Denmark has the happiest workers in the world, according to the latest Universum Global Workforce Happiness Index.

The study is the biggest of its kind, surveying over 200,000 professionals in 57 markets about the level of satisfaction in their current job, willingness to recommend their employer to others and likelihood of switching jobs in the near future.

The Nordic countries with the exception of Finland have the highest levels of satisfaction and the least inclination to switch employers.

“Employee happiness is crucial for retaining good talent as well as having a motivated workforce that delivers great results and continuously innovates,” said Daniel Eckert, the research project manager at Universum.

“If the young professionals in a market show low levels of discontent, that is a good sign for the economy as whole. However, it is at these times when it’s harder to obtain the best talent from your competitors.”

Denmark was followed by Norway, Costa Rica, Sweden and Austria in the rankings.

The UK ranked at number 32 and the US at 36.
