Nearly one in ten babies born in the United States in 2023 entered the world as the child of a mother who had no legal right to be here or was present only on a temporary visa. According to data analyzed by Pew Research Center, out of 3.6 million total births that year, some 320,000 were to unauthorized immigrant mothers or those here on short-term legal status. Of those, roughly 245,000 came from mothers who were in the country illegally with fathers who were neither citizens nor lawful permanent residents. Another 15,000 involved temporary-status mothers with similarly non-citizen fathers. The remaining 60,000 were born to illegal immigrant mothers paired with citizen or green-card fathers.
These figures represent the highest number of such births since 2010, arriving after years of porous borders and lax enforcement under the previous administration. The timing is no coincidence. Record illegal crossings and expansive use of temporary protections swelled the population of non-citizens inside the country, directly feeding higher birth totals among that group.
