This book discusses the issues of inequality and marginalization in India. The first section of the book contextualizes sociological traditions for the scrutiny of subaltern discourse on discrimination.  The chapters in the section explore self-identity, 'margins' in sociological traditions, subalternity and exclusion, citizenship issues of de-notified tribes, the role of religion for scheduled tribe Dalits and Ambedkar's ideas on tribes. The second section deals with the political economy of higher education, health and employment. The efforts of BR Ambedkar and the consequences of those efforts, his critique of education policies during British time and its alteration for independent India have been meticulously dealt with. The third section illustrates an application of theoretical understanding through narratives of labour bondage in Varanasi, sanitation workers in Mumbai and rickshaw pullers in Delhi. The last section establishes that unequal access to resources is a consequence of discrimination and marginalization induced by social identities. The book argues for equitable access to resources and opportunities to ensure health equity. The audience for this publication includes academics, researchers, health professionals, policymakers engaged with discrimination, exclusion, marginalization and inequity in health.
