While the U.S. immigrant population is diverse, just a few countries of origin make up a large share of the total. This pie chart series shows which countries had the largest immigrant populations at various time periods between 1960 and 2015 (use the slider to select different years). For countries not in the top ten, the immigrant population is aggregated in the "other countries" category. The growth of this category over time indicates that the immigrant population comes from increasingly diverse national origins.
1) The term "immigrants" (also known as the foreign born) refers to people residing in the United States who were not U.S. citizens at birth. This population includes naturalized citizens, lawful permanent residents (LPRs), certain legal nonimmigrants (e.g., persons on student or work visas), those admitted under refugee or asylee status, and persons illegally residing in the United States.
2) The figure for China excludes both Hong Kong and Taiwan (1990-2015).
