As a newspaper reporter living in South Korea, I’m always aware that a “provocation” by our friends in the North — a missile launch, a nuclear test, or some other incident — could occur on any day.
A recent missile launch came on a Sunday morning, for example, disrupting our family plans. (That’s part of the job, of course).
But which days have been more likely for provocations, I wondered? Thanks to a handy database from the Center for Strategic & International Studies, we now know.
Since 2001, North Korean leaders seem to prefer … Mondays?
The trend is clear in the data: Compared with any other day, provocations have been twice as common on the first work day of the week.
The data also reveal some interesting tidbits about the North’s provocations. Thanks to a recent surge in missile tests, the number of provocations has increased substantially under the new leader, Kim Jong Un, who took power in late December 2011 after the death of his father, Kim Jong Il:
The Center categorizes the provocations by type, too (though I broke our “exchange of fire” incidents from “Other” in the data):
And here you can see the interest in missile tests. Roughly half of all provocations since 2001 have been missile launches or tests (again, propelled in part by Kim Jong Un’s recent interest):
I’ve just finished watching ESPN’s fabulousO.J.: Made in America, a five-part documentary about the Hall of Fame football player.
Somewhere in the process of digesting this latest — and, perhaps, best — telling of O.J.’s story, I scoured Wikipedia for details about his life. I discovered that the page has been edited more than 4,000 times since it went up in 2003, back when Wikipedia user “Vera Cruz” posted the first biographical snippet.
Since then, users have slowly edited — and vandalized — the current bio’s 5,000 words, a process I’ve charted below.
Outsiders, like me, who are trying to understand how much immigration is driving the “Brexit” debate about the European Union might consider this fact: Britons are much more likely today to encounter people born in another country — both inside and outside Europe — than they were a decade ago.
In 2014, about 1 in 8 people residents were born outside the U.K. — up from about 1 in 11 a decade earlier, according to government statistics.
The view from our apartment in Seoul. Some days are better than others.
The air quality in Seoul — a mega city home to 70,000 taxis and 10 million residents — can get rough at times, especially for people already sensitive to pollution. It’s been an adjustment for my family, though it could be worse.
We could live in Beijing or Shanghai.
This chart, from a recent work collaboration with my wife, shows the number of days in 2015 that the pollutant PM2.5 reached certain health thresholds in the U.S. Environmental Protection Agency’s air quality index. It compares Seoul to Beijing and Shanghai in China and New York and Los Angeles in the U.S.
Seoul isn’t terrible — but it isn’t great, either:
Last week we examined how the Democratic presidential campaigns have performed in the context of Barack Obama’s 2012 re-election.
That analysis grouped Obama’s vote share into categories, highlighting how the country’s reddest and bluest counties have voted for Hillary Clinton and Bernie Sanders so far in the Democratic primaries. Clinton, the clear frontrunner, performed best in areas where Obama was strongest against Mitt Romney. But Sanders did slightly better when majority black counties weren’t factored.
Here’s a look at the Democratic race (through the most-recent contests) in the context of voters’ educational attainment. Each candidate’s average vote share by county is grouped by the proportion of residents in those areas with at least a bachelor’s degree. Sanders doesn’t win among any group, but he generally performs best in places where voters have more education:
Does Washington, D.C., have more cops than other cities? That’s the question I asked myself the other day after watching a patrol car drive down our quiet, residential street. I see patrol cars everywhere — much more often than I did previous cities like Houston and Austin.
There’s a reason: Among the top 50 most-populous local governments, D.C. simply has more police officers per resident, according to the U.S. Department of Justice, which surveyed large police forces a few years ago. The city has about 670 cops per 100,000 residents, well ahead of Chicago, which was second with about 472 per 100,000. Houston had about 220, and Dallas had about 260.
Of course, D.C. is the capitol and diplomatic center of the country, and it’s densely populated with pockets of high crime and poverty. So a large officer to resident rate is understandable. But it’s a bit surprising how much D.C.’s ratio eclipses that of other major cities.
This chart shows the cities among the top 50 that have the highest per-resident officer ratio:
Here are the data for all 50 cities plotted on a map made with TileMill. Larger symbols represent higher numbers of officers per 100,000 residents:
[A]n investigation by The New York Times has found that industry practices continue to put animal and rider at risk. A computer analysis of data from more than 150,000 races, along with injury reports, drug test results and interviews, shows an industry still mired in a culture of drugs and lax regulation and a fatal breakdown rate that remains far worse than in most of the world.
The story has a chart and map visualizing the rate of incidents at each track, showing how it varies by state:
Back in October I posted line charts illustrating Herman Cain’s rise in popularity among GOP — and Texas Gov. Rick Perry’s descent after some unsteady debate performances. Yesterday Google released its 2011 “zeitgeist” report, which visualizes worldwide searches during the last year, allowing another comparison of the two men.
This (unnecessarily 3D?) chart shows the 10 fastest-rising searches in politics news during a critical point in the primary for both candidates. You can see when Cain (in green) began his slide, following allegations of sexual harassment. Perry (in blue) also dropped after the “oops” moment in early November:
