GSD does sales stats for Europe. Don't ask me exactly what countries they gather sales data from, however.
GSD does EMEA (Europe, Middle East, Africa)

For digital data they say '
Great Britain', rather than the '
United Kingdom'. Which may mean they don't collect data from Northern Ireland or it may just mean they are one of many companies/people who don't understand the difference between Britain and the United Kingdom! So there is quite a disparity with their physical and digital number data coverage, e..g they only get digital data for Britain.
