1.5 Million Missing Black Men


Figures are for non-incarcerated adults who are 25 to 54. In New York, almost 120,000 black men between the ages of 25 and 54 are missing from everyday life. In Chicago, 45,000 are, and more than 30,000 are missing in Philadelphia. Across the South – from North Charleston, S.C., through Georgia, Alabama and Mississippi and up into Ferguson, Mo.

The State Of The Cancer Nation


While a cure for cancer remains elusive, we already know how to keep many cases of the disease from developing in the first place. People can reduce cancer risks by keeping a healthful weight and avoiding cigarettes. But smoking, obesity and other major cancer risk factors remain common, and they still vary widely across the country.

200 Years Of U.S. Immigration


In 1819, Congress passed a law requiring that the arrival of all immigrants be recorded. Immigrant workers were needed, and the rest of the 19th century saw their numbers grow. From that period through today, America has seen waves of immigration, which Natalia Bronshtein has captured in a colorful interactive graphic.

Diversity in the Toss-Up States

“Mr. Bush, the former governor of Florida, would likely target more diverse states with growing Hispanic populations, while Mr. Walker, the governor of Wisconsin, would focus on working-class white voters in the Midwest.”


Should Jeb Bush or Scott Walker become the Republican presidential nominee, their paths to victory would look very different.

A Century Of Global Plane Crashes

Investigators still want to know what caused a civilian airliner to crash Tuesday morning in the French Alps. The incident, which likely killed 144 passengers and six crew members aboard the Airbus A320 destined for Germany, is one of at least 17 major crashes this year, according to the Bureau of Aircraft Accident Archives.

The group maintains a detailed database of each crash back to 1918, the early days of flight, allowing users to search 22,000 cases by year, operator, plane type and cause, among several other variables. This one is at least the 18th involving an Airbus A320, according to the database.

The chart below shows the number of crashes catalogued by the group during that time. You can see a spike in 1944, during World War II, when many military aircraft went down in battle, resulting in more than 4,300 casualties:

Since then, the number of crashes peaked in 1978 and has declined over time. There were about 120 crashes last year, according to the bureau’s records.

DC, Seoul Share Similar Climate — Until The Summer Rains Come

As I noted yesterday, we can expect similar weather here in Seoul as we experienced in Washington, D.C., where we lived until earlier this month. The two capital cities are located about the same distance from the Equator, along the 38th parallel north.

We’ll be in for something different this summer, however. That’s when the rains come. On average, Seoul gets about 35 inches of rain during July and August alone. To put that in perspective, our former home city, Austin, receives about the same amount annually. Seoul gets more rain in these months than most major cities in the American West, in fact.

Compare Austin, Seoul and Washington, D.C., in this chart:

The number of days with some rain also spikes a bit during the Seoul summer. Again, compare the cities:
