This study investigates the trends in spousal age differences in India from 1991 to 2011, analyzing socio-economic, educational, and cultural influences on marital age preferences. Data from the NSSO, Census of India, and NFHS indicate a decline in spousal age gaps until 2001, reflecting a shift towards egalitarian marital norms due to increased female education and empowerment. Post-2001, this trend plateaus or reverses, pointing to the persistence of traditional norms and emerging economic factors in marital decisions. The research highlights a correlation between economic affluence and larger spousal age gaps, varying regionally. Educational disparities, especially when husbands are more educated, result in larger age gaps, whereas equal educational levels correlate with narrower gaps. The findings suggest that economic and educational progress influences, but does not fully transform, traditional marital age norms, underscoring the need for continued focus on gender equality and educational empowerment.
