This study aims to enhance our understanding of the diverse nature of social–emotional development and explore the demographic disparities and intersectionality of social determinants among children, with an emphasis on underserved populations of children in low-resource environments. Young children living in low-income families are exposed to a wide array of social and systemic risks that increase the propensity for poor learning and social–emotional development. Using data from the Head Start Family and Childhood Experiences Survey (FACES, this study focuses on the social–emotional development of a nationally representative sample of young children enrolled in the Head Start program (n = 1921, 50.18% male). Employing a person-centered approach, we assessed teacher-rated social–emotional competence, including approach to learning, social cooperation, aggression, hyperactivity, and anxiety/depression/withdrawal, to classify young children’s social–emotional development. This study identified four distinct social–emotional profiles—Adaptive, Average, Moderate Risk, and High Risk—through latent profile analysis. Furthermore, multinomial regression analysis revealed demographic disparities within each social–emotional profile, and significant intersectionality was found between race/ethnicity, age, and disability status in the social–emotional profiles. This research provides valuable insights for better supporting each child’s unique needs.

This study examined the diverse social-emotional development of a population-based cohort of 1,921 Head Start children, focusing on the variability in developmental patterns over time. We used data from the 2014 Family and Childhood Experiences Survey to conduct a latent profile analysis of teacher-rated social-emotional competencies, including children’s approaches to learning, classroom social cooperation, and behaviors such as aggression, hyperactivity, and anxiety/withdrawal. We identified four social-emotional profiles (i.e., Adaptive, Average, Moderate Risk, and High Risk) at two points (fall 2014 and spring 2015). Further, latent transition analysis revealed both stability and change within these profiles over time, with significant demographic differences in profile transitions. While some children in the Moderate Risk and High Risk profiles demonstrated persistent challenges, others showed improvement by transitioning to lower-risk profiles. These shifts highlight the potential for positive change, even among children facing significant early vulnerabilities. Gender differences were also evident, with boys more likely to follow trajectories reflecting higher behavioral and emotional challenges, indicating that gender might play a role in profile stability and change. These findings offer critical information into the dynamics of early social-emotional development of Head Start children, informing tailored interventions to address the social-emotional needs of young children from low socioeconomic backgrounds and mitigate negative transitions.
