Financial inclusion, the ability of households to access and use formal financial services, is a key determinant of economic development, yet a large share of India's population remained outside the formal banking system in the early 2000s. During this first decade of the 2000's, India underwent one of the fastest telecommunications expansions in the world, with mobile subscriptions rising from roughly 6.5 million in 2001 to nearly 900 million by 2011. This paper examines whether districts with greater baseline access to communication technologies in 2001 experienced larger subsequent gains in household banking access by 2011, using district-level data from the Census of India across the two waves. A difference-in-differences framework is used, interacting each district's 2001 level of television, radio, and telephone access with a post-period indicator, with district and year fixed effects and controls for literacy, urbanisation, and baseline banking access. Television and radio access are found to be positively and significantly associated with growth in household banking, and this relationship persists after the inclusion of controls. The relationship for telephone access is initially large but becomes statistically insignificant once baseline banking access is controlled for, suggesting that it largely reflects pre-existing differences in financial development rather than an independent informational effect. Split-sample estimates show larger effects in districts with lower initial access, a difference that is statistically significant for television and telephone but not for radio. Comparisons by literacy and urbanisation are descriptive rather than formally tested, but point to stronger television and telephone effects in more literate districts and stronger television and radio effects in more urbanised districts. These findings suggest that mass-media technologies functioned as an informational complement to conventional banking infrastructure during India's pre-digital-finance period, while the role of telephones, which in 2001 were mostly landlines, was more closely tied to broader socioeconomic development.
