This year, it shows that citizenship of a superpower doesn't carry the clout it once did. The United States, which ranked first in 2014 and 2015, has now dropped to fourth place. Immediately behind Germany, holding its position as runner-up for the second year running, is Sweden with visa-free access to 176 countries. Finland, France, Italy, Spain, and the United Kingdom -- which had topped the list since 2013 -- are now tied for third place, making Northern and Western European citizens the most privileged in international travel.
