The happiest countries in the world rankings from 2005 to 2009, visited thousands of respondents from 155 countries and regions, and asked them to grade their life satisfaction from 1 to 10, and draw the happiness index of "life assessment".

A survey shows that the 4 Nordic countries headed by Denmark account for the top 4 in the "happiest countries and regions in the world", because the people in these countries live in plenty. China ranked 125 in the mainland, while Hongkong ranked 81.

Recently, the UN sustainable development solutions network (SDSN) recently released report shows that Norway in 2017 was rated the happiest country in the world, and the Central African Republic has become the world's most happy country. China ranked 79. The report shows that the top 10 most happiest countries in the world are Nordic countries.

Norway is one of the pioneers in the creation of a modern welfare state. The foundation of the welfare state is a set of economic systems aimed at ensuring social and economic security. Each citizen is a member of the state welfare and labor insurance organization, and enjoys a wide range of financial support, such as medical treatment, pension, and disability gold.

Why do people have such a sense of happiness? It is not only wealth, but also the positive and positive influence of people's way of life, the way and concept of educating their children, so that their nations and countries can maintain happiness for a long time.
