In its 2019 report, "Beyond the Border: Family Separation in the Trump Era," UnidosUS demonstrates how the current trajectory of the nation's immigration policies is threatening the future of an entire generation of American children. This issue brief on Illinois is part of a series that builds on this analysis by exploring the stakes at the state level if the immigration policy status quo prevails. It compiles available population estimates to sketch a portrait of children in Illinois's Latino immigrant families. For instance, while 97% of Latino children in Illinois are U.S. citizens, 55% of them have at least one immigrant parent. Furthermore, Illinois's Latino children are 25% of the state's youth and thus crucial to Illinois's future success across various measures. [For the full report, see ED603926.]
