Second, foreign-born residents in the United States U.S. are overwhelmingly nonwhite. Census data from 2016 indicate among the foreign-born population in the United States U.S.—totaling 43,681,654—7,895,629 people were “White Only” (18.1%). This means that the term foreign-born population in the United States U.S. refers to a group that is more than 80 eighty percent people of color. Support: Jynnah Radford & Abby Budiman, 2016, Foreign-Born Population in the United States Statistical Portrait PEW. RES. CTR. (Sept. 14, 2018). Census data from 2016 indicate among the foreign-born population in the U.S.—totaling 43,681,654—only 7,895,629 people were “White Only” (18.1%). The breakdown shows 19,595,412 “Hispanic”; 7,895,629 “White Alone, Not Hispanic”; 3,660,002 “Black Alone, Not Hispanic”; 11,569,405 “Asian Alone, Not Hispanic”; and 961,206 “Other, Not Hispanic.”
Third, racial gerrymandering that results from Republican map-drawing is common in the United States U.S., and usually packs Democrats into few districts to dilute their broader electoral influence.
