Mapped: Global Happiness Levels in 2021
Mapped: Global Happiness Levels in 2021
“Are you happy?” is a deceptively complex question to both ask and answer.
It’s generally understood that having enough money to cover your needs and wants can help you live a relatively happy, comfortable life—and recent research shows this relationship may increase linearly as income levels grow, as well.
However, there’s much more to it than that. Happiness levels depend not just on financial security, but also broader perceptions of one’s social support, personal freedom, and more.
This series of map pulls data from the World Happiness Report to uncover the average scores of 149 countries between 2018-2020, and which ones emerged the happiest or unhappiest. We also look at the most and least improved countries in every region.
How is Happiness Measured?
First, let’s look at the factors used to calculate world happiness levels. Some clear indicators are health and wealth, both metrics that have been steadily on the rise worldwide. The report takes these into account, weighting GDP per capita and life expectancy at birth into the scores.
The report also looks at more intangible aspects, collecting survey responses around:
- Social support
- Freedom to make life choices
- Generosity
- Perceptions of government/ business corruption
- Positive or negative affects (Recent experience of emotions)
This year, there was a natural focus on the negative affect measure of the COVID-19 pandemic on happiness levels, such as exacerbating mental health risks. In addition, such measurements varied depending on each country’s response to the crisis.
Looking Closely at Regional Happiness Levels
Worldwide happiness comes in at an average score of 5.5, a marginal improvement since our previous coverage of this report in 2019. Let’s dive into regional outlooks for happiness levels.
North America
Current Mood: Happy (6.1)
Canada retains its spot as the happiest country in North America, although its overall global ranking has dropped over the years. In 2019, it was ranked in ninth place globally, dropping to 11th in the 2020 edition, and declining further to 14th place in this year’s report.
Haiti continues to fare poorly as the unhappiest in the region, with an average annual GDP growth of only 1.3% over 20 years. Its weak economy and political instability have been worsened by the pandemic—setting back efforts to reduce poverty and widening inequality.
South America
Current Mood: Content (5.9)
With the largest middle class in the Americas—60% of its population—and a miniscule 0.1% extreme poverty rate, Uruguay is the happiest South American country. The nation has also achieved equitable access to basic services, from education to electricity.
The trio of Colombia, Ecuador, and Venezuela are experiencing different stages of progress in happiness levels, but their relationship is very much interdependent.
Venezuela and Ecuador face similar economic challenges and sharp declines in oil prices. Venezuela is additionally acutely affected by socio-political unrest, triggering a mass exodus of citizens to Ecuador and Colombia alike. The silver lining is that the influx of highly-educated Venezuelan migrants may provide a 2% boost to Ecuador’s GDP.
Colombia, the most improved country, has halved its poverty rate in the last decade. In addition, it has welcomed almost 2 million Venezuelan migrants as of Dec 2020—and plans to provide them up to 10 years of protective status.
Europe
Current Mood: Happy (6.4)
Finland remains at the top of the leaderboard as the world’s happiest country. This year’s ranking was also influenced by high levels of trust in the way the COVID-19 pandemic was handled.
Meanwhile, the shock of the COVID-19 crisis is expected to be short-lived in Croatia, which is the most improved country. This is partly due to its steady pre-pandemic economic gains, although risks remain.
In the unhappiest country of Ukraine, conflicts continue to cause stress on its politics, security, and economy. In particular, government corruption remains a big public issue.
Middle East and Central Asia
Current Mood: It’s Complicated (5.3)
Saudi Arabia is the most improved country in the region, as it continues to reduce its oil dependence, diversify its economy, and bolster its public services. It has also been making some progress towards gender equality.
The tourism and hospitality industries contribute nearly 20% of Jordan’s GDP—and COVID-19 has caused a prolonged economic decline in the country along with the headwinds of these industries.
Although Afghanistan has seen improvements in access to basic services and its agricultural economy, challenges remain with prolonged conflict and violence. A post-pandemic recovery in the world’s unhappiest country might take several years.
