Crunching the Numbers on Mortality
View the high resolution version of today’s graphic by clicking here.
One of the key traits that make human beings unique on planet Earth is that we’re aware of our own mortality.
Scientific advances have given us insight into which behaviors may prolong life, and which activities carry the greatest risk of death. Naturally, there have been some unique attempts to create a unified structure around risk and benefit, and to quantify every aspect of the human lifespan.
As today’s graphic from TitleMax demonstrates, even when we’re thinking about death, the human desire to codify the world around us is alive and well.
Certain events – such as a parachute failing to open or being hit by a meteor – have an easily quantifiable effect on life, but how do we measure the riskiness of day-to-day habits and situations? This is where a unique unit of measurement, micromorts, comes into play.
This concept, invented by renowned decision analyst Ronald A. Howard, helps compare any number of potentially lethal risks. One micromort equals a one in a million chance of sudden death. Here’s the riskiness of various activities measured in micromorts:
|Ascending Mount Everest||37,932|
|Getting out of bed (Age 90)||463|
|Being born (first day of life)||430|
|Riding a motorcycle||10|
|Running a marathon||7|
|Travelling 6,000 miles by train||1|
|Travelling 230 miles by car||1|
The average person, by the time they reach adulthood, will live approximately one million half-hours. Those 30 minute units are known as microlives.
The microlife concept was invented by professor David Spiegelhalter as a way to measure the consequences of various behaviors. For example, 20 minutes of physical activity earns us two microlives, while watching TV for two hours subtracts one microlife.
This measurement extends beyond nutrition and eating habits. Simply living in a modern era earns us an additional 15 microlives per day compared to those who lived a century earlier.
Casting the die on how we’ll die
How will the estimated 353,000 humans that will be born today eventually meet their end? This was the thought experiment conducted by Reddit user, Presneeze.
While our focus is often drawn to people who meet their end in spectacular and tragic ways, the vast majority of humanity will succumb to conditions such as heart disease and cancer.
Geography can play a big role in shifting these odds:
- In the United States, which is grappling with an opioid addiction crisis, there is a 1-in-96 chance of dying from a drug overdose.
- Diarrheal diseases may not be on the radar of most people living in first world countries, but in developing regions, they remain a leading cause of preventable death – particularly for children.
- In Russia, the odds are 1-in-4 that a man will not live beyond 55 years. The main culprit? Vodka.
On a long enough time line, the survival rate for everyone drops to zero.
Mapped: Visualizing the True Size of Africa
Common map projections warp our view of the globe. This graphic reveals the true size of Africa, which could fit the U.S., China, India, and more.
Mapped: The True Size of Africa
Take a look at any map, and it’s clear that the African continent is a big place.
However, despite the common perception that Africa is a large landmass, it’s still one that is vastly underestimated by most casual map viewers.
The reason for this is that the familiar Mercator map projection tends to distort our geographical view of the world in a crucial way — one that often leads to misconceptions about the relative sizes of both countries and continents.
A Geographical Jigsaw
Today’s infographic comes from Kai Krause and it shows the true size of Africa, as revealed by the borders of the countries that can fit within the continent’s shape.
The African continent has a land area of 30.37 million sq km (11.7 million sq mi) — enough to fit in the U.S., China, India, Japan, Mexico, and many European nations, combined.
|Country||Land Area (sq. km)||Land Area (sq. mi)||% of Africa|
|Total||30.33 million sq. km||11.71 million sq. mi||99.9%|
|🇺🇸 United States||9.83 million||3.80 million||32.4%|
|🇨🇳 China||9.60 million||3.71 million||31.6%|
|🇮🇳 India||3.29 million||1.27 million||10.8%|
|🇲🇽 Mexico||1.96 million||0.76 million||6.5%|
|🇵🇪 Peru||1.29 million||0.50 million||4.2%|
|🇫🇷 France||0.64 million||0.25 million||2.1%|
|🇪🇸 Spain||0.51 million||0.20 million||1.7%|
|🇵🇬 Papua New Guinea||0.46 million||0.18 million||1.5%|
|🇸🇪 Sweden||0.45 million||0.17 million||1.5%|
|🇯🇵 Japan||0.38 million||0.15 million||1.3%|
|🇩🇪 Germany||0.36 million||0.14 million||1.2%|
|🇳🇴 Norway||0.32 million||0.13 million||1.1%|
|🇮🇹 Italy||0.30 million||0.12 million||1.0%|
|🇳🇿 New Zealand||0.27 million||0.10 million||0.9%|
|🇬🇧 United Kingdom||0.24 million||0.09 million||0.8%|
|🇳🇵 Nepal||0.15 million||0.06 million||0.5%|
|🇧🇩 Bangladesh||0.15 million||0.06 million||0.5%|
|🇬🇷 Greece||0.13 million||0.05 million||0.4%|
You could add together all of the landmasses above and they would not equate to the geographical footprint of Africa, which itself is home to 54 countries and 1.2 billion people.
Editor’s note: The above table is slightly different from the countries shown in the visualization, which focuses more on fitting recognizable country shapes into the geographical shape of Africa.
Why the Misconception?
Interestingly, the problem with maps is not that Africa is sized incorrectly.
Using the animation below, you’ll see that Africa is actually the most accurately sized continent using the common Mercator map projection:
The Mercator projection attempts to place the spherical shape of the world onto a cylinder, causing areas closest to the poles to be “stretched”.
Africa, which straddles the Equator, barely changes in size — meanwhile, the countries furthest from the Equator become inflated from their true sizes on this type of map.
For those of us living in Western countries, this is an interesting dilemma to consider.
This means that the sizes of European and North American countries are distorted, giving us an inaccurate mental “measuring stick” for judging the relative sizes of other countries.
