About
The World Happiness Report by is
a yearly publication
by Gallup, the Oxford Wellbeing Research Centre,
the UN Sustainable Development Solutions
Network, and the WHR’s Editorial Board that records the "happiness scores"
per country
from information like GDP, social support, and life expectancy.
This project aims to show
how countries have changed in happiness, the happiest and least happy
regions over time,
and the factors that affect a country's happiness score.
The report is compiled based on surveys conducted among citizens of various
countries, assessing subjective well-being and factors contributing to happiness.
A factor's score
correlates to how much it contributes to a country's overall happiness score.
Happiness Scores Stay Stable, Even Through the Pandemic
Select a year using the dropdown menu.
Hover over a country to see its
score and ranking.
Countries not
colored do not have recorded data.
Scroll on the map to zoom in; double-click to reset the zoom and position.
Note: Antarctica is not pictured as it has no data.
Generally, Western European countries remain the happiest countries across
the years.
North American countries are on the higher end of happiness scales, but have been
steadily decreasing since 2015.
Countries in South Asia and Africa consistently remain on the lower
end of the scale.
Even comparing the scores before and after the pandemic, the overall scores per region stay relatively stable.
Nordic Countries Remain the Happiest
Select a year in the dropdown menu to see happiness rankings for that year.
Choose "Ascending" or "Descending" to see the top or bottom 15.
Hover over a country's bar to see its score.
Regardless of the year, European countries dominate the top 15.
Specifically, the Nordic countries (Denmark, Sweden, Finland, Iceland)
are consistently in the top
5 happiest every year. Comparing year by year, their happiness scores seem to increase steadily.
Israel is an outlier in that it is the only Middle East country that is always in the top 15 happiest.
African countries like Afghanistan, Burundi, and Togo are consistently at the bottom of the list.
The Americas/ANZ and Europe Dominate the Yearly Rankings
Hover over a dot to see the average happiness score.
Note: Commonwealth of Independent States was not recorded until 2017.
Despite the high percentage of European countries in the
top 15 by year, North America and Australia/New Zealand are consistently the most happy countries on
average.
However, as expected from the previous charts, West European countries are not far behind in average
scores.
The Middle East and African regions are also consistently at the bottom of the rankings.
It's also worth noting that after a jump in 2019, Middle East and North Africa fell to the 3rd lowest
spot and stayed there.
Social Support and Freedom are the Most Valued Factors
Hover over a country name to focus that country.
Click on a country name to remove/restore it.
Despite the variance in values, the patterns across different countries
remain relatively consistent.
Most of the top countries highly value social support, life expectancy, and freedom to make choices.
Countries with lower Log GDP per capita have higher perceptions of social support and subsequently
freedom to make life choices.
Again, as an outlier, Israel's happiness score mostly comes from its perceptions of social support and
life expectancy, as freedom, generosity, and trust are markedly low.
Luxembourg is another standout country as its GDP is the highest, but perceptions of social support and
generosity are among the lowest this year.
Methodology
Background and Motivation
I was personally very interested in which areas of the world are considered the happiest, and
I
felt that I and my audience (my peers) would benefit from
learning about different countries as we look to continue our lives and careers.
I was also excited at the idea of being able to visualize a decade's worth of data and being able to
compare data from over such a long period of time.
Data Processing
As previously stated, my data is from the World Happiness
Report, but the different datasets were compiled and
downloaded from Kaggle (except for
2024, which was directly from the WHR website).
From 10 different datasets, there were lots of inconsistencies in things like header names, country
names, and number formatting, so I
created several simple Python scripts and Excel to clean the
data and manually changed
country names where necessary.
Specifically, "Region" and "Rank" were not included in every set, so I had to add them myself.
I then used the Region to calculate the average happiness score for every year so I could visualize
and rank them.
