The Most Popular Wikipedia Pages, From 2007-2019
Where do you go to satisfy your curiosity about the world? Chances are, most people would turn to Google, where the first search result for virtually any topic is likely to be Wikipedia.
Wikipedia often acts as a quick-and-dirty first source of information—and today’s intriguing animation from Data Geek shows what people are reading about the most. The video highlights more than a decade of the most popular pages on Wikipedia, sorted by total monthly views.
Which topics of interest race to the top?
Note to readers: Page view statistics are only for the English version of Wikipedia, which has nearly 6 million total articles to date.
A One-Stop Shop of Information
Since its 2001 inception, Wikipedia has thrived as an open collaboration project, catapulting it into the ranks of the world’s top websites today. Over the years, the upper limit of views for the most popular pages has dramatically increased.
In 2008, the most popular Wikipedia page belonged to Barack Obama, during his U.S. Presidential campaign, garnering about 3 million views per month. By 2019, the page for the United States took its place at the top, this time soaring to nearly 200 million monthly views.
The 12 most popular Wikipedia pages fluctuate in category, with some expected winners. Throughout the years, World War II shows up consistently in the rankings, likely propelled by research for school assignments.
The U.S. is another undisputed, most-viewed page for nine years in a row (2011-2019). Following the November 2016 U.S. election, pageviews for Donald Trump also leapt into the top three.
Here’s how the most popular pages shake out over a decade:
|Rank||Jan 2008||Jan 2012||Jan 2016||Jan 2019|
|#2||U.S.||Lady Gaga||Barack Obama||Donald Trump|
|#3||Harry Potter||The Beatles||India||Barack Obama|
|#4||World War II||Barack Obama||Lady Gaga||India|
|#5||Kim Kardashian||Michael Jackson||Michael Jackson||World War II|
|#6||Britney Spears||India||World War II||Michael Jackson|
|#7||Miley Cyrus||Eminem||Game of Thrones||UK|
|#9||Lil Wayne||Lil Wayne||UK||Eminem|
|#10||India||World War II||The Beatles||Game of Thrones|
|#11||Will Smith||Glee (TV)||Justin Bieber||Elizabeth II|
|#12||UK||Justin Bieber||Adolf Hitler||Adolf Hitler|
Musicians also regularly top the charts, thanks to their illustrious careers and the public’s curiosity about their private lives. Michael Jackson holds a record for longest best-selling artist, but also for one of the most viewed Wikipedia pages, especially after his death in mid-2009.
A Crowdsourced Snapshot of the World
These popular Wikipedia pages provide an interesting angle on current events of the time, although it should be taken with a grain of salt.
For example, the 2008 financial crisis is arguably one of the biggest events of this decade—yet it doesn’t make an appearance in these most viewed pages. One possible reason is that more reputable sources of information exist about the event, as it was widely covered in the media.
Nevertheless, Wikipedia’s mission is to freely share knowledge, relying on over 250,000 monthly volunteers to keep its information accessible by anyone.
Breaking Down Barriers
Boasting over 50 million articles, it’s not hard to see why Wikipedia has reigned supreme as a crowdsourced catalog of information. However, a lesser known fact is that just one man is responsible for a significant chunk of the website’s English-language articles.
In 2017, Steven Pruitt was named one of Time Magazine’s “most influential people on the Internet” for making over 3 million edits and authoring 35,000 original pages on Wikipedia—all for free.
Pruitt is even helping to solve Wikipedia’s gender bias, and has expanded the share of biographical articles about women from 15% to 17.6% in a few short years.
I’m very conscious of what it can mean to make knowledge free, to make information free.
Visualizing the U.S. Airports with the Worst Flight Delays
With flight travel more than tripling in the past 30 years, we break down the most notorious airports in the U.S. with the worst flight delays.
Visualizing the U.S. Airports with the Worst Flight Delays
They say good things come to those who wait. In the case of flight passengers, however, some may be waiting much longer than others.
With frequent flights comes frequent problems. Unexpected travel irritations, delays, and cancellations are all common issues faced by flyers the world over. Correspondingly, certain airports have developed a reputation for making their passengers wait.
Today’s interactive chart from USAFacts shows the percentage of flights delayed, as well as the average length of those delays, at U.S. airports between October 2018 and September 2019.
The Top 10 Airports With the Longest Delays
In the worst airports across the country, over 25% of all flights get delayed. Here is a list of the top offenders based on percentage of flights delayed and the average delay, according to flight data.
|Rank||City||Airport||Percent of Flights Arriving Late||Average Delay Across Flights|
|#1||Newark||Newark Liberty International||26.5%||22 minutes|
|#2||New York||LaGuardia||24.5%||19.6 minutes|
|#3||Chicago||Chicago O'Hare International||25.5%||19.2 minutes|
|#4||Boston||Logan International||22%||17.3 minutes|
|#5||Dallas||Dallas/Fort Worth International||23.3%||16.5 minutes|
|#6||San Francisco||San Francisco International||22.4%||16.2 minutes|
|#7||Fort Lauderdale||Fort Lauderdale-Hollywood International||21.9%||16.3 minutes|
|#8||Denver||Denver International||21.6%||15.3 minutes|
|#9||Miami||Miami International||21.6%||15.3 minutes|
|#10||Chicago||Chicago Midway||22%||13.4 minutes|
Newark Liberty International takes the top spot, with 26.5% of all flights taking off late. To make matters worse, it also had the longest average delay time, at 22 minutes per flight. The runner-up is another New York-based airport, LaGuardia, averaging close to 20 minutes per flight delay.