This has implications not only for Africa, but for the whole Southern Hemisphere: South America, India, the Middle East, and even Australia are “bigger” than they may initially appear on a map.
Ranked: The 100 Most Spoken Languages Around the World
This detailed visualization breaks down the 100 most spoken languages around the world, by total and native speakers. Can you find yours on the list?
Ranked: The 100 Most Spoken Languages Worldwide
Even though you’re reading this article in English, there’s a good chance it might not be your mother tongue. Of the billion-strong English speakers in the world, only 33% consider it their native language.
The popularity of a language depends greatly on utility and geographic location. Additionally, how we measure the spread of world languages can vary greatly depending on whether you look at total speakers or native speakers.
Today’s detailed visualization from WordTips illustrates the 100 most spoken languages in the world, the number of native speakers for each language, and the origin tree that each language has branched out from.
How Do You Define A Language?
The data comes from the 22nd edition of Ethnologue, a database covering a majority of the world’s population, detailing approximately 7,111 living languages in existence today.
The definitions of languages are often dynamic, blurring the lines around a singular understanding of what makes a language:
- Linguistic: focused on lexical and grammatical differences, or on variations within speech communities
- Social: focused on cultural or political factors, as well as heritage and identity
For the purposes of measurement, the researchers use the ISO 693-3 set of criteria, which accounts for related varieties and dialects—ensuring that linguistics are not the only factor considered in this count of languages.
Here are the language origins of the 100 most spoken languages:
Indo-European languages have the widest spread worldwide. According to Ethnologue, the language family contains over 3 billion speakers in total. Interestingly, there are actually 1,526 Niger-Congo languages altogether, though only 12 are represented here.
Let’s now dive into the top 10 most spoken languages overall.
Which Languages Have the Most Speakers?
It comes as no surprise that English reigns supreme, with over 1.1 billion total speakers—or roughly 15% of the global population. Mandarin Chinese, Hindi, Spanish, and French round out the top five.
|Rank||Language||Total Speakers||Language Origin|
|2||Mandarin Chinese||1,117 million||Sino-Tibetan|
|6||Standard Arabic||274 million||Afro-Asiatic|
However, this is only one piece in the full fabric of languages.
The metrics for native speakers tell a slightly different tale, as Mandarin Chinese shoots up to 918 million—almost 2.5x that of English native speakers.
|Rank||Language||Native Speakers||Language Origin|
|1||Mandarin Chinese||918 million||Sino-Tibetan|
|9||Western Punjabi||93 million||Indo-European|
Note: No native speaker data was available for Filipino, Standard Arabic, Nigerian Pidgin, or Cameroonian Pidgin.
Here, Spanish comes in strong second for native speakers with 460 million, considering it’s well-used across Latin America. The Indian languages of Hindi and Bengali cap off the top five by native speakers as well.
These are the biggest languages people learn growing up, but what about the ones they pick up later in life?
What About Second (L2) Languages?
Nearly 43% of the world’s population is bilingual, with the ability to switch between two languages with ease.
From the data, second language (L2) speakers can be calculated by looking at the difference between native and total speakers, as a proportion of the total. For example, 66% of English speakers learned it as a second language.
Swahili surprisingly has the highest ratio of L2 speakers to total speakers—although it only has 16 million native speakers, this shoots up to 98 million total speakers. Overall, 82% of Swahili speakers know it as a second language.
Swahili is listed as a national or official language in several African countries: Tanzania, Kenya, Uganda, and the Democratic Republic of Congo. It’s likely that the movement of people from rural areas into big cities in search of better economic opportunities, is what’s boosting the adoption of Swahili as a second language.
Indonesian is another similar example. With a 78% proportion of L2 speakers compared to total speakers, this variation on the Malay language has been used as the lingua franca across the islands for a long time. In contrast, only 17% of Mandarin speakers know it as a second language, perhaps because it is one of the most challenging languages to learn.
Keeping Language Traditions Alive
Languages are fluid, and constantly evolving—altogether, the 100 most spoken languages paint a unique picture across centuries of a changing world. Here’s the full list of these languages, by types of speakers and language origin.
|Rank||Language||Total Speakers||Native Speakers||Origin|
|26||Egyptian Spoken Arabic||65M||65M||Afro-Asiatic|
|33||Southern Min Chinese||50M||50M||Sino-Tibetan|
|45||Moroccan Spoken Arabic||33M||27M||Afro-Asiatic|
|48||Algerian Spoken Arabic||32M||29M||Afro-Asiatic|
|49||Sudanese Spoken Arabic||32M||32M||Afro-Asiatic|
|56||North Levantine Spoken Arabic||25M||25M||Afro-Asiatic|
|61||Sa'idi Spoken Arabic||22M||22M||Afro-Asiatic|
|74||Mesopotamian Spoken Arabic||16M||16M||Afro-Asiatic|
|78||Hijazi Spoken Arabic||15M||15M||Afro-Asiatic|
|98||South Levantine Spoken Arabic||12M||12M||Afro-Asiatic|
|99||Tunisian Spoken Arabic||12M||12M||Afro-Asiatic|
|100||Sanaani Spoken Arabic||11M||11M||Afro-Asiatic|
One reason these languages are popular is that they are actively and consistently used. Unfortunately, nearly 3,000 (about 40%) of all languages are at risk of being lost, or are already in the process of dying out today.
Languages play a crucial role in our daily lives. … [Their] losses have huge negative impacts indigenous peoples’ most basic human rights.
—UN, IYoIL statement
As a result, the United Nations declared 2019 the International Year of Indigenous Languages (IYoIL), with a resolution to continue fostering these languages and pass on their knowledge for future generations.
