Prior studies point to individual characteristics, structural opportunities for contact, and classroom contexts as potential predictors of ethnic homophily. This study examines whether ethnic homophily is associated with the ethnic and socioemotional composition of the classroom among adolescents in the Czech Republic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Our data was collected in the autumn of 2023 from 6,447 students (\n                      <jats:italic>M<\/jats:italic>\n                      <jats:sub>age<\/jats:sub>\n                      = 15.6, SD\n                      <jats:sub>age<\/jats:sub>\n                      \u2009=\u20090.73) in 258 classrooms. We estimated ethnic homophily applying exponential random graph models (ERGMs), accounting for reciprocity, transitivity, and homophily in gender and popularity. Meta\u2010regression was then used to examine the classroom\u2010level correlates of the ethnic homophily coefficients calculated by the ERGMs.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The ERGMs provide evidence of ethnic homophily across all groups, with stronger effects observed among minority than majority students. For the Czech majority, homophily was positively associated with the proportion of Ukrainian students and negatively with the proportion of the \u201cother ethnicity\u201d group. Among Ukrainian students, homophily was positively associated with the proportion of Czech students. Neither in\u2010group size nor the socio\u2010emotional composition of the classroom, measured as classroom averages of empathic concern and perspective\u2010taking, was associated with ethnic homophily.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings underline the importance of structural factors, the size of relevant out\u2010groups, in understanding ethnic homophily.
