How the ranking is made

The World Happiness Report (WHR) has appeared since 2012, first edited by the economists John Helliwell, Richard Layard and Jeffrey Sachs. It is now published by the University of Oxford's Wellbeing Research Centre with Gallup and a UN network.

Its country ranking rests on one survey question from the Gallup World Poll. Respondents imagine a ladder whose top step, 10, is the best possible life for them and whose

bottom step, 0, is the worst, and say which step they stand on now. This is the Cantril ladder, after the American social scientist Hadley Cantril, who used it in his 1965 study The Pattern of Human Concerns. Gallup interviews about 1,000 people a year in each country, and the ranking uses a three-year average (2023 to 2025 in the 2026 edition), because a larger sample gives a more precise estimate.

How the ranking is made

Even so, each average has a margin of error, so every country gets a range of ranks too.

The report then tries to explain the differences with six national variables: GDP per capita, social support (having relatives or friends to count on in trouble), healthy life expectancy, freedom to make life choices, generosity (giving to charity, adjusted for income) and perceived corruption in government

and business. Together they account for more than three-quarters of the variation between countries and years. But they do not produce the scores. In the 2026 report's words: "Many people mistakenly believe that we use the six explanatory factors ... to craft our rankings. We do not."

The 2026 table

Task Check the chart against your guesses from "Make your guesses". Then answer questions 1–4 together, and for question 5 agree the two most important things the chart cannot tell you.

1. Which of your guesses was furthest out? What do you think misled you?

2. Iceland and Denmark are 0.001 apart. What do the rank ranges in brackets tell you that the ranks do not?

3. The United States and the United Kingdom are six places and 0.122 points apart. Is that a real difference?

4. A headline says: "Finns are the most cheerful people on Earth." What does it get wrong?

5. What does the chart hide? Name two things you would want to know before trusting it.

Six ingredients

Task Alone, rank the six variables from 1 (adds most) to 6 (adds least) to Finland's score of 7.764. Then agree a pair ranking, and give a reason for your 1 and your 6. Last: would your order change for the gap between Finland and Afghanistan?

A

GDP per capita

B

Social support

C

Healthy life expectancy

D

Freedom to make life choices

How to read it. Each piece shows how much a variable is calculated to add to the score compared with Dystopia, an imaginary country with the world's lowest national value on all six (its predicted score is 1.16). The last piece is Dystopia plus the country's residual, the part the six leave unexplained. The pieces are associations, not proven causes: the report notes that happier people may also live longer and trust more.

Why the Nordics? A 2020 WHR chapter by Frank Martela, Bent Greve, Bo Rothstein and Juho Saari pointed to well-run institutions, reliable welfare benefits, low corruption, personal freedom and social trust, and found little support for small populations, ethnic homogeneity or the weather.

READING

One question, many cultures

Critics raise three kinds of doubt about the ranking.

The first is the single question. A whole life becomes one number, and the wording shapes what people think about. In a 2024 study in Scientific Reports, August Nilsson and colleagues asked 1,581 adults in the UK to describe in words what the ladder's anchors meant to them. The ladder's wording drew more thoughts about power and wealth than about relationships, and an anchor about harmony reduced those thoughts the most.

The second is cultural response style. In some cultures people may avoid the ends of a scale or treat open contentment as boastful; in others, answering positively may be a social habit. If so, a score partly measures how people answer, not how their lives go.

A 2015 OECD study by Carrie Exton, Conal Smith and Damien Vandendriessche estimated that culture accounts for about a fifth of the country differences that living conditions leave unexplained. And when WHR 2018 ranked native-born and foreign-born residents separately, the two rankings were essentially the same.

The third is what the ladder measures. It asks for a life evaluation, a judgement about life as a whole, not a report of feelings. The WHR also asks about yesterday's emotions, and in the 2026 edition the top ten countries for positive emotions include six from Latin America and only one from Western Europe. "The happiest country" depends on which happiness you mean.

Which happiness?

Other measures ask different questions. Since April 2011 the UK's Office for National Statistics (ONS) has asked four in its Annual Population Survey, each answered from 0 to 10: how satisfied are you with your life nowadays; to what extent do you feel the things you do in your life are worthwhile; how happy did you feel yesterday; and how anxious did you feel yesterday.

Experience-based measures ask about moments rather than lives. In the Day Reconstruction Method (Daniel Kahneman and colleagues, 2004, tested on 909 employed women in Texas), people rebuild the previous day episode by episode and rate how they felt in each. In experience sampling, a phone prompts people at random moments; Matthew Killingsworth and Daniel Gilbert used it with 2,250 adults in 2010.

Task For each measure, say P (Pleasure), D (Desire) or F (Flourishing): which of the three answers is it closest to?

1. The Cantril ladder

2. ONS: satisfied with your life nowadays

3. ONS: the things you do are worthwhile

4. ONS: happy yesterday

5. ONS: anxious yesterday

6. The Day Reconstruction Method

7. Gallup: did you feel enjoyment during a lot of the day yesterday?

Which happiness?

Pleasure

Desire

Flourishing

How does your life feel?

Are you getting what you want?

