After spiking in the 1980s, crime rates in the United States – for both violent and property crimes – fell significantly in the last two decades. In particular, the rate of violent crime (murder, rape, aggravated assault and burglary) by 2012 had dropped to less than half what it was in 1991, according to FBI data (from 758 violent crimes per 100,000 Americans to 387). And although a disproportionately high level of violent crime still occurs in densely populated urban areas, many of America’s big cities experienced similar downward trends. That includes the nation’s two largest metropolises — New York and Los Angeles — both of which had precipitous drops in violent crime. Continue reading

If you live in California, snowpack is a pretty crucial part of your existence.
That’s because about a third of the state’s water supply comes from snow that accumulates in the mountains, mostly during the winter months. In fact, California receives roughly half of its entire year’s water supply between December and February alone. Continue reading
As President Obama delivered his fifth State of the Union address last night, the Twittersphere was, unsurprisingly, abuzz with commentary and reactions. To show which parts of the speech struck a chord — or a nerve — Twitter data viz whiz Nicolas Belmonte created the following interactive visualization. It attempts to gauge the resonance of the various topics Obama addressed by linking every paragraph in the speech to the thousands of Tweets submitted directly in response, and geographically tracing where those Tweets originated.

This is not a good time for umbrella merchants in California.
2013 was one of the driest years on record in the state. And January – usually among the wettest months — has failed to provide any relief. With the precipitous drop in reservoir levels, Gov. Jerry Brown recently declared a statewide drought emergency, calling this “perhaps the worst drought California has ever seen since records began being kept about 100 years ago,” Continue reading
Beware the lure of that plastic in your wallet!
According to the Federal Reserve data, the average indebted U.S. household in 2013 shouldered credit card debt of more than $15,000 (although that figure is skewed by a relatively small number of extremely debt-ridden families). While U.S. credit card debt has fallen since the height of the recent recession, and pales in comparison to average mortgage debt (about $148,000) and student loan debt (about $32,000), it still remains a major burden for millions of U.S. consumers who cumulatively owe upwards of $850 billion to credit card companies.
So how do credit cards actually work? And more importantly, how do the credit card companies make their millions from all your swipes? Animator Josh Kurz explains.
Josh Kurz started out as an embryo, 53 times smaller than a US nickel. Born and raised in Brooklyn, New York, he began at an early age fusing the abstract concepts of science and comedy. Now he works as an independent filmmaker specializing in humorous science explainers ranging from the economics of voting to why some people (like he himself) hate cilantro. His work has been featured on WGBH, ABC, PBS, NPR, TEDed, and Radiolab.
During his State of the Union Address delivered 50 years ago on January 8, 1964, President Lyndon B. Johnson declared “unconditional war on poverty in America.” At the time, roughly 19 percent of Americans were living below the newly developed federal poverty line. Johnson’s declaration ushered in a wave of social welfare legislation — part of a set of domestic reforms that became known as “The Great Society.” It led to the creation of health and education safety net programs like Medicare, Medicaid, Head Start and food stamps. By 1969, when he left office, the poverty rate had dropped by more than a third, to about 12 percent. Continue reading
2013 provided endless journalistic opportunities for number-crunching and data-based storytelling. Below, in no particular order, are 10 memorable visualizations featured this year on The Lowdown.
The 2013 news cycle came with nary a dull moment.
From the Boston marathon bombings, NSA leaks and same-sex marriage Supreme Court decisions, to the George Zimmerman verdict, government shutdown and health care exchange fiasco, there was an abundance of game-changing news this year in the United States, replete with a steady flow of provocative headlines. In this interactive timeline, Andrea Caumont and George Gao at Pew Research chart 20 of the biggest stories of the year, noting how the public reacted based on polls conducted in the aftermath of each event.

If you gamble on faith — not on odds — you might want to stop reading this now. Because the chances of winning just about any big stakes lottery game — like Mega Millions — is just north of impossible. Let’s take Powerball, for instance. Odds of winning the jackpot: about 1 in 175 million. By comparison, your odds of getting hit by lightening — a presumably less favorable outcome — are significantly higher. So, be sure to take shelter during thunderstorms, and, if you play the lottery: you might not want to quit your day job just yet. But hey, you never know, right? People win all the time. In this animation and accompanying infographic, animator Joe Golling explains how to calculate the mathematical possibilities of buying the winning ticket.
