Now that You’ve Finished Your Taxes (Hopefully), See What They Actually Pay For

Estimation based on income taxes only (not payroll taxes).

“In this world,” wrote Ben Franklin, “nothing can be said to be certain except death and taxes.”

On April 15, as the filing deadline closed in, millions of Americans were frantically confronting that latter (but hopefully not former) inevitability. Continue reading

Equal Pay Day: How Big is the Wage Gap Between Men and Women?

April 14 is Equal Pay Day, symbolizing the number of days into 2015 (in addition to all of 2014) that the average American woman would need to work in order to match what the average man made in 2014 alone, according to Department of Labor estimates.

Although the the gender wage gap has significantly narrowed in recent decades, it still persists to a notable degree. According to the DOL, women are paid on average 78 cents for every dollar made by a man. That gap is even wider for women of color. Continue reading

CORRECTION: This article originally stated that soy milk was the most water-intensive drink. The  value, as initially listed by the LA Times, was for the soybean ingredient, not the actual final soy milk product. Soy milk actually has a smaller water footprint than most other processed drinks.

Looking to minimize your water footprint at the dinner table? How about a wholesome meal of eggs, carrots, potatoes and beer?

Nutritious and downright water efficient (although perhaps not age-appropriate for the whole family).  Continue reading

March Madness by the Money: Should College Players Get Paid?

Courtesy Wikipedia


March is winding down, and that means millions of Americans camping out on their couches and taking suspiciously long lunch breaks to witness the dwindling cadre of basketball squads battling it out for intercollegiate glory.

Although college athletes are considered “amateurs” by the NCAA, and prohibited from collecting any kind of monetary compensation (including royalties from sponsorships), the tournament they play in has become very big business, generating massive profits for the National College Athletic Association and many of the coaches and schools involved.   Continue reading

Multimedia Roundup: ISIS Explained

The Islamic State, a radical religious group that in the past year has violently seized huge chunks of territory in eastern Syria and northern and western Iraq, is widely considered among the world’s most violent and dangerous new terrorist forces. Also referred to as ISIS or IS, the group is known for use of brutal tactics, including mass killings and beheadings of journalists and aid workers, to spread a message of fear and establish a medieval-style religious order throughout the region. But much mystery about the group remains. These resources help explain who exactly the Islamic State is, what it wants and the surprisingly sophisticated media tactics it uses to spread its message and attract new recruits. Continue reading

Where Does Your T-Shirt Come From? Follow Its Epic Global Journey [Visualization]

[Re-run Alert! A version of this post was first published in June 2013]

Best viewed in full-screen mode (click on button at bottom left corner after loading)

A simple cotton T-shirt doesn’t seem so simple when you begin to trace the various steps in the now-standard vast global process from cotton farm to clothing shop.

The extraordinary success of “fast fashion” giants like H&M, Zana and Forever 21, lies squarely in the ability to produce a massive amount of clothing – billions of garments a year – in the cheapest, quickest manner possible. It may seem counterintuitive, then, to divide the process into manufacturing hubs scattered around the globe.  But when you factor in the dramatically lower labor and material costs offered by suppliers in developing countries, the global supply chain model begins to make more sense.

Interactive Map: See How the Ebola Outbreak Spread

It’s been over a year since the worst Ebola outbreak in history began to ravage the West African nations of Guinea, Sierra Leone and Liberia. To date, the highly infectious virus has claimed the lives of nearly 10,000 recorded victims. And although the epidemic’s spread has significantly slowed, with patients confined to a shrinking geographic region, there’s still no known cure and more than 100 reported new cases each week, according to the World Health Organization. In the interactive map sequence below, Frontline traces the epidemic’s spread from its suspected emergence with Patient Zero back in December 2013.
