Visualizing the World’s Sleeping Habits
Sleep quality, patterns, and duration may vary among countries, but one thing’s clear─people still aren’t getting enough sleep. While some people can function on a few hours, others find themselves reaching for that second cup of morning coffee instead of getting those extra Z’s.
Today’s graphic comes from Raconteur and highlights some startling takeaways from the 2019 Philips Global Sleep Survey, answered by over 11,000 adults from 12 countries.
Let’s settle in to discover what impacts our sleeping habits, also known as sleep hygiene, and what helps people sleep better and longer.
Why Sleep Is Important
Roughly 62% of adults worldwide feel that they don’t sleep well when they go to bed. Losing just one or two hours of sleep per night can have the same impact on motor and cognitive functions as going without sleep for a full day or two.
Experts have long emphasized that developing good sleeping habits can help to maintain our physical, mental, and emotional well-being. Ongoing sleep deprivation can also cause severe, long-term health conditions:
- Heart disease and heart failure
- Weak immune system
- High blood pressure
- Kidney disease
Drowsiness has been a significant factor in roughly 100,000 car accidents every year, causing an estimated 1,500 deaths. Sleep deficiency has also been linked to a number of disasters, such as airplane and boat accidents, and even nuclear reactor meltdowns.
The Science of Sleep
The human body follows the circadian rhythm─a 24-hour repeating rhythm that operates as an internal clock. This clock is controlled by two things: external cues such as light and darkness, and internal compounds that trigger and maintain our sleep.
These chemicals work together to keep our sleep/wake cycles in harmony.
- Adenosine: slowly builds the desire for sleep throughout the day
- Melatonin: produces drowsy feelings that signal your body is now ready for sleep
- Cortisol: naturally triggers your body to wake up
While sleep duration can vary greatly around the world, most adults are still not getting enough shut-eye. The average person gets 6.8 hours of sleep on a weeknight, which is significantly lower than the recommended 8 hours.
One company in the UK has even developed a real-time map of social media posts from people who say they can’t fall or stay asleep.
What Prevents Better Sleep?
People can suffer from a lack of sleep for many reasons─below are the top six culprits.
- Worry and Stress
Job, family, health, financial, and a myriad of other concerns plague people from all walks of life. Adults living in Canada and Singapore tend to be the most worried.
The physical space where you sleep plays a large role in the quality and duration of your sleep. Nearly 35% of adults fall asleep somewhere other than their bed. Interestingly, Chinese adults are the least comfortable when sleeping, while Japanese adults are the most comfortable.
- Work and School Schedules
Hectic careers and heavy school workloads have a direct and lasting impact on sleeping habits. Many forego sleep in favor of completing work, social, and household responsibilities.
In the age of technology, natural rhythms of daytime and nighttime perception have been skewed, especially from the effects of blue light emitted from our device screens.
Eating food, or drinking alcohol or caffeine within the last few hours before bedtime can prevent our brains from knowing it’s time to wind down and get ready for sleep. Adults living in the fast-paced developed nations of China, Canada, the United States, and Singapore are the most caffeinated.
- Health Conditions
Over three-quarters of adults experience at least one health condition that impacts sleep. These include insomnia, sleep apnea─which affects roughly 22 million people in the U.S. alone─snoring, restless leg syndrome (RLS), narcolepsy, and chronic pain.
Developing Good Sleeping Habits
Sleep is often the first to be neglected with our hectic schedules. Here are a few ways to practice better habits for a good night’s sleep.
Wake up and go to bed at the same time each day─even on weekends─to establish a more ingrained rhythm for your body clock and help your brain better prepare for sleep.
Pick a time of day that suits your schedule and energy levels, and be sure to stick with it. Exercise helps to balance melatonin and cortisol levels throughout the day.
Get outside often during the day and reduce the time spent outside at night. Limit screen time at least 30-60 minutes before sleep.
