😀World Happiness Report Analysis (2015–2017)

Project Overview

This project explores global happiness trends using data from the World Happiness Report for the years 2015 to 2017. The analysis focuses on understanding how different factors such as economy, health, freedom, and family impact happiness rankings and scores across the globe. By leveraging interactive visualizations in Tableau, the project provides an engaging and insightful exploration of global well-being trends over three years. The aim is to uncover key patterns and regional differences while offering dynamic tools for users to interact with the data.

This study emphasizes the importance of socioeconomic, cultural, and institutional factors in shaping happiness levels. It also highlights disparities between regions and identifies consistent trends among high-performing and low-performing countries.

Key Objectives

• Analyze and visualize the happiness rank and score of countries globally from 2015 to 2017.

• Identify key contributors to happiness, such as Economy (GDP per Capita), Health (Life Expectancy), Freedom, and Family.

• Examine regional trends and year-over-year changes in happiness rankings and scores.

• Create a user-friendly Tableau dashboard with interactive features for deeper exploration of the dataset.

Features of the Tableau Dashboard

• Interactive Slicer: Users can filter countries based on happiness scores (2.9 to 7.5) for a focused analysis.

• Dynamic Visualizations:

  • Diverging green-blue color schemes visually highlight variations in happiness scores, with greener shades representing higher scores and blue shades representing lower scores.

  • Bubble and bar charts illustrate the impact of various factors on happiness scores.

• Time-Based Insights: Visualizations explore how happiness scores and rankings evolve over time.

Insights

Overall Trends

• Top Performers: Countries like Finland, Denmark, and Switzerland consistently scored above 7, reflecting strong economies, robust social support systems, and high life expectancy.

• Low Scorers: Countries such as Burundi, Central African Republic, and Tanzania recorded some of the lowest scores, highlighting economic and social challenges.

Regional Insights

• Scandinavian countries dominate the top happiness rankings, showcasing strong governance, social welfare, and trust in institutions.

• War-torn or economically challenged regions in Africa and the Middle East rank lower due to instability and lack of resources.

Factor-Specific Insights

Impact of Economy (GDP per Capita)

• Countries with higher GDP per capita generally score higher in happiness, emphasizing the role of economic stability.

Health (Life Expectancy) by Country

• Healthier populations tend to have higher happiness scores, highlighting the importance of accessible healthcare systems.

Impact of Freedom on Happiness Score

• Freedom to make life choices positively correlates with happiness scores, especially in Western and Scandinavian countries.

Family as a Key Contributor

• Strong family and social support systems are significant predictors of higher happiness levels.

Happiness Score by Region Over Time

1. • Happiness scores in regions like Sub-Saharan Africa show minimal variation, while regions like Europe display more pronounced trends over time.

Tools & Technologies

• Tableau: Used for creating interactive dashboards and visualizations.

• Dataset: World Happiness Report (2015–2017), which includes metrics such as happiness score, GDP per capita, social support, life expectancy, freedom, generosity, and perceptions of corruption.

• Analytical Techniques: Data cleaning, aggregation, and trend analysis.

Conclusion

This analysis offers a detailed exploration of the factors influencing happiness across countries and regions from 2015 to 2017. It provides a dynamic view of how different dimensions—economic prosperity, health, governance, and personal freedoms—shape happiness levels. The interactive Tableau dashboard empowers users to dive deep into the data, uncovering unique insights tailored to their interests.

Key takeaways:

• Economic and health factors are crucial drivers of happiness.

• Scandinavian countries consistently outperform others due to robust social and economic systems.

• The disparities in happiness scores emphasize the need for targeted interventions in low-scoring regions.

This project underscores the complexity of global happiness and the multifaceted nature of well-being, serving as a valuable resource for policymakers, researchers, and enthusiasts alike.
