ABD is right that it is too complicated to compare as they have done. The cost ratio depends on how much of the broadband is DSL and how much cable. The former is usually much cheaper. Then again are they using the single fee structure for these items or do they consider the combo price when TV and phone are included.
And the geographic dispersion of the population has a great influence on how much of the population is using broadband vs dialup. The larger the country the more difficult and expensive to provide broadband though the concentration of population in specific areas helps.
Of course government and commercial input and regulations affect price and distribution.
Too many variables to make simple comparisons.
