Finland is once again the world's happiness nation.
The 2019 World Happiness Index, an annual ranking released by the Sustainable Development Solutions Network for the United Nations, placed the Nordic nation, which is known for its strong education system and public safety, at the top of the list for the second year in a row. Its neighbors Denmark, Norway, Iceland, and Sweden were all in the top 10, as well.
The ranking system considers six different factors — freedom, generosity, income, trust, healthy life expectancy, and social support — when determining nations' overall happiness levels.
The United States wound up as the 19th happiest country, down one spot from a year ago, and five spots from 2017, signaling that the nation is becoming less happy. Per U.S. News, the report specifies the decline of happiness among the American population lies parallel to a rise in depression, suicide ideation, and self-harm, as well as an "epidemic of addictions," including substance abuse, gambling, and poor diets.
