Finland is the world’s happiest country. The World Happiness Report, published Wednesday, studied the happiness levels of 156 countries. It considered factors such as life expectancy, social support and corruption in its examination. Finland pushed last year’s happiest country, Norway, to second place. The other three Nordic countries, Denmark, Sweden and Iceland also made the top ten. They are joined by Switzerland, The Netherlands, Canada, New Zealand, and Australia. The United States fell to 18th place. It came in 14th in the 2017 report. For the first time, the report also ranked 117 countries by the happiness and well-being of their foreign-born immigrants. Finland placed first in that group, as well. In fact, the study found that highly ranked countries in overall happiness had similarly happy immigrant populations.