Food and Drink
Avoid eating large meals or drinking alcohol or caffeine in the last couple of hours before you go to sleep. Caffeine effects can linger for up to 8 hours, which breaks natural sleep rhythms.
Recent studies have shown that mind-body treatments for insomnia such as yoga, tai chi, and meditation had positive impacts on improving sleep quality.
Set the bed for success—keep your room cool and dark, buy a high-quality mattress and comfortable bed linens and use a white-noise machine to help you fall asleep.
Sleep is one of the most important aspects of our health; it’s also one of the easiest to neglect. Don’t put yourself into sleep debt─get enough shut-eye to enjoy those sweet dreams.
Every Song With Over 1 Billion Spotify Streams
Spotify’s ‘Billions Club’ playlist tracks every song with over 1 billion streams. We took the data and broke it down by decade and artist.
Every Song With Over 1 Billion Spotify Streams
View the high-resolution of the infographic by clicking here.
Spotify has a relatively short history, launching in Europe in 2008, and eventually moving into the U.S. market in 2011. Since then, the Stockholm-based company has become the world’s most popular audio streaming service with 456 million users across 183 markets.
With such a large userbase, major artists on Spotify have seen their biggest hits accumulate millions, if not billions of streams. So, in July 2021, Spotify created the Billions Club, a playlist comprising every song to reach the 1 billion milestone.
We at Visual Capitalist saw this as an opportunity to create a unique data visualization, so we compiled the entire playlist and arranged it by decade and artist.
The Top 10 Artists
Below are the top 10 artists, ranked by their number of songs with over 1 billion streams. The list actually includes 11 artists because Shawn Mendes, Bruno Mars, and Coldplay are tied with 5 songs in the Billions Club.
|Rank||Artist||Artist's Monthly Listens||Songs With 1 Billion+ Streams|
Sorting this list in different ways can reveal some interesting takeaways.
For starters, Ariana Grande is the only female artist present in the top 10. Her best performing song on Spotify is 7 rings, which was included in her fifth studio album thank u, next. The track has accumulated 1.8 billion streams since February 8, 2019.
Female superstars who narrowly missed the top 10 list include Adele, Billie Eilish, Dua Lipa, and Olivia Rodrigo, who all have four songs in the Billions Club.
Most of these artists are relatively new, so it’s reasonable to assume that they’ll be breaking into the top 10 soon. Olivia Rodrigo, for example, just released her debut album SOUR in 2021.
By Artist Tenure
Which top 10 artist has been around the longest?
We measure tenure in this context as the time that has elapsed since the artist’s debut album. In this case, the crown goes to Eminem, who released Infinite in November 1996.
The 11-track album was released on cassette and vinyl, and according to the Eminem Fandom wiki, only sold around 1,000 copies. The title track, Infinite, is the only song from the album that is available on Spotify, and it currently has 33 million plays.
The Full List
The Billions Club contains over 300 songs, with the majority being released in the 2010s. This is largely due to the fact that Spotify launched at the start of that decade.
Below is the data we used to create this infographic, which can be sorted by track name, artist, play count, track length, or release date.

Note: Our list includes two songs that have crossed one billion streams, but have not yet been added to the official playlist.
Please note that new songs are constantly being added to the Billions Club, so our list may not be up to date for very long. Both Rihanna and Taylor Swift will be joining the club any day now as Umbrella (feat. Jay-Z) and Blank Space tick up towards the one billion mark.
With songs on this playlist receiving over 446 billion streams so far, at least some of them are likely to be familiar to you. Some may even find their way into your annual feature called Spotify Wrapped, a personalized roundup sent to Spotify users covering your most listened to songs of the year.
One Final Note
With the holidays upon us, you’re going to be hearing a lot of Christmas music in the coming weeks, whether it’s at home, at the mall, or in a cafe.
Chances are, one of those songs will be Mariah Carey’s All I Want for Christmas Is You. Not only is this song a holiday staple, it’s also the only Christmas song with over 1 billion streams on Spotify.
