Data Analysis · World Happiness Report 2015–2019
Five years of data across 155+ countries reveals the surprising — and not-so-surprising — drivers of national wellbeing.
Section 01
Average happiness scores across all surveyed countries, 2015–2019. Despite dramatic global events during this period, aggregate wellbeing proved remarkably stable — rising just 0.031 points (less than 1%) over five years. Hover over the chart to explore each year's figure.

Section 03
Six factors were compared against happiness scores using Pearson correlation. GDP per capita (r = 0.79) and life expectancy (r = 0.74) lead by a wide margin. Generosity, surprisingly, has almost no predictive power (r = 0.14). Switch the scatter plot between GDP and Freedom to compare relationships.

Section 04
GDP is the strongest single predictor of happiness (r = 0.79) — but the relationship is more nuanced than it first appears. Wealth doesn't make citizens feel rich. It funds the infrastructure of wellbeing: universal healthcare, social safety nets, low corruption, and the freedom to live as you choose. Three patterns in the data tell this story clearly.

Finland isn't the wealthiest country — the US, Qatar, and Singapore all have higher GDPs. What it has is how that wealth is spent: universal healthcare, free university education, high social trust, and consistent anti-corruption. GDP enables the environment; the environment creates happiness.
Qatar has the highest GDP per capita in the 2019 dataset — yet ranks 29th in happiness. Low social freedom scores, limited generosity (0.08), and concentrated wealth mean that economic power doesn't translate into broad-based wellbeing. Money alone is not enough.
Costa Rica's GDP is lower than Russia's, lower than China's. Yet it ranks 12th in the world for happiness — beating the United States. In 1948 it abolished its military entirely, redirecting that budget permanently into healthcare and education.

Using a multiple linear regression model trained on all 782 observations, adjust the six sliders to match your country's profile and see where it would rank. Sliders default to the 2019 world average.

r = 0.79Wealth and health predict happiness most strongly
GDP per capita (r = 0.79) and life expectancy (r = 0.74) are the two strongest correlates of national happiness — by a clear margin. Social support (r = 0.65) comes third. Generosity has almost no predictive power.
Finding 02
+0.031Global happiness has barely moved in five years
The worldwide average rose just 0.031 points from 2015 to 2019 — less than 1%. There was a small dip in 2017, followed by a recovery to the highest recorded average (5.407) in 2019.
Finding 03
2 / 10Being rich does not mean being happy
Only 2 of the 10 wealthiest countries appear in the top 10 happiest each year — Norway and Switzerland. Qatar, Kuwait, and the UAE rank among the world's richest but consistently miss the happiness top 10.
Finding 04
Rank 9.0Australia & New Zealand lead by region
Australia and New Zealand averaged rank 9.0 across 2015–2016 (the years with regional data), followed by North America (9.8) and Western Europe (29.4). Sub-Saharan Africa ranked last at 128.8.
