Jersey’s immigrant percentage and population of naturalized citizens both were higher than for the United States as a whole: An estimated 13.7 percent of the nation’s more than 325 million residents were immigrants. Slightly less than half of them had become citizens as of last year.

The concentration of the foreign-born within the state varies widely. Less than 4 percent of the population in Cape May County were immigrants, compared with almost 44 percent of those in Hudson County. Bergen County had the greatest number of those born outside the U.S., about 184,000. Immigrants were most likely to become citizens in Gloucester County, where 73 percent of the foreign-born had been naturalized.
