In the first half of the 21st century, it is clear that racism and prejudice are prevalent worldwide and begin in childhood—as children can be perpetrators, victims, and bystanders of racism and prejudice. Reducing racism in youth is a critical step toward improving the society we all live in. This special issue reviews and synthesizes the latest research on racism and prejudice in childhood and adolescence, examining the role of families, schools, media, and friendships in reducing prejudice in youth and highlighting how to enhance collective well-being. By focusing on research over the past two decades, and including a range of international perspectives, this special section helps make theoretical, conceptual, and methodological advances on the topic of reducing and protecting children from racism.

在 21 世纪上半叶，很明显，种族主义和偏见在世界范围内普遍存在，并且始于童年——因为儿童可能成为种族主义和偏见的肇事者、受害者和旁观者。减少青少年的种族主义是改善我们所生活的社会的关键一步。本期特刊回顾并综合了关于儿童和青春期种族主义和偏见的最新研究，考察了家庭、学校、媒体和友谊在减少偏见方面的作用并强调如何提高集体福祉。通过关注过去 20 年的研究，并纳入一系列国际视角，本专题有助于在减少和保护儿童免受种族主义侵害的主题上取得理论、概念和方法上的进步。
