The 1850 United States census was the first federal U.S. census to query respondents about their "nativity"—i.e, where they were born, whether in the United States or outside of it—and is thus the first point at which solid statistics become available. The following chart, based on statistics from the U.S. Census from 1850 on,[1] shows the numbers of non-native residents according to place of birth. Because an immigrant is counted in each census during his or her lifetime, the numbers reflect the cumulative population of living non-native residents.

The table below lists the estimated number of illegal immigrants for the top 10 countries with the largest estimated number by country of birth and year in the thousands. There is no national census done on the legality of being in the United States of those born abroad. No data is available for 2001-2004 and 2020 while for 2010, 2015 and 2018 this table has the revised number. Source: [3]
