FYI
According to Wikipedia the percentage of English speakers located in the US is lower that 20%. Does this mean that only 1 in 5 users is from the US?
Population of the US: 334.914.895, Population of Europe: 745.173.774. 334.914.895/745.173.774 = 0,449%
English Speakers in the US: 297.400.000. English Speakers in Europe: 260.000.000. So you have about 37,4M more English speakers in the US than in Europe.
