Adults in Denmark are the best non-native English speakers in the world, followed by those in the Netherlands and Sweden, as shown in the fourth edition of the EF English Proficiency Index (EF EPI), which looked at 750,000 adults across 63 countries.
North African and Middle Eastern adults find themselves towards the bottom of the ranking. Worldwide, most countries with strong English skills continue to improve, while countries with weaker English skills are often stagnating or declining.
