Does a City’s Population Size Impact its Quality of Life?
City living isn’t everyone’s cup of tea—the world’s most populous cities especially can be hectic, noisy, and busy.
Yet, despite the chaos of urban life, cities offer inhabitants a number of comforts and conveniences that are harder to find in smaller towns. That’s why more people are moving into urban areas around the world.
But do these conveniences reflect in people’s quality of lives?
According to research compiled by Elaine Siu, bigger doesn’t always mean better—at least when it comes to population size. This interactive visualization takes a deep dive into this dataset.
Measuring Quality of Life
Siu uses data from Numbeo’s 2022 Quality of Life Index to compare the quality of life in nearly 200 different cities around the world. For the purposes of this research, Siu used cities with metropolitan area populations of over 500,000.
The index measures quality of life using eight different metrics:
- Cost of Living
- Purchasing Power
- Property Price to Income Ratio
- Pollution
- Traffic Commute Time
- Safety
- Healthcare
- Climate
A majority of the metrics (six of the eight) seemed to correlate with population size, suggesting that the bigger a city’s population is, the lower its quality of life in those metrics.
Here’s a look at the full list of cities included in the study, along with their overall quality of life scores and their metro area populations:

It’s worth noting that the negative correlation between the quality of life and population size only appeared in cities above the median population of 2.4 million people, indicating that the size of a city doesn’t appear to impact quality of life until a certain tipping point. Then, above the median, there’s a blatant downward trend.
However, Tokyo is an anomaly—its quality of life is much higher than it’s metropolitan population would predict.
Zooming in on Tokyo
Despite being the world’s largest urban area, Tokyo compares favorably compared to other top megacities across the index. When ranked among the top five megacities, it places in first for Purchasing Power, Safety, Traffic Commute Time, Cost of Living, Healthcare, and Pollution.
What’s so special about Tokyo? One major thing going for the Japanese city is its immaculate public transport system. The city’s transport is so efficient, the city’s rail service once issued a public apology after a train left the station 25 seconds earlier than its scheduled departure.
Another factor that makes Tokyo so livable is its relatively affordable housing, at least compared to other big cities like New York and Hong Kong. This is partly because of the city’s flexible land zoning system, which makes it relatively easy for developers to build housing and mix-use communities.
As our world becomes increasingly more urbanized, and cities around the world continue to increase in size, will they be able to emulate Tokyo’s growth? And if not, what other city design trends and innovations can cities utilize to raise quality of live?

Top 20 Countries Where Older People Are the Happiest
Advanced economies are the happiest countries for older people, likely due to their stronger social security systems.
Top 20 Countries Where Older People Are the Happiest

The newest global happiness index doesn’t have any massive surprises from the ongoing trends of the last decade: Europe generally does the best, Africa is still finding its footing, and Asia and South America have vast rank disparities between constituent nations.
However, as the World Happiness Report notes, happiness levels differ across age groups, and countries’ overall ranks tend to obfuscate how the old and young feel separately. To counter this, the report also creates a happiness index by age.
We’ve visualized the top 20 happiest countries according to those aged above 60. For comparison, we have also included a country’s overall index rank.
Data and Takeaways
The top two countries where the seniors are most satisfied—Denmark and Finland—also happen to be the top two countries on the overall happiness index.
As a general trend, advanced economies make up the bulk of this top 20 list, likely due to their stronger social security systems and financial security. Relatedly, they also tend to do well when it comes to the best countries to retire in.
Country | Happiness Rank (Age 60+) | Overall Happiness Rank (All ages) | Rank Difference |
---|---|---|---|
🇩🇰 Denmark | 1 | 2 | -1 |
🇫🇮 Finland | 2 | 1 | +1 |
🇳🇴 Norway | 3 | 7 | -4 |
🇸🇪 Sweden | 4 | 4 | 0 |
🇮🇸 Iceland | 5 | 3 | +2 |
🇳🇿 New Zealand | 6 | 11 | -5 |
🇳🇱 Netherlands | 7 | 6 | +1 |
🇨🇦 Canada | 8 | 15 | -7 |
🇦🇺 Australia | 9 | 10 | -1 |
🇺🇸 U.S. | 10 | 23 | -13 |
🇦🇪 UAE | 11 | 22 | -11 |
🇱🇺 Luxembourg | 12 | 8 | +4 |
🇰🇼 Kuwait | 13 | 13 | 0 |
🇨🇭 Switzerland | 14 | 9 | +5 |

🇮🇪 Ireland | 16 | 17 | -1 |
🇨🇷 Costa Rica | 17 | 12 | +5 |
🇮🇱 Israel | 18 | 5 | +13 |
🇧🇪 Belgium | 19 | 16 | +3 |

Norway, at third, has the first real discrepancy, with its elderly population ranking four places higher compared to its overall 7th place rank.
New Zealand (6th) and Canada (8th) also have gaps with their overall ranks: indicating that the older generation is happier than other generations within the country.
But for the U.S., (10th) and the UAE (11th), this rank discrepancy is in the double-digits.
In fact, when ranking only by those aged below 30, the U.S. ranks outside of the top 50, indicating that its younger residents are significantly unhappier than their older counterparts.
This is an interesting phenomenon mirrored in Canada, Australia, and New Zealand. According to the report, as recently as a decade ago, the younger generation in these countries were about as happy as those aged over 60.
“In the West, the received wisdom was that the young are the happiest and that happiness thereafter declines until middle age, followed by substantial recovery.” –- World Happiness Report.
For other countries like Costa Rica (17) and Israel (18), this pattern reverses. Their overall rank is higher than their rank for older populations, indicating that the young are happier.
