Good Time Charts, Bad Time Charts

How do you graph data to show changes over time? You might make “years” your x-axis and plot each year’s number. But you’re not the Washington Post. If you’re the Post Wonkblog (here), first you proclaim:

Here is that single chart.

(Click on a chart for a slightly larger view.)

The data points are years, but the seem to be in no logical order, and they overlap so much that you can’t tell which year is where.  Even for a point we can easily identify, 1987, it’s not clear what we are supposed to get.  In that year, the average income of the lower 90% of earners was about $33,000, and the average for the top 1% was about $500,000. But how was that different from 1980 or 1990. Go ahead, find those years. I’ll wait.

Here’s the same data,* different graph.

The point is clearer: beginning in 1980 or thereabouts, the 1% started pulling away from the lower 90%. 

A graph showing the percentage change shows the historical trends still more clearly.

From the mid-40s to 1980, incomes for the lower 90% were growing more rapidly than were incomes for the 1%. This period is what some now call “the great compression,” when income inequality decreased. Since 1980, income growth for the 90% has leveled off while incomes for the 1% have risen dramatically.

(The Post acknowledges that it got its material from Quoctrong Bui at NPR. But the NPR page (here) has two graphs, and the one that is similar to the one in the Post has an time-series animation that shows the year to year changes.)

Odd “Even”

April 10, 2015
Posted by Jay Livingston

The “Mad Men” exhibit at the Museum of the Moving Image shows how scrupulously Matt Weiner and company sought historical authenticity. They are proud of their period-perfect props, objects that we will glimpse for a split second or not at all – the lunches in the office fridge, the driver’s license in Don Draper’s wallet.

Why, then, does nobody check the script for linguistic anachronisms? I’ve noted some of these before (here). In this seventh and final season, “even” has popped up ahead of its time.  In an episode before the mid-season break, Bert and Don have this conversation. The year is 1970.


                                               

Here’s the transcript:
Bert:  You thought there was going to be a big creative crisis and we'd pull you off the bench, but in fact, we've been doing just fine.
Don:  So, why am I even here?

To my ears, that “even” sounded odd, a bit too recent.  Mark Liberman at the Langauge Log agrees. In a 2011 post (here) on the history of “even,” he says that this use of “even” for emphasis is very recent.

The specific phrase "what does that even mean?" has become fairly common in the news media and in books, but most of the hits are from the past decade. . . . I don't remember this expression from my youth, and I can't find any convincing examples before 1993.

Google nGrams too shows that the sharp rise does not begin until after 1980.

In another Season 7 episode, teenage Sally, briefly home from boarding school, has a confrontation withe her mother. Echoing Dad she says, “Why am I even here.”

For the final episodes, Weiner has brought legendary screen writer and screen doctor Robert Towne on board. Towne was born in 1934, and he has an ear for dialogue. Maybe he will be able to keep the language suited to the historical period.

My Handshakes Bring All the Boys to the Yard

Handshakes are important. They can make a difference.

After Kentucky lost to Wisconsin in the semis Saturday night, several of the Wildcats started off the court, skipping the handshake line.The Kentucky coaches managed to round up some of them, but three of the Kentucky stars shook no hands.* 

That was now. But this Kentucky-handshake contretemps seems to be history repeating itself, albeit with some color reversal.

In 1950, for post-season basketball, the NCAA had a close rival in the NIT. The “I” stands for “invitational,” and Kentucky, always a basketball power, easily won an invite. City College was a bit iffier, but they too were invited, and in the second round they matched up against Kentucky, coached by the legendary Adolph Rupp.

Part of the Rupp legend was racism.  According to journalist Marvin Kalb, Rupp had been quoted saying he’d never coach a team with “kikes” and “blacks.”  This was still in the days when Southern universities were segregated. The Kentucky squad was all White, all Christian, something of a contrast to the City College starting five – three Jews and two Blacks.

