We retrieved the dataset of the happiness score in 2015 to 2020 from [kaggle](kaggle.com) where the World Happiness Report post their dataset as [csv](https://www.kaggle.com/unsdsn/world-happiness?select=2019.csv). The data represents the happiness levels of 155 different countries from 2015 to 2020. There are six factors used to measure happiness in different countries, where you can see how it varies by region, GDP, social support, health expectancy, freedom, perception of corruption, and generosity. And the whole world is divided into 11 regions based on geographical location: Central and Eastern Europe, Commonwealth of Independent States, East Asia, Latin America and Caribbean, Middle East and North Africa, North America, Oceania, South Asia, Southeast Asia, Sub-Saharan Africa, Western Europe. For analysis question 4, we use the data of the Here we use the data of the Average Annual Hours Actually Worked per Worker in each country from the OECD stat. in each country from the [OECD stat](https://stats.oecd.org/Index.aspx?DataSetCode=ANHRS). `4c:T422,chart2 = { const isDark = options1.theme === "dark";

A happy life will make you full of energy rather than full of stress. So, what factors can affect happiness? From an individual perspective, it may be economic status, social status, etc. From the perspective of the country, is the national happiness index closely related to factors such as economic development, social welfare, and environmental quality? In 2011, the United Nation adopted a novel measure known as the gross national happiness (GNH) and invited its member nations to measure the level of subjective happiness of its citizens. Since the adoption of GNH, the Gallup World Poll began to collect happiness data starting from 2012 and continued to do so every year thereafter.