East Asia and Oceania
Current Mood: Neutral (5.5)
Both New Zealand and Taiwan saw a successful COVID-19 response and recovery boosting their positions in the global happiness rankings. In fact, New Zealand was the only non-European country to make it into the top 10 on the global happiness list.
Note: As the report only covers 149 countries, “Oceania” only refers to Australia and New Zealand in this instance.
Although India remains the unhappiest country in the region, it also showed the most improvement overall, possibly due to its increased access to basic services. Notably though, the pandemic caused a sharp economic contraction in real GDP by 23.9% year-over-year in Q1’2021.
Africa
Current Mood: Unhappy (4.5)
In July 2020, the island nation of Mauritius joined Seychelles to become the second high-income country in Africa, helping cement its status as the happiest in the region.
Zambia, the most improved African country, has one of the world’s youngest populations by median age—which presents long-term opportunities for labor force participation.
On the flip side, agriculturally-reliant Benin struggles with high poverty, with close to 40% of the population living below $1.90 per day.
Zimbabwe, the unhappiest country, has been through not just natural disasters but financial disasters too. It experienced hyperinflation of 786% in May 2020, accompanied by an equally sharp rise in food prices.
Although each country has been uniquely impacted by the pandemic, it’s clear that on the whole, happiness levels take into account so much more. How will future rankings look like in a post-pandemic world?

Visualizing Two Decades of Reported Hate Crimes in the U.S.
Hate crimes across the U.S. have been on the rise since 2014. Here’s a look at the most common types of offenses over the years.

Visualizing Two Decades of Reported Hate Crimes in the U.S.
Across the U.S., thousands of hate crimes are committed each year, with many different motivating biases.
In 2020 alone, more than 10,000 unique hate crime incidents were reported to the Federal Bureau of Investigation (FBI)—and it’s likely that thousands more were committed that didn’t get reported to law enforcement.
What are the most commonly reported motivating biases, and how have hate crime rates evolved over the years? This graphic uses data from the FBI to visualize two decades of reported hate crime incidents across America.
What is Considered a Hate Crime?
Before diving in, it’s important to determine what constitutes a hate crime.
According to the U.S. Department of Justice, a hate crime is a crime that’s “committed on the basis of the victim’s perceived or actual race, color, religion, national origin, sexual orientation, gender, gender identity, or disability.”
These types of crimes are a threat to society, as they have a broader impact on communities than other types of crimes do. This is because hate crimes can foster fear and intimidate large groups of people or marginalized communities, making them feel unwelcome, unsafe, or othered.
Hate Crimes on the Rise
Hate crimes have been rising across the U.S. in nearly every year since 2014. By 2020, reported crimes across America reached record-level highs not seen in over two decades.
Year | Number of Reported Incidents | % Change (y-o-y) |
---|---|---|
2001 | 9730 | 18.4% |
2002 | 7485 | -23.1% |
2003 | 7545 | 0.8% |
2004 | 7685 | 1.9% |
2005 | 7411 | -3.6% |
2006 | 7715 | 4.1% |
2007 | 7625 | -1.2% |
2008 | 8039 | 5.4% |
2009 | 6613 | -17.7% |
2010 | 6633 | 0.3% |
2011 | 6299 | -5.0% |
2012 | 6594 | 4.7% |
2013 | 6044 | -8.3% |
2014 | 5599 | -7.4% |
2015 | 5871 | 4.9% |
2016 | 6276 | 6.9% |
2017 | 7321 | 16.7% |
2018 | 7170 | -2.1% |
2019 | 7892 | 10.1% |
2020 | 10299 | 30.5% |
And sadly, these figures are likely a vast undercount. Law enforcement submit this data to the FBI of their own volition, and in 2020, thousands of agencies did not submit their crime statistics.
Race-Related Hate Crimes are Most Common
Historically, the most reported hate crimes in the U.S. are related to race. In 2020, about 66% of incidents were motivated by discrimination against the victim’s race or ethnicity.
