It is slightly strange to ask about England rather than the UK when referring to a country.
Here's a link to the actual poll details:

The only reason I can see for not including countries like Scotland, Eire, Australia or New Zealand is if they only included countries with a population over 20m, but I can't see why they would do that.
Australia's population is over 20m. Israel's is 7m and Cuba's 11m.
