Governments, schools and companies all keep track of your race. The stats they collect are used to track the proportion of blacks and whites who graduate from school, for example. They tell us how many people identify themselves as Native American or Asian. They help us to measure health disparities between races. But there's a problem with all of those statistics and with the deeper way that we think about race. NPR's social science correspondent Shankar Vedantam is here to explain. Hi, Shankar.
This is MORNING EDITION from NPR News. I'm Renee Montagne.
STEVE INSKEEP, HOST:
And I'm Steve Inskeep. Most Americans who own a house know something about housing bubbles. This country is still recovering from the last one.
MONTAGNE: In Afghanistan, a housing bubble created by the influx of international organizations and their thousands of workers over the past 12 years, is bursting, and it's taking a big bite out of the local economy. NPR's Sean Carberry can hear the last gasp of that bubble on his own street.
NBC says its coverage of the Winter Olympics drew more than 100 million viewers over the last weekend of the Games. That indicates lots of interest, which will fill more than 1,500 hours of coverage across all of NBC's platforms - broadcast network, cable channels and online. With all this coverage and so many ways to watch, we turn to NPR television critic now, Eric Deggans for some tips. Good morning.
ERIC DEGGANS, BYLINE: Good morning.
MONTAGNE: How are fans getting their Olympics coverage these days - for the most part?
Wednesday, the American women's hockey team meets its arch rival Canada on the ice in Sochi at the Winter Olympics. It's an early round game, but when it comes to these two teams, which are expected to meet in the gold medal game, there's no such thing as a low-stakes match.
Let's say you're skiing in the backcountry, looking for some powder — but instead, you trigger an avalanche.
If you have an avalanche air bag pack strapped to your back, you just yank the cord. That deploys the air bag, which keeps you close to the surface and easier to dig out, says Andy Wenberg with Backcountry Access, one of several companies making the devices. When deployed, his company's version of the air bag comes out like wings.
"The whole idea when you deploy that thing in an avalanche is you're avoiding burial death," he says.
