The central European country topped the pool, which was based on global perceptions including the potential to drive trade, travel infrastructure and investment into the country.
Canada took second place, swiftly followed by Germany, the United Kingdom, Japan, Sweden and Australia.
The rankings were determined by scoring each country on 65 different attributes, which were put into nine thematic subrankings including Adventure, Citizenship, Cultural Influence, Entrepreneurship, Heritage and Quality of Life.
They explained: "The study and model used to score and rank countries were developed by Y&R's BAV Group and The Wharton School of the University of Pennsylvania, specifically professor David J. Reibstein, in consultation with U.S. News & World Report. A set of 65 country attributes - terms that can be used to describe a country and that are also relevant to the success of a modern nation - were identified. Attributes by nation were presented in a survey of more than 21,000 people from across the globe. Participants assessed how closely they associated an attribute with a nation.
"Each country was scored on each of the 65 country attributes based on a collection of individual survey responses. The more a country was perceived to exemplify a certain characteristic in relation to the average, the higher that country's attribute score and vice versa. These scores were normalized to account for outliers and transformed into a scale that could be compared across the board. Attributes were grouped into nine subrankings that rolled into the Best Countries ranking: Adventure, Citizenship, Cultural Influence, Entrepreneurship, Heritage, Movers, Open for Business, Power and Quality of Life."
