How the origins of America's immigrants have changed since 1850

The United States has been a top destination for immigrants worldwide, with over 70 million immigrants arriving since 1965. In 2022, the immigrant population reached 46.1 million, constituting 13.8% of the total population. The largest groups of immigrants hail from Mexico and India. Over time, the origins of immigrants have shifted significantly. In 1920, Germany and Italy were the main sources, contrasting with the present diversity. Changes in U.S. immigration laws, such as the 1965 Immigration and Nationality Act, have influenced these shifts by opening up legal immigration from Asia and Latin America. Unauthorized immigration also played a role, with significant numbers arriving before 1982 and gaining legal status later. Further revisions to immigration laws in 1990 increased the diversity of immigrant origins. The immigrant population distribution across states has varied, with Mexican immigrants being the largest group in 29 states in 2022. These trends highlight the dynamic nature of immigration patterns in the U.S. over the years.
