For those who don't want to deal with a .xls spreadsheet, I grabbed it, added a couple helpful columns (accounts per request and requests per 100m population), took a screen capture, and uploaded the PNG to imgur.com.
The US has the most total requests, by far, but is only 5th when population is considered. Here are requests per 100m population:
11869 Hong Kong
8434 Taiwan
5234 Germany
4386 Italy
4030 United States
3273 Australia
2864 France
2853 Singapore
2761 United Kingdom
1584 Spain
457 Argentina
370 Ireland
209 New Zealand
158 Brazil
136 Mexico
123 India
86 Canada
