Between 2008 and 2018, southern states saw the fastest growth of Latinxs of any other U.S. region (Flores et al., "U.S. Hispanic population reached new high in 2018, but growth has slowed," 2019), transforming states in this region into what many researchers call "the Nuevo South." Drawing on literature that explores factors that influence ethnic identification, a dimension of ethnic identity development, among Latinx college students and results from survey research on ethnic identification of Latinx undergraduates in the Nuevo South, this article presents evidence of the effects of cocurricular experience, curricular experience, the sociopolitical context of the Nuevo South, and ethnicity on ethnic identification of undergraduate students who identify as Latinx and attend two higher education institutions in the Nuevo South. Results reveal that cocurricular experience, the sociopolitical context of the Nuevo South, and ethnicity are significant predictors of ethnic identification. At the same time, results suggest that curricular experience is not a significant predictor of ethnic identification. Results are discussed within the unique context of higher education institutions located in the Nuevo South. Implications and recommendations for research and practice are provided.