Type of Bias | Total Number of Crimes (2020) | % of Total |
---|---|---|
Race/Ethnicity | 6793 | 66.0% |
Religion | 1626 | 15.8% |
Sexual Orientation | 1311 | 12.7% |
Other | 569 | 5.5% |
Total | 10299 | -- |
While race is the most commonly reported hate crime, incidents related to gender and gender identity are on the rise—in 2020, there was a 9% increase in gender-related incidents, and a 34% increase in gender identity-related incidents, compared to 2019 figures.

Visualizing the Relationship Between Cancer and Lifespan
New research links mutation rates and lifespan. We visualize the data supporting this new framework for understanding cancer.

A Newfound Link Between Cancer and Aging?
A new study in 2022 reveals a thought-provoking relationship between how long animals live and how quickly their genetic codes mutate.
Cancer is a product of time and mutations, and so researchers investigated its onset and impact within 16 unique mammals. A new perspective on DNA mutation broadens our understanding of aging and cancer development—and how we might be able to control it.
Mutations, Aging, and Cancer: A Primer
Cancer is the uncontrolled growth of cells. It is not a pathogen that infects the body, but a normal body process gone wrong.
Cells divide and multiply in our bodies all the time. Sometimes, during DNA replication, tiny mistakes (called mutations) appear randomly within the genetic code. Our bodies have mechanisms to correct these errors, and for much of our youth we remain strong and healthy as a result of these corrective measures.
However, these protections weaken as we age. Developing cancer becomes more likely as mutations slip past our defenses and continue to multiply. The longer we live, the more mutations we carry, and the likelihood of them manifesting into cancer increases.
A Biological Conundrum
Since mutations can occur randomly, biologists expect larger lifeforms (those with more cells) to have greater chances of developing cancer than smaller lifeforms.
Strangely, no association exists.
It is one of biology’s biggest mysteries as to why massive creatures like whales or elephants rarely seem to experience cancer. This is called Peto’s Paradox. Even stranger: some smaller creatures, like the naked mole rat, are completely resistant to cancer.
This phenomenon motivates researchers to look into the genetics of naked mole rats and whales. And while we’ve discovered that special genetic bonuses (like extra tumor-suppressing genes) benefit these creatures, a pattern for cancer rates across all other species is still poorly understood.
Cancer May Be Closely Associated with Lifespan
Researchers at the Wellcome Sanger Institute report the first study to look at how mutation rates compare with animal lifespans.
Mutation rates are simply the speed at which species beget mutations. Mammals with shorter lifespans have average mutation rates that are very fast. A mouse undergoes nearly 800 mutations in each of its four short years on Earth. Mammals with longer lifespans have average mutation rates that are much slower. In humans (average lifespan of roughly 84 years), it comes to fewer than 50 mutations per year.
The study also compares the number of mutations at time of death with other traits, like body mass and lifespan. For example, a giraffe has roughly 40,000 times more cells than a mouse. Or a human lives 90 times longer than a mouse. What surprised researchers was that the number of mutations at time of death differed only by a factor of three.
Such small differentiation suggests there may be a total number of mutations a species can collect before it dies. Since the mammals reached this number at different speeds, finding ways to control the rate of mutations may help stall cancer development, set back aging, and prolong life.
The Future of Cancer Research
The findings in this study ignite new questions for understanding cancer.
Confirming that mutation rate and lifespan are strongly correlated needs comparison to lifeforms beyond mammals, like fishes, birds, and even plants.
It will also be necessary to understand what factors control mutation rates. The answer to this likely lies within the complexities of DNA. Geneticists and oncologists are continuing to investigate genetic curiosities like tumor-suppressing genes and how they might impact mutation rates.
Aging is likely to be a confluence of many issues, like epigenetic changes or telomere shortening, but if mutations are involved then there may be hopes of slowing genetic damage—or even reversing it.
While just a first step, linking mutation rates to lifespan is a reframing of our understanding of cancer development, and it may open doors to new strategies and therapies for treating cancer or taming the number of health-related concerns that come with aging.
