Agriculture is among the top three industries in employing immigrants, according to data compiled by the Pew Research Center.
In 2014, 33% of the nearly 2 million agriculture workers in the U.S. were born outside the United States. Coming in at No. 1 was private households, with 45% of people working in private households being immigrants. Coming in second was textile, apparel and leather manufacturers, with 36% being immigrants.
These industries had the biggest share of workers, but they weren't the biggest overall employers. The biggest employer of lawful immigrants was retail and the top industry for unauthorized immigrant workers was construction.
Immigrants made up 17.1% of the total U.S. workforce in 2014, or about 27.6 million workers out of 161.4 million. About 19.6 million workers, or 12.1%, were in the U.S. legally; about 8 million, or 5% entered the country without legal permission or overstayed their visas.
