Says 585 in US, and 31 in Sweden
31 : 10m = 3.1 per million
585: 330m = 1.77
The "twice as many" ratio is approximately correct, but my raw numbers of 14 and 7 per million were off (assuming the wikipedia data is correct). Thank you for challenging them for me.
Germany 114 : 83m = 1.37
Hong Kong 67 : 7m = 9.57!!
Canada 39 : 37m = 1.05
Japan 33 : 136m = 0.24 (surprising)
Taiwan 31 : 23m = 1.35
Singapore 21 : 5.6m = 3.75
Indonesia 20 : 246m = 0.08 (ouch... but better than zero)
