Note. Model 1 uses a binary ‘immigrant’/’U.S.-born’ variable. Model 2 includes a deconstructed immigration variable broken down by age of immigration, including US Born as a ‘non-immigrant’ group within the immigration age variable. The reference group for both models is the theoretically least acculturated group (“immigrants” in Model 1’ “Immigrant 21+” in Model 2.”).
