Cost of 1gb of data in every country

I'd love to know a lot more details on how this was calculated.

I haven't seen anything below $10-20/GB for "actual committed data" depending on network for the US if you aren't willing to go all-in for years and submit to hard credit inquiries and associated bullshit that comes with it. Every company advertises "unlimited+++*" with insane amounts of gotchas. Ten tiers of unlimited, none of which are unlimited, all silently capped.

India - $0.09, Russian Federation - $0.52, UK - $1.39, USA - $8.00, Canada - $12.55. Even taking in to account the differences in terms of size, population densities, infrastructure etc the price differential seems to point to North Americans being price gouged, without lube
