While most of these new arrivals are immigrants new to the country, some are naturalized citizens, lawful permanent residents, and others who might have lived in the United States for some time prior to returning in 2015.
The Census Bureau defines recent immigrants as foreign-born individuals who resided abroad one year prior to the survey, including naturalized citizens, lawful permanent residents, and others who might have lived in the United States for some time prior to 2015; as well as temporary nonimmigrants and unauthorized immigrants. This population includes naturalized citizens, lawful permanent residents, refugees and asylees, persons on certain temporary visas, and the unauthorized. That year, there were 2.2 million immigrants in the United States, representing nearly 10 percent of the population.
The concept of race as used by the Census Bureau reflects the race or races with which individuals most closely self-identify. In 2015, approximately 51 percent of immigrants were female.