Kentucky was a heavy favorite. City College coach Nat Holman knew that if his team was going to have a chance, he would have to get his players really psyched up. So he told his players to show their sportsmanship before the game by shaking hands with their Kentucky counterparts. The City College players went to their positions for the opening tip-off and, following coach’s orders, each extended a hand to the Wildcat standing next to him. Before a crowd of 18,000 at the Garden, the Kentucky players turned away. No handshakes from the Wildcats.

The scenario had the effect Holman had intended. The City College players were, to say the least, fired up. Final score: City College 89, Kentucky 50. That may still stand as the worst loss in Kentucky’s history.

Sure there are differences – the no-handshake before rather than after the game, the players doing the snubbing Black, the snubbees mostly White. But the similarities – Kentucky, no handshake, loss to a Northern team – were a thematic echo I found too intriguing to pass up.
---------------------------
* Some observers lumped this unsportsmanlike conduct together with Andrew Harrison’s comment about Wisconsin’s center Frank Kaminsky. In a post-game team interview, when a reporter asked a question about Kaminsky, Harrison, thinking he was off-mike, muttered, “Fuck that nigga.” I see this less as poor sportsmanship than as grudging admiration. If I were Kaminsky, I wouldn’t be offended. I’d be flattered.

Cops – Killing and Being Killed

April 3, 2015

This story from Kos has been quickly circling through the left portion of the Internet.

Let’s assume that the numbers are accurate.*

Don't bother adjusting for population differences, or poverty, or mental illness, or anything else. The sheer fact that American police kill TWICE as many people per month as police have killed in the modern history of the United Kingdom is sick, preposterous, and alarming.

The author is right. Although the US has a much larger population, and it has more police officers . . .

(Click on the graph for a larger view.)

. . .but even adjusting for that, the US killings by cops dwarf the UK figure**.

Adjusting for the number of cops, US cops killed 8 times as many people in a single year as UK cops did in 115 years. But before we conclude that US law enforcement is “sick and preposterous” and dominated by homicidal racists, we might look at the other side – the number of cops who get killed. The entire UK police force since 1900 has had 249 deaths in the line of duty. The US tally eclipses that in a couple of years.

In this century, 25 UK officers died in the line of duty. The figure for the US, 2445, is nearly one hundred times that. Adjusting for numbers of officers, US deaths are still ten times higher.

My guess is that what accounts for much of the UK-US difference is guns. Most British cops don’t carry guns. Last August, I posted (here – it’s gotten over 25,000 page views ) a video of a berserk man wildly swinging a machete in a London street. The police come, armed only with protective shields and truncheons. Eventually, they are able to subdue the man. In the US, it’s almost certain that the police would have shot the man, and it would have been completely justifiable. More cops with guns, more cops killing people. 

But more civilians with guns, more cops getting killed. Since 2000, six UK cops have died from gunshots; in the US, 788.  We have 11 times as many cops, but 130 times as many killed by guns.***

(I did not include the yearly data for the UK since it would not have been visible on the graph. In most years, total cop deaths there ranged between 0 and 2.)

Thanks to the ceaseless efforts of gun manufacturers and their minions in legislatures and in the NRA and elsewhere, US cops work in a gun-rich environment. They feel, probably correctly, that they need to carry guns. If that man in London had been wielding an AR-15 (easily available in many states in the US – in the UK, not so much, not at all in fact), the cops could not have responded as they did. They would have needed guns. There would probably have been some dead civilians, perhaps some dead cops, and almost certainly, a dead berserker. 

----------------

* We don’t have a good source of data on how many people the police kill.  (See this WaPo article.) An unofficial source since 2013 is KilledByPolice.net. The data on killings by the UK police is also not precise. Politifact (here) says that the Wikipedia numbers that the Kos article is based on are “far low, but we don’t know how low.” PolitiFact does suggest that many of those killings by police were not by London Bobbies. They were by the R.U.C in Northern Ireland during the “Troubles” with the I.R.A.

** The denominator for the UK – the number of police officers over the last 115 years  – is my own very rough estimate.

*** The other two leading causes of police deaths are heart attacks and car accidents. Maybe UK cops practice better cardio fitness. But they also spend less time patrolling in cars, and they are less likely to be chasing other cars on the highways.
