How many new e-commerce users come online in India each year?

Population-segmented adoption model — broke India's population down by age band, urban/rural split, and smartphone + payment-rail penetration, then modeled the incremental adopters per band per year.

Landed close to the real figure after cross-checking against 2025 data (~342M).

Landed close to the real figure (~2,075) after re-deriving.
