Background. Research has established the family as the predominant context for child labor practices. Decisions to involve children in child labor within the family or by a family member (herein family child labor) is strongly motivated by cultural beliefs that normalize child labor. This systematic review sought to synthesize evidence on the social norms that support child labor practices, and the normative interpretation of international child labor legislation/standards. Methods. We followed the PRISMA procedure for systematic review by reviewing empirical articles published between 2000 to 2021 and contained within the four key databases: Scopus, ISI Web of Sciences, PubMed and Embase. Findings from 13 articles that met the inclusion criteria were analyzed thematically. Results. The review included studies from three continents: Africa, Asia and Europe. Gender norms, informal apprenticeship norm, norms on succession and sustenance as well as obedience, were key social norms that influenced child labor practices in the family. Parents’ decision to involve children in child labor was strongly influenced by the collective acceptance of some occupations (e.g., cocoa farming and fishing) as family occupations, which need to be preserved, undertaken and passed on to children. Child rights and the UNCRC principle of children’s participation were considered foreign to most non-western countries and interpreted as contravention to the cherished social norm of obedience. The findings underlie the link between social norms and the common social values of resilience, hard work, and respect. Conclusion. The results provide foundations and target to develop normative change intervention programs to re-orient the negative interpretations of common social values and provide alternative pathways that prevent child labor within the social context.
