The Deadliest Building Collapses of All Time

Published

on

People aren’t perfect. Mistakes happen. Sometimes a mistake can cause an inconvenience and some mistakes have more severe consequences. If an architect, engineer, or builder makes a mistake those consequences can be deadly. Unfortunately, there have been a number of devastating structure collapses throughout history that have claimed a huge number of lives. Some were due to the negligence or incompetence of those who built it and some had other causes such as natural disasters or terrorism. This map and visualization from ForneyVault reveals the 30 deadliest building failures in history. Check it out here:

The map above cleverly visualizes each building collapse using 3-D bars on a grid world map; the height of each bar represents the death toll. Towering above the rest is the deadliest building collapse in history which took place in 27 C.E. in ancient Rome when a poorly constructed amphitheater collapsed, killing 20,000 people. Next up took place in 1809 when 4,000 people perished after a floating bridge collapsed in Portugal.

The most recent on the list is another sad tale of negligence by those who built the structure. In 2016 in Taiwan, a residential building collapsed after an earthquake, 116 people were killed. At first, it seemed like it was a natural collapse resulting from the earthquake but it became apparent after searching the rubble that cooking oil cans had been used as structural materials and that the concrete had been mixed with other materials, rendering the building unsafe.

We were surprised to see that the infamous Surfside condominum collapse which took place near Miami in 2021 does not make the list with its 98 fatalities as the 30th and final building collapse incident on the list involved 111 deaths.

To put things into perspective, consider that the global average cost of 1 GB of data is $4.07. Compare that to the most expensive country, Equatorial Guinea, where people pay an average of $49.67 for 1 GB! Israel has the least expensive data in the world at just $.05 per 1 GB. What can you do with 1 GB of data? According to MakeUseOf.com, 1 GB of data equals five hours of mobile web browsing, 30 minutes of HD video streaming, five hours of mobile gaming, and 18 hours of music streaming. That means in the most expensive country, it could cost around $200 just to watch a movie on your phone! In Israel, you could watch it for $.20. Overall, this chart is effective at conveying mobile data prices around the world in a quick and compelling way. How much do you pay for mobile data and where do you live? We would love to hear from you in the comments!

Which Cities Truly Never Sleep? This Chart Shows the Cities With the Most Night Workers

Published

on

The world never truly sleeps – humans are working hard around the clock trying to make a living, provide for their families, afford their hobbies, or just make it to the next meal. While many of us are blissfully sinking into our pillows, night shift workers are just beginning their “day” of work. A typical night shift, or third shift, involves working from 11:00 PM to 7:00 AM or 5 PM to 2 AM. So where are these night workers most abundant? NapLab has created a chart exploring the U.S. cities with the most people working night jobs. Before you scroll down, take a guess at the top city. I did my first time discovering it – I’ll share my answer below!

My initial guess was Detroit, Michigan. I have never been, but something about it just oozes “burning the midnight oil”. What was your guess? Comment below! In reality, the top city with the most night workers is Las Vegas, Nevada, which actually makes absolute sense considering its reputation for a dazzling, chaotic and never-ending nightlife. 16.53% of Vegas’ workforce works the night shift! After all, you would never expect a city with the monikers “Sin City”, “Neon Capital of the World”, “Entertainment Capital of the World” and “City of Light” to become a quiet little hamlet once the sun sets. I felt a little better when I discovered that my guess, Detroit, ranks 28th with 11.93% of the workforce manning the night shift.

Overall, I appreciate the overall feel of the chart – the colors convey the topic exceptionally, and the header is lovely and eye-catching. I have never seen this data visualized before, so I appreciate the opportunity to learn something new about the culture and economy of America.

U.S. Cities Where Home Prices Have Increased the Most Since the Pandemic

Published

on

The COVID-19 pandemic has impacted prices and expenses across the board. From groceries to living costs, most people are feeling a hit to their wallets. Housing costs in particular have been rising exponentially. Where in the United States have they been rising the most?

The following visualization shows where in the U.S. home prices have increased the most since the pandemic. The graphic utilizes a pin map at the top to indicate where each of the cities are located, and then uses a column range chart to depict the change in home prices between January 2020 and July 2022.

These are the cities that have seen the biggest increase in home prices since the beginning of the pandemic in 2020:

  1. Cape Coral, FL: 85.96%
  2. Round Rock, TX: 80.94%
  3. St. Petersburg, FL: 76.92%
  4. Port St. Lucie, FL: 72.88%
  5. Clearwater, FL: 71.09%
  6. Surprise, AZ: 69.93%
  7. Nampa, ID: 69.69%
  8. Tampa, FL: 69.35%
  9. Austin, TX: 69.05%
  10. Gilbert, AZ: 68.54%

Unsurprisingly, since many employees are now allowed to work from home, warmer locations have become popular places for relocation. This could play a part in why home prices are increasing in states like Florida and Arizona.

On the flip side, these are the cities where home prices have risen the least since the pandemic:

  1. Odessa, TX: -1.98%
  2. Midland, TX: 6.27%
  3. Washington, DC: 10.47%
  4. San Francisco, CA: 11.27%
  5. Las Cruces, NM: 11.35%
  6. New York, NY: 12.95%
  7. Laredo, TX: 15.85%
  8. Boston, MA: 15.91%
  9. Minneapolis, MN: 16.72%
  10. Shreveport, LA: 16.96%

Odessa, TX is the only place where home prices have decreased. Major cities like San Francisco, New York City, and Boston have also experienced low levels of home price increases, likely due to many people leaving large cities during the pandemic.

Which city on the list is most surprising to you?