Is your life going well?

hedonism

desire theories

objective-list theories

The Easterlin paradox

In 1974 Richard Easterlin, often called the first economist to study happiness data, published "Does Economic Growth Improve the Human Lot?". Within a country at one time, he found, richer people reported being happier on average. But in the United States from the 1940s to 1970, average happiness did not rise although income per head grew a great deal. This is the Easterlin paradox. His explanation was social comparison: people judge their income against a norm set by those around them, and when everyone gets richer, the norm rises too.

In 2008 Betsey Stevenson and Justin Wolfers replied in Brookings Papers on Economic Activity.

READING · CONTINUED

The Easterlin paradox

With data from far more countries, they found a clear link between average well-being and GDP per capita, with no point at which richer countries stopped gaining. Measured against the logarithm of income, so that a 10% rise counts the same for rich and poor, the slope was similar between countries, within countries and over time. Reanalysing older data, they argued that happiness had in fact risen in Japan and Europe, although the flat US trend remained a puzzle.

Easterlin was not persuaded. In a

2010 study of 37 countries followed for 12 to 34 years, he and colleagues found that happiness and income move together through booms and recessions but that their long-term trends are unrelated. In China, consumption per head rose fourfold between 1990 and 2010 with no matching rise in life satisfaction. Writing with Kelsey O'Connor in 2022, he argued that his critics' series, often about ten years long, were too short and confused short-term swings with long-term trends.

Finding 1: M (mixed). Stevenson and Wolfers (2008) found the income slope similar across countries, within them and over time, and argued that happiness rose with growth in Japan and Europe. Easterlin and colleagues (2010), following 37 countries for 12 to 34 years, found no long-run link, and China's fourfold rise in consumption from 1990 to 2010 brought no matching rise. Serious researchers using serious data still disagree.

Finding 2: W (weak). Wording and culture do shape answers at the margin (Nilsson and colleagues, 2024). But Exton, Smith and Vandendriessche (2015) put culture at about a fifth of the differences that living conditions leave unexplained, and WHR 2018 found that native-born and foreign-born residents produced essentially the same ranking. Living conditions, not answering styles, do most of the work.

Should we rank happiness?

Task Groups of 3 or 4. Discuss at least three of the questions. Then agree one change you would ask the report's editors to make, and why.

1. Should governments set targets for average life evaluation, as they do for inflation?

2. Would a minister for wellbeing where you live be useful, or a gimmick?

3. Is one 0–10 question enough to compare 147 very different countries?

4. If people adapt to hard conditions, can a happiness survey ever reveal injustice?

5. Do "happiest country" rankings help or harm the countries at the bottom?

6. Should a country's happiness score count more than its GDP when judging governments?

Private reflection

Task Choose one prompt and write privately. Nobody will read what you write. Sharing afterwards is optional.

Prompt 1

Think of someone you know (no names) who would probably place their life high on the ladder but often seems anxious or low from day to day, or the other way round. Which of the three answers best explains the gap?

Prompt 2 (lighter)

If your city could ask its residents one wellbeing question every year, which question would you choose, and what would you hope it showed?

Before Lesson 6

This week, find one claim that a country, city or group is "happier" than another. What exactly was measured?

Pleasure

It can be a news story, an advert, a travel article or a social media post. Note which question was asked, of whom, and which of the three answers it really speaks to.

Desire

Flourishing

Next lesson: Money and Happiness. Does more money make a person happier, and if so, how much more, and spent on what?

THE 2026 TABLE

1 Open. Common surprises: Costa Rica 4th (the highest rank ever for a Latin American country), Mexico 12th, and India 116th.

2 Iceland, Denmark and Costa Rica all have the range 2–4: the data cannot tell them apart. Only Finland is in "a group of one" (1–1), and Afghanistan (147–147) is clearly last.

3 Probably not. The United States' range (12–30) and the United Kingdom's (19–42) overlap heavily. The report notes that the top twenty countries are spread over less than one point, so small changes in an average can move a country many places.

4 The ladder measures a life evaluation, not cheerfulness or emotion. In the 2026 report the top ten for positive emotions include six Latin American countries and only one from Western Europe.

5 Any well-argued pair, for example: differences within a country (Afghan women's average is 1.26, below the national 1.446); who is asked (about 1,000 people a year, aged 15 and over); emotions as opposed to evaluations; trends over time; which countries the chart left out; and the six variables, which the bars do not show.

SIX INGREDIENTS the report's breakdown for Finland, WHR 2026

A (GDP per capita, 1.915), B (social support, 1.638), D (freedom, 1.105), C (healthy life expectancy, 0.939), F (perceived corruption, 0.491), E (generosity, 0.093). The averages across all 147 countries fall in the same order. For the gap between Finland and Afghanistan (6.318 points), the order changes: B (1.638), D (1.105), A (0.994), C (0.763), F (0.360), E (0.014), with 1.443 unexplained.

WHICH HAPPINESS? suggested; 1, 2 and 3 are there to be argued over

1 D. A judgement of one's life against the best possible life for oneself; closer to Desire than to feelings.

2 D, mostly. Satisfaction compares life with what one wants; some will argue it has a little Flourishing in it.

3 F, usually. "Worthwhile" asks whether life has meaning and purpose, the territory of Flourishing. Some will say it is still the person's own judgement, which pulls it towards Desire.

4 P. A feeling, and only yesterday's.

5 P. Also a feeling: the negative side of Pleasure.

6 P. It rates how each episode of a day felt.

7 P. An emotion during the day.