The third worst offender was Chicago O’Hare International airport, where over a quarter of flights arrived late, with an average delay of 19 minutes. Chicago O’Hare International saw more flights than Newark and LaGuardia combined, making average delays more costly.
What’s Behind These Major Flight Delays?
While the New York area hosts two of the worst airports in the country, flight delays are exacerbated by a number of regional factors.
First, it hosts one of the busiest air corridors worldwide. As a result, any unexpected interruption or delay has an outsized effect on flights arriving at their destination on time.
Coupled with this is the commanding presence of United Airlines. As one of the largest airlines in the world, it operates over 401 daily flights at Newark airport. Additionally, United has been known to have operational issues. For example, in June 2019, significant aircraft problems led the Newark airport to suspend flights altogether.
There are four major causes of flight delays: poor weather conditions, late aircraft, carrier related (such as baggage, fueling, or maintenance problems), and airspace system issues.
According to this data, it’s clear that late aircraft is the most prevalent cause for flight delays that ended up being longer than 15 minutes.
Late aircraft creates a domino effect: when an airplane arrives late at an airport, a following flight that uses the same aircraft will depart behind schedule. In peak months such as July, this contributes to nearly 50% of flight delays.
Worst Months of the Year to Fly
The number of flights on U.S. airlines has more than tripled, from 275 million flights in 1978 to 889 million in 2018.
Along with this, flight activity is typically highest in the summer—coinciding with July’s highest average flight delay of 76 minutes. Months in the summer followed suit, with June averaging 72 minutes per delay and August having an average delay of 71 minutes, among flights that were delayed over 15 minutes.
|Month||Rank||Average Delay (in minutes)|
Perhaps surprisingly, flights in December bucked this trend. Even as a flight-heavy month, average long delays hovered around 60 minutes during the holiday season.
The 10 U.S. Airports with the Fewest Delays
By comparison, a number of airports appear to have avoided this trap. Data below shows the top airports in the U.S. with the fewest flight delays during the same time period.
|Rank||City||Airport||Percent of Flights Arriving Late||Average Delay Across Flights|
|#1||Honolulu||Daniel K Inouye International||10.5%||6.8 minutes|
|#2||Anchorage||Ted Stevens Anchorage International||11%||7.1 minutes|
|#3||Lihue||Lihue Airport||10.1%||7.7 minutes|
|#4||Long Beach||Long Beach Airport||12.6%||8.4 minutes|
|#5||Sacramento||Sacramento International||14%||8.6 minutes|
|#6||Kahului||Kahului Airport||12.7%||8.9 minutes|
|#7||Portland||Portland International||13.8%||9 minutes|
|#8||San Jose||Norman Y. Mineta San Jose International||14.9%||9.2 minutes|
|#9||Salt Lake City||Salt Lake City International||13.3%||9.7 minutes|
|#10||Santa Ana||John Wayne Airport-Orange County||14.7%||9.8 minutes|
As the volume of air travel continues to climb, it is clear that some airports underperform others by a wide margin. To break the vicious cycle of delays, it will be vital for airports to get initial flights departing on time in the first place.
Timelapse Maps: An Overview of Our Changing Planet
From rapid urbanization to retreating glaciers, these timelapsed satellite maps capture the drastic changes the Earth’s surface has undergone.
Humankind’s impact on the world is obvious, but our spatial patterns are sometimes difficult to recognize from the ground.
Publicly accessible, high-quality satellite imagery has been a game changer in terms of understanding the scope of forces such as urbanization and land use patterns.
Google Timelapse Maps
Google Earth’s timelapsed satellite maps capture the drastic changes the planet’s surface has undergone over the past 34 years. Each timelapse comprises 35 cloud-free pictures, which have been made interactive by the CREATE Lab at Carnegie Mellon University.
Three different satellites acquired 15 million images over the past three decades. The majority of the images come from Landsat, a joint USGS/NASA Earth observation program. For the years 2015 to 2018, Google combined imagery from Landsat 8 and Sentinel-2A. Sentinel is part of the European Commission and European Space Agency’s Copernicus Earth observation program.
Deforestation, urban growth, and natural resource extraction are just some of the human patterns and impacts that can be visualized.
Editor’s note: to view the following timelapses, press the play button on any map. You can also view individual years in the time periods as well. On slower internet connections you may need to have patience, as the series of images can take some time to load or display.
