This paper examines the socio-economic transformation of women in Jamshedpur from 1907 to 2000, analysing their transition from domestic roles to participation in economic activities. Using historical and analytical methods, the study draws on archival records of Tata Steel, district gazetteers, census reports, and secondary literature. The findings show that industrialisation created new opportunities for women, but these were uneven and limited. In the colonial period (1907–1947), adivasi women known as rezas formed over 35% of the unskilled workforce and yet received the lowest wages, no housing, and no welfare protection. The wives of formal employees lived in better conditions but only as dependants welfare was given in the name of the male worker, not the woman herself. In the post-independence phase (1947–1980), Tata's expanding welfare model improved women's access to healthcare, schools, and community life, but always within a framework that treated women as mothers and wives, not as economic citizens. The third phase (1980–2000) saw the first generation of educated women entering formal employment as teachers, nurses, and clerks, while market women, self-help groups, and small enterprises began to change the economic landscape from below. Women’s participation increased mainly in informal and service sectors, while their presence in core industrial labour remained low. Corporate welfare policies improved health and education but also reflected a paternalistic approach that controlled women’s roles. The study argues that women’s empowerment in Jamshedpur was partial and shaped by class, community, and institutional structures. The article concludes that progress for women in Jamshedpur was real but deeply uneven good for those inside the welfare system, much slower for adivasi and peripheral community women. True economic participation only began to emerge in the final two decades of the century, and it was driven as much by women's own agency as by corporate welfare.
