Heatmap Video Shows the Migration of New Coronavirus Cases Over Time

Published

on

Today’s new animated heatmap comes to us from City-Data.com and follows the trends of new confirmed coronavirus cases around the United States over time. The animation was created using Leaflet.js, Folium Python library, and Monosnap and was shared by a member of the City-Data team on Reddit who goes by the name /u/absurddreams. All data was sourced from the New York Times. Check it out below:

It’s no secret that an early epicenter of the coronavirus pandemic in the United States was New York City. As we now know, even though the virus itself originated in China, the origin of the major outbreak in New York has been traced to travelers from Europe. In the first few months of 2020, millions of travelers came to the U.S. from Europe through major NYC-area airports such as John F. Kennedy International Airport (JFK) and Newark Liberty International Airport (EWR).

A Time Line of Notable Trends:

  • As the animation begins to unfold, a few hotspots begin to emerge, the most obvious of which is the aforementioned NYC area.
  • As the end of April comes to pass, a number of pockets throughout the Central United States are visible, but the Northeastern United States are still dominate.
  • However, when mid-May arrives, New York and the rest of the Northeast have faded significantly.
  • By mid-June, new COVID-19 cases in the Northeast are negligible, almost completely gone, and the worst zones have shifted to Southern states where several growing pockets have emerged.
  • As the clock dials around to present day (July 7th) the Southern states, particularly from eastern Texas to South Carolina, are inundated with new coronavirus cases.

The unfortunate and alarming surge in cases across the Southern and even Western states is likely an unfortunate side effect of states failing to impose lockdowns and guidelines to prevent the spread of the virus early on.

The sharp decline in New York and Northeast COVID-19 cases has been attributed to the comprehensive stay-at-home orders, face mask requirements, social distancing guidelines, etc. that were organized by those states. They have flatted the curve for now, but the pandemic is far from over.

Mapping Rates of Drowsy Driving

Published

on

This map from NapLab highlights the locations with the highest instances of drowsy driving. This is such an important topic to study and gather data on. The National Highway Traffic Safety Administration says that in 2022, 693 people died in drowsy-driving-related crashes. Many people push their limits behind the wheel when they’re tired. After all, if you’re exhausted while traveling, nothing sounds more appealing than hurrying home to your warm, familiar bed. But maps like this one illustrate just how risky this decision can be.

The team at NapLab studied fatalities in drowsy driving accidents, adjusted rates by population density and then mapped out the locations that had the most accidents. Here are their findings.

Mapping the Drunk Driving Epidemic

Published

on

It’s illegal to drive if your blood alcohol content is over .08%. Even so, every year Americans have too much to drink and choose to get behind the wheel anyway causing traffic accidents across the country that can cause injury and even death. Drunk driving is clearly an epidemic. According to Mothers Against Drunk Driving, car crashes are the leading cause of death among teenagers and 1 in 4 of those crashes involve an underage drunk driver. The facts are clear. Drunk driving is rampant and can claim lives or grievously someone no matter their age.

The team at van der Veen, Hartshorn, Levin & Lindheim created a map that highlights the severity of the drunk driving problem and examines a specific aspect: location. They used data from the National Highway Traffic Safety Administration to calculate which cities had the highest numbers of drunk driving fatalities per 100,000 people. They created a map that shows areas where drunk driving occurs the most and may even help us reach new conclusions about why some places are more at risk of drunk driving and others. Is your city highlighted?

The map is the best way to look at these trends, but here’s a quick list of their top ten results:

  1. Odessa, TX: 27.46
  2. San Bernardino, CA: 18.15
  3. Pueblo, CO: 17.94
  4. Corona, CA: 15.04

The 50 States Ranked by How Appealing They Are for Boating

Published

on

Boat lovers have a new way to pick their dream destination with this chart ranking states by how desirable they are for boaters. The SI Yachts team used a detailed scoring system to rank these states. The system considers some of the major factors important to boaters like average temperatures, number of sunny and cloudy days, amount of coastline, lakes, and rivers, hurricane risk, number of boats owned in the state, and the average cost of boater’s insurance. All these factors, averaged together, created the team’s ultimate list of boating states.

Despite the hurricane risks, Louisiana still comes out on top as the best state for boating. Miles and miles of coastline and waterways, low swampy areas, and a fishing legacy make boating a way of life in the Bayou State. As for the bottom of the list, New York was not the Empire State for boating. Expensive boater’s insurance and few days of ideal weather meant that despite this state’s abundance of lakes, rivers, and coastline, it just wasn’t an ideal place to own a boat.

Every boater has different priorities to guide where they want to set sail, but this chart is a great way to consider where you’ll find a boater’s paradise. There’s a great diversity of regions in the top states on this list so East or West, North or South, you’ll find the perfect boating destination.
