It is seen that the developed countries US, Canada, N. Europe, Japan, Korea, Australia, Taiwan have a high NRI (> 5.13, dark green) NRI, followed by S. & E. Europe, New Zealand, Chile, Malaysia, Tunisia, Qatar (NRI > 4.13, light green). The worst off countries (< 3.13, grey) of the countries reported on (countries not reported are in white) are mainly land-locked countries.
There is a strong correlation "R (square)>0.6" between the TCP throughput and NRI. The TCP throughput is measured from the US, so we have not included countries near US (Canada, Mexico etc) as they are expected to have greater TCP throughput due to their proximity to the US. Africa is mostly at the bottom with NRI less than 3.3 and TCP throughput mostly less than 1000 Kb/sec. Europe and East Asia are mostly at the top. In South Asia (large orange squares) though India has the largest NRI it is between Pakistan and Sri Lanka in its TCP throughput.
