This is slightly under 10 percent, about the same as at the October quantum gravity conference Loops '05. Although the two conferences were organized by different people around different topics, with only partial overlap, it is interesting that the US participation was about the same at each. At Loops '05 there were 156 registered participants, of whom about 7 percent were from the USA.
