Interactive map lays bare America’s devastating overdose epidemic: Analysis of 15 years of data reveals key ages, genders, regions, and drugs behind the crisis

  • Overdose deaths have increased 137% since 2000; more than 50,000 Americans fatally overdosed in 2015
  • This interactive map, using CDC statistics, puts the staggering epidemic into context
  •  It breaks down the statistics into gender, age group, drug preference, and region
  • The steepest increase in overdose deaths has been among those aged between 65 and 74 years old 

Prescription opioids and illicit drugs have become incredibly pervasive throughout the U.S., and things are only getting worse.

Overdose deaths have increased 137 percent since 2000.

In fact, new figures released today revealed more than 50,000 Americans died from drug overdoses last year – the highest figure ever.

Fentanyl, a painkiller, causes 44 deaths every day, making it the most dangerous drug in America.

An analysis of 15 years of data shows the steepest increase in overdose deaths has been among those aged between 65 and 74 years old – going from 16 deaths in 1999, to 680 deaths in 2014, a 4,150 percent increase.

This is likely to do with chronic pain and un-monitored prescription opioid refills, as well as those turning to cheaper on-the-street alternatives – like heroin – when they cannot afford pharmaceutical drugs.

Opioids – which are legal, controlled substances often prescribed by doctors – have caused a 200 percent increase in overdose deaths.

5 GIS Projects that are Changing the Way we Understand Racism

Within the fields of history and journalism, the use of GIS (Geographic Information Systems) has greatly changed the way we visualize, understand, and analyze racial bias within the United States and the globe. Maps have always been a way that we were able to conceptualize the topography of our universe, and now the use of GIS has given us more insight into the inequality embedded in our country than ever before. Below are just a few of the projects working to use spatial analysis in order to reveal the historical and current prejudices that people of color face every day.

Wastewater and Oklahoma Earthquake

Wastewater Disposal Likely Induced February 2016 Magnitude 5.1 Oklahoma Earthquake

 Distant wastewater disposal wells likely induced the third largest earthquake in recent Oklahoma record, the Feb. 13, 2016, magnitude 5.1 event roughly 32 kilometers northwest of Fairview, Oklahoma. These findings from the U.S. Geological Survey are available in the online edition of Geophysical Research Letters.

At the time, the Fairview earthquake was the largest event in the central and eastern United States since a 2011 magnitude 5.7 struck Prague, Oklahoma. The 5.1 magnitude event occurred southwest of a group of high-rate wastewater disposal wells greater than 12 kilometers away. In the region surrounding the Fairview earthquake sequence, the volume of fluid injected increased 7-fold over three years.

”The fact that seismicity is rather limited near the high-rate wells while the Fairview sequence occurred at a relatively larger distance from these wells, shows us the critical role preexisting, though possibly unknown, fault structures play in inducing large events,” said Dr. William Yeck, a USGS scientist and lead author of the study. “The rapid deployment of seismic stations by the USGS allowed us to precisely locate the aftershock sequence. High-quality data sets such as these are critical when trying to understand the shaking produced by these events and therefore are an important basis for earthquake hazard modeling.”

Earthquakes in this area primarily occur at depths of 6 to 9 kilometers, roughly 3.5 to 6.5 kilometers below the Arbuckle Group in which wastewater is typically injected.

On September 3, 2016, Oklahoma experienced the largest earthquake since 2011 when a magnitude 5.8 earthquake occurred near Pawnee, Oklahoma.

While the relationship between the Pawnee earthquake and wastewater injection is still under investigation, studies such as this further scientific understanding of the complex relationship between wastewater disposal and earthquakes.
