Overview

Sourcing

Our project examines the factors that influence happiness levels across countries by mainly using the 2020 World Happiness Report dataset. This dataset tracked the average Cantril Ladder Happiness Score across 153 countries, as well as tracked 6 explanatory numerical variables: logged GDP per capita, social support, healthy life expectancy, the freedom to make life choices, generosity, and perceptions of corruption. The dataset, what it includes, and its limitations are discussed in greater depth in the data tab, which contains our data critique.

In addition to our primary source of the 2020 World Happiness Report Dataset, we also utilized a wide range of secondary sources in the form of research papers from academic journals. We found these sources with the help of academic search engines, such as JSTOR and the UCLA Library Search. These sources helped us to not only explain what we saw in the data (for instance, why there is a general positive relationship between logged GDP per capita and happiness), but to also help explain what the dataset could not explain, such as how cultural factors like religion and language can effect ideas and feelings of happiness, as well as exploring other ways happiness has been measured (like Bhutan’s Gross National Happiness Index).

Processing

For our project, we accessed the 2020 World Happiness Report Dataset through Google Sheets, as it was provided through the Bruinlearn Site and downloaded it as a .csv file. Data cleaning was essentially little to none as the World Happiness Report 2020 dataset is already compiled from other datasets and was essentially completely clean as there were no missing or N/A values for the parts of the dataset we used for our narrative. Therefore, we were able to use the data as was to make visualizations and findings.

For our data visualizations, we heavily utilized Tableau, as its types of graphs included maps, bar charts, and scatterplots. Therefore, given it’s versatility and official endorsement in our class, we decided to utilize it for the data visualizations across our narrative. We were able to embed our Tableau Visualizations by publishing our charts to Tableau Public and pressing the share button, which provided the appropriate HTML code to input onto our Gitpages’ Github Repository.

Presentation

We decided to utilize Gitpages to host our project as it was a way to connect our class project to our already existing Github profiles, as well as the fact that Gitpages have better security and faster connections, ensuring that our website stays up and functioning. In addition to this, Gitpages also had numerous website templates through Jekyll sites, allowing us to utilize a premade template to create a visually appealing website. We utilized a green and white color combination for our website, as green is typically the color associated with calmness, happiness, and positivty, which seemed fitting given the narratives focus and content.

We shared our data visualizations on the website by publishing our data visualizations from Tableau onto Tableau public and pressing the share button to get HTML code that would embed it onto the website.

Finally, we also utilized a timeline in order to better present the history of how happiness has been measured and what factors people have thought influenced it. We utilized Timeline.js to create the timeline as it allowed us to effectively add text and images to enhance the timeline, as well as the fact that it was the timeline website our whole group was most experienced and comfortable in using.

Hi! I am a Data Science and Business Economics double major at UCLA, with a minor in Entrepreneurship. I got interested in this project because of what happens when you take something personal like well-being and turn it into one number that countries can be ranked with. My part of the site is about the countries the World Happiness Report gets wrong, meaning the ones that report way more or way less happiness than its six variables say they should. I did the outlier analysis and made the graph, and I brought in the sources on income, inequality, and life evaluation.

Research, Narrative & Data Visualization Specialist

Hi! I am a Statistics and Data Science student at UCLA. For this project, I worked on the written narrative, interactive timeline, and data visualizations. I also contributed to the data critique and annotated bibliography by examining the dataset’s limitations and researching the institutional, cultural, and linguistic factors that may influence happiness.