Cities and Infrastructure
Urban Growth: Pearl River Delta, China
Up to 1979, China’s Pearl River Delta had seen little urbanization. However in 1980, the People’s Republic of China established a special economic zone, Shenzhen, to attract foreign investment. In the following years, buildings and paved surfaces rapidly replaced the rural settings around the river delta. This is the Lunjiao area just south of Guangzhou.
Urban Growth: Cairo, Egypt
The present-day location of Cairo has been a city for more than 1,000 years, and its constrained urban footprint is now bursting at the seams thanks to Egypt’s population growth. A new city is being built in the nearby stretch of desert land (agricultural land is scarce) that will one day replace ancient Cairo as Egypt’s capital. If the government’s ambitious plans are realized, this desert boomtown could have a population of over 6 million people.
The Egyptian state needed this kind of project a long time ago. Cairo [is] a capital that is full of traffic jams, very crowded. The infrastructure cannot absorb more people.
– Khaled el-Husseiny Soliman
Urban Growth: Phoenix, Arizona
According to estimates from the U.S. Census Bureau, Phoenix is the fastest-growing city in the United States. Over the past two decades, the suburb of Chandler evolved from agricultural uses to sprawling residential developments. This pattern was repeated in a number of cities in the Southern U.S., most notably Las Vegas.
Construction: The Brandenburg Airport, Germany
Berlin’s long overdue Brandenburg Airport began construction in 2006, with the airport initially expected to open in 2011. However, the airport has been subject to numerous delays and the airport now has a new opening date. Berlin Brandenburg Airport is now expected to open on Oct. 31, 2020.
Megaproject: Yangshan Port
The Port of Shanghai became one of the most important transportation hubs in the world after the completion of its offshore expansion – the Yangshan Port.
Building this massive port was a gargantuan engineering feat. First, land reclamation was used to connect two islands 20 miles southeast of Shanghai. Next, the port was connected to the mainland via the Donghai Bridge, which opened in 2005 as the world’s longest sea crossing. The six-lane bridge took 6,000 workers two and half years to construct.
In 2016, the Port of Shanghai was the largest shipping port in the world, handling 37.1 million twenty-foot container equivalents.
Mining: Chuquicamata, Chile
Chuquicamata is the largest open pit copper mine by volume in the world, located 800 miles north of the Chilean capital, Santiago. In 2019, Chile’s national mining company Codelco initiated underground mining at Chuquicamata.
Deforestation: Ñuflo de Chávez, Bolivia
Ñuflo de Chávez is one of the 15 provinces of the Bolivian Santa Cruz Department. Satellite images of southern Ñuflo de Chávez illustrate deforestation from agrarian expansion in the jungles of the Amazon. From the air, the deforestation takes on a unique grid pattern with circular clearings. Developed as part of an organized resettlement scheme, each circle is anchored by community amenities and housing, and surrounded by fields of soybeans cultivated for export.
According to Brazil’s National Institute for Space Research, 8.4 million soccer fields of land have been deforested in the Amazon over the past decade.
Shale Gas Boom: Odessa, Texas
The small town of Odessa sits in the middle of one of the most productive shale gas regions in the world, the Permian Basin. The region is expected to generate an average of 3.9 million barrels per day, roughly a third of total U.S. oil production. While the gas may come from underground, the pursuit of this source of energy has drastically altered the landscape, marking the terrain with roads, wells, and housing for workers.
Drying of the Aral Sea: Kazakhstan and Uzbekistan
It took almost 30 years to make a sea disappear. When the Soviet Union diverted the Amu Darya and Syr Darya rivers to irrigate cotton and rice fields in the 1960s, it turned the Aral Sea into a desert. Once the world’s fourth largest lake, the region is struggling to restore water levels and aquatic habitats.
Glacier Retreat: Columbia Glacier, Alaska, USA
The Columbia Glacier is a tidewater glacier that flows through the valleys of the Chugach Mountains and into Alaska’s Prince William Sound. Increased temperatures initiated a retreat in the length of the glacier over three decades ago. Once in motion, a glacier’s retreat accelerates due to glacial mechanics. It is one of the most rapidly changing glaciers in the world.
Changing Rivers: Iquitos, Peru
Not all change is from humans. There are natural physical processes that continue to shape the Earth’s surface. For example, rivers that experience heavy water flows can be altered through erosion, changing the bends.
Better Perspectives, Better Decisions?
Often, the greatest impacts that occur are out of sight and mind. However, with the increasing availability of satellite technology and improved distribution of images through platforms such as Google Timelapse, the impact of human activity is impossible to ignore.
The bulk of visible changes come from human economic activity, because it is more easily observable on a smaller time scale. However, it’s also worth remembering that there are still many natural processes that take generations, if not thousands of years to affect change.
It is one thing to hear the facts and figures of humankind’s impact on the environment, but to see the change is a whole other story.
