Margin: An edge, border, boundary, or brink. In everyday use, marginalization defines the processes by which groups are excluded from the majority opinion or viewpoint (see also Hegemony in SDUK10). As Mostafa Henaway writes, marginalized social groups and individuals are disproportionately subject to labour exploitation; they are also under-represented in media and archives (see Afful, Peterson and Gerber. For a perspective on margins in economics, see Cochrane in SDUK06.
