This book offers a century-long analysis of gender inequality in South Asia, revealing how the persistent neglect of women’s education has shaped health, fertility, and labor outcomes. Utilizing census data from Pakistan, India, and Bangladesh (1931–2022), it quantifies the social and economic costs of excluding women from literacy and opportunity. Each chapter blends empirical data with historical reflection, tracing the consequences of unplanned lives, limited reproductive autonomy, and systemic healthcare disparities. Beyond statistics, the narrative also celebrates women’s resilience, highlighting individuals who catalyzed change in education, health, and labor despite patriarchal barriers. Combining rigorous analysis with human stories, this work reframes a hundred years of inequality, urging renewed investment in women as central to equitable development.
