Grey = no estimate. 49 of 56 states have 2023 data.

Source: Pew Research Center residual-method estimates (total foreign-born from Census surveys minus the legally present population), vintages 1990-2023; no direct count of unauthorized residents exists. Estimates are rounded (nearest 5,000) and carry published margins of error; there is no 2020 estimate (pandemic survey disruption)
