The numbers on e-waste per region but adjusted for population (very rough, with rounding errors):
Region % Pop Adj
---------------------------
Oceania 0.7 0.038 18.4
Europe 12.3 0.741 16.6
Americas 11.3 1.001 11.3
Asia 18.2 4.436 4.1
Africa 2.2 1.216 1.8
Would have been more interesting with the Americas split too.
