Global Happiness Insights: Key Drivers, Trends, and Regional Analysis

Happiness isn’t just about wealth — it’s about balance. Our analysis shows that while GDP strongly influences happiness, factors like family support,…

Average Happiness Scores vary significantly across regions. The analysis produced two visualizations — a horizontal bar chart and a box plot — showing how happiness is distributed across all regions. Australia and New Zealand top the rankings with an average score of 7.285, while Sub-Saharan Africa has the lowest average at 4.203 across 40 countries, representing a gap of 3.082 points between the happiest and least happy regions.

There is a strong positive relationship between GDP per Capita and Happiness Score across countries, with a Pearson correlation of r = 0.781. This means that wealthier nations tend to report significantly higher happiness levels. A scatter plot has been generated showing this relationship, with countries color-coded by region and a trend line illustrating the overall pattern.

The analysis identified countries that have strong Economy (GDP per Capita) or Health (Life Expectancy) metrics — ranking in the top 25% — yet still fall below the median Happiness Score. A scatter plot was generated showing Happiness vs. Economy for all countries, with underperformers highlighted in red with country labels. A data table was also produced listing these countries along with their Region, Happiness Score, Economy, and Health values.

Two interactive charts and a data table were generated to explore how Trust and Generosity vary by region and influence happiness. The grouped bar chart shows regional averages for both metrics, while the scatter plot maps Trust vs. Happiness scores sized by Generosity and colored by region. Trust has a moderate positive correlation with happiness (0.395), while Generosity has a weaker link (0.180). Australia and New Zealand top both categories, and Central & Eastern Europe shows the lowest trust scores. Western Europe, North America, and ANZ consistently lead in both trust and overall happiness.

Among the four factors analyzed, Economy (GDP per Capita) has the strongest correlation with Happiness Score (r = 0.781), followed closely by Family (r = 0.741) and Health (Life Expectancy) (r = 0.724). Freedom shows a moderate but still meaningful correlation (r = 0.568). Two visualizations were generated: a bar chart ranking all four factors by their correlation strength, and a scatter plot showing the relationship between Economy and Happiness Score across different world regions.

The analysis successfully identified the top 10 happiest countries in 2015 and visualized what drives their happiness scores. Two charts were generated: a stacked bar chart showing how different factors (Economy, Family, Health, Freedom, Trust, Generosity, and Dystopia Residual) contribute to each country's happiness score, and a horizontal bar chart ranking the top 10 countries by their overall happiness score. The data tables also provide a detailed breakdown of each country's scores across all contributing factors.

The analysis breaks down average happiness contributing factors across 10 regions. A data table has been generated showing how each factor — Economy (GDP per Capita), Family, Health (Life Expectancy), Freedom, Trust (Government Corruption), Generosity, and Dystopia Residual — contributes to overall happiness scores by region. Australia and New Zealand rank highest with a total average contribution of 7.29, while Sub-Saharan Africa ranks lowest at 4.20, highlighting significant regional disparities in happiness drivers.

The analysis successfully detected outlier countries in both Trust (Government Corruption) and Generosity columns using the Z-score method with a threshold of 2.5. A scatter plot was generated highlighting outlier countries in red with their names labeled, making it easy to spot which nations have unusually high or low scores. The tables provide detailed breakdowns of each outlier country along with their Region and Happiness Rank.

The Happiness Score across all 158 countries follows an approximately normal distribution. A histogram with a KDE curve has been generated, with green and blue vertical lines marking the mean (5.376) and median (5.232) respectively. The scores range broadly, and the IQR method found zero outliers, meaning all countries fall within the expected bounds.

The analysis produced two visualizations: a full correlation heatmap showing relationships between all happiness factors, and a horizontal bar chart ranking each factor's correlation with the overall Happiness Score. These charts reveal which factors most strongly predict happiness across countries.
