Social background refers to the social, cultural, and economic conditions associated with an individual’s or group’s position within society and the resources, experiences, and relationships acquired through these conditions ^[1][2]. It commonly includes characteristics such as socioeconomic status, family educational and occupational background, cultural resources, social networks, and patterns of socialization that influence individuals’ opportunities, identities, and participation in social life ^[1][3]. Social background shapes the development of knowledge, values, behaviors, expectations, and cultural practices through interactions within families, communities, and institutions ^[2][4]. It also contributes to differences in access to educational opportunities, social resources, and forms of cultural participation by influencing the distribution of economic, social, and cultural capital ^[1][3]. In cultural and social studies, social background is understood as a contextual and relational condition that reflects how individuals are situated within broader social structures and cultural systems rather than as a fixed personal characteristic ^[2][4].