Released in October 1994 with Carey’s first holiday album, Merry Christmas, the track continues to be a massive success. In 2021, it became the first and only Christmas song to receive Diamond certification by the RIAA (Recording Industry Association of America).
3D Map: The World’s Largest Population Density Centers
What does population density look like on a global scale? These detailed 3D renders illustrate our biggest urban areas and highlight population trends.
A 3D Look at the Largest Population Density Centers
It can be difficult to comprehend the true sizes of megacities, or the global spread of 8 billion people, but this series of population density maps makes the picture abundantly clear.
Though they appear topographical and even resemble urban areas, the maps visualize population density in squares. The height of each bar represents the number of people living in that specific square, with the global map displaying 2km x 2km squares and subsequent maps displaying 1km x 1km squares.
Each region and country tells its own demographic story, but the largest population clusters are especially illuminating.
China vs U.S. — Clusters vs Sprawl
Click here to view the high resolution version.
Zooming into the most populated country in the world, China and its surrounding neighbors demonstrate massive clusters of urbanization.
Most people are familiar with the large density centers around Hong Kong, Guangzhou, and Shanghai, but the concentration in central China is surprising. The cities of Chengdu and Chonqing, in the Sichuan Basin, are part of a massive population center.
Interestingly, more than 93% of China’s population lives in the Eastern half of the country. It’s a similar story in neighboring South Korea and Taiwan, where the population is clustered along the west coasts.
Click here to view the high resolution version.
The U.S. also has large population clusters along the coasts, but far more sprawl compared to its Asian counterparts. Though the Boston-Washington corridor is home to over 50 million residents, major centers spread out the population across the South and the Midwest.
Clearly visible are clusters in Florida (and not exclusively focused around Miami like some might believe), Illinois, Georgia, and Texas. The population is sparse in the West as expected, but California’s Los Angeles and Bay Area metros make up for the discrepancy and are just behind New York City’s density spikes in height.
India & Southeast Asia — Massive Density in Tight Areas
Click here to view the high resolution version.
At 1.38 billion people, India’s population is just behind China’s in terms of size. However, this sizable population fits into an area just one-third of China’s total land area, with the above map demonstrating what the same amount of people looks like in a smaller region.
On one hand, you still have clear clusters, such as in Mumbai, New Delhi, Kolkata, and Bangladesh’s Dhaka. On the other, there is a finite amount of room for a massive amount of people, so those density “spikes” are more like density “peaks” with the entire country covered in high density bars.
However, we can still see geographic trends. India’s population is more densely focused in the North before fading into the Himalayas. Bangladesh is equally if not more densely populated, with the exception of the protected Sundarbans mangrove forest along the coast. And Pakistan’s population seen in the distance is clustered along the Indus River.
Click here to view the high resolution version.
Geographic constraints have always been the biggest deciding factor when it comes to population density, and nowhere is this more apparent than Southeast Asia.
Take Indonesia, the fourth largest country by population. Despite spanning across many islands, more than half of the country’s 269 million inhabitants are clustered on the single island of Java. The metros of Jakarta and Surabaya have experienced massive growth, but spreading that growth across oceans to entirely new islands (covered by rainforests) is a tall order.
When the distance is smaller, that cross-water growth is more likely to occur. Nearby in the Philippines, more than 100 million people have densely populated a series of islands no bigger than the state of Arizona.
Indeed, despite being one of the most populated areas in the world, each country in Southeast Asia has had its own growing problems. Some are limited by space (Singapore, Philippines), while others are limited by forests (Thailand, Vietnam).
A World of Different Density Pictures
Though the above maps cover the five most populated countries on Earth, accounting for nearly half of the world’s population, they only show a small part of the global picture.
As the full global density map at the top of the page highlights, the population patterns can accurately illustrate some geographic patterns and constraints, while others need further exploration.
For example, the map clearly gives an outline of Africa and the sparse area that makes up the Sahara Desert. At the same time, landmasses like Australia and New Zealand are almost invisible save for a few clusters along the coast.
