Charting South Korean Attitudes About Park Geun-hye’s Impeachment

By Matt Stiles | | Topics: News, South Korea

It’s been a busy few days of reporting in South Korea.

The scandal-plagued president, Park Geun-hye, was removed from office on Friday over a corruption scandal that has roiled politics and business in the country during the last six months.

Last night, two days after a court’s ruling to remove her, Park finally left the presidential complex.

The public overwhelmingly supported Park’s ouster, even if the disgraced leader wasn’t the source of all their concerns.

As one might expect, opinions about whether the former president should have been impeached vary by age and region. Here are the results of a recent survey by Gallup Korea.

First, age (the youth led the way):

And region (note that Daegu, in the southern part of the country, is Park’s home turf):

Charting NICAR Attendance, Over the Years

By Matt Stiles | | Topics: News

Next week is the Investigative Reporters and Editors annual CAR convention — the gathering of news nerds from across the world to discuss the latest and greatest in data journalism. This year NICAR, as its known among the nerds, is in Jacksonville, Fla.

After attending each year since 2006, I had to skip the convention in 2015 and 2016 because I now live in Seoul. But I’m making the long journey to Florida this year, and I wanted to know how many people would be there.

The fine folks at IRE graciously shared historical attendance data with me:

(I’ll be using this data, by the way, for our demonstration session on NPR’s dailygrapics rig — the visualization tool I use for this blog).

Happy Valentine’s Day, America: Charting Our Declining Marriage Rate

By Matt Stiles | | Topics: Demographics, News

It’s Valentine’s Day, a perfect time to note that the marriage rate in the United States has been on a steady decline for decades, save for a brief spike in 2012.

So romantic.

Here’s the rate per 1,000 people since 1997:

You can also view that rate by state. What’s up with you, Hawaii? (I’ve excluded Nevada, which skewed the axes for all the small multiples because of its freewheeling marriage culture). There are some interesting trends here, but most states remain relatively close to the national rate:

Here’s the 2015 marriage rate, by state, on a tile grid map:

How Common is Your Birthday? This Visualization Might Surprise You

By Matt Stiles | | Topics: Demographics, News

It’s baby season in America, with September the busiest month for births on average in the last two decades. So it seemed like the right time to remix this blog’s most-popular post: How Common is Your Birthday?

That old heatmap, which highlighted specific dates for popularity, has been viewed more than 500,000 times here and published across the web. But it was flawed, namely that it used ordinal data (birthday ranks by date) rather than continuous data (actual births counts by date). This graphic finally addresses that problem:

Editing O.J. Simpson: Charting Changes to His Wikipedia Page

By Matt Stiles | | Topics: Crime, News, Sports

I’ve just finished watching ESPN’s fabulous O.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.

Charting U.K. Immigration by Country

By Matt Stiles | | Topics: Demographics, News

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.

How Immigration is Animating the ‘Brexit’ Vote, in Four Charts

By Matt Stiles | | Topics: Demographics, News, Policy & Politics

Immigration to the United Kingdom has risen sharply in recent years, and it’s fueling the debate about Britain’s looming “Brexit” vote on whether to leave the European Union.

Many supporters advocating a “leave” vote on June 23 believe it’s best the best way to control Britain’s borders, which under E.U. rules have been opened to workers from other member nations.

The Brussels-based union has in recent years expanded to Eastern European nations, and residents from the those countries have flooded the U.K., population 64 million, newly released data shows. That’s stoked fears that the its traditions and values are changing. Others say the influx of outside residents keeps Britain’s economy relatively strong.

The U.K.’s Office for National Statistics tracks the ebb and flow of people each year. I’ve charted the figures ahead of the vote.

Air Quality in Seoul, China, U.S.

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:

Charting the Popularity of ‘Hillary’

By Matt Stiles | | Topics: Demographics, News, Policy & Politics

Despite her big win in New York, trouble looms for Hillary Clinton in the general election, according to a new poll that shows her favorable/unfavorable ratings at dangerously low levels among key demographic groups.

Clinton has seen her fair share of bad polls over the years, yet she’s found ways to rebound. The same can’t really be said about her first name, however.

Perhaps one measure of her favorability — if so, a cruel one — is the frequency with which American parents have decided to call their daughters “Hillary”. The name peaked historically the year her husband, Bill Clinton, won the White House. It then plummeted dramatically, according to Social Security card application data released by the federal government.

This chart shows the proportion of parents who picked “Hillary” since 1947, the presidential candidate’s birth year:

“Hillary” was most popular in 1992, when about 2,500 girls received the name — roughly .14 percent of those listed in the data that year. Two years later, only about 400 girls received the name, or about .02 percent. (“Hillary”, by the way, made a small but brief comeback in 2008).

The figures in both years seem low, given the size of the country. But remember that Americans get creative with their kids’ names. There were about 1.84 million girls who received Social Security cards in 1992, and their parents picked at least 15,000 different name iterations, from Aaisha to Zykeia. Ashley was most popular with about 38,000 applications (or roughly 2 percent of the listed names).

Perhaps Hillary would be slightly more popular if parents conformed (or could spell). In 1992, for example, a few hundred poor souls got these iterations of Clinton’s name: Hilliary, Hillery, Hillari, Hillarie and Hillaree. Also: Hilary.

My name — Matthew — has taken a roller coaster ride, too. It peaked in 1983, with about 50,000 boys receiving it — roughly 2.8 percent of the 1.8 million boys who received Social Security cards with that birth year. What caused the name’s rise? Perhaps I’ll never know, though my mother picked it not from the New Testament but from a John Denver song.

Thanks, Mom. (At least you spelled it correctly).

New Show, Knife Raise O.J.’s Google Profile

By Matt Stiles | | Topics: Crime, News

More than 20 years after his blockbuster murder trial, O.J. Simpson is back in the news — this time after Los Angeles police reportedly found a knife on the grounds of his former estate.

O.J. Simpson

O.J. Simpson

According to the Los Angeles Times, a retired police officer “has handed over a knife given to him by a construction worker who helped raze Simpson’s mansion in 1998.” The knife, which could have been used in the slayings of Nicole Brown Simpson and Ronald Goldman, is now being tested by the police.

The news comes a month after a new television show dramatizing his sensational trial began airing on FOX.

The renewed interest in Simpson, now serving a prison term in Nevada for an unrelated robbery and kidnapping case, is reflected in online search traffic, according to Google Trends.

This graph shows search volume since 2004. Traffic has been relatively dormant over the years except for spikes, like in September 2007, when Simpson was arrested in Las Vegas on multiple felony counts after an altercation over sports memorabilia. Another spike in late 2008 reflects his conviction at trial. He’s now serving out a 33-year-term but is eligible for parole next year.

Searches for his name spiked significantly after the new show, starring Cuba Gooding Jr., began airing Feb. 2.

Regional trends are also evident in the searches. This map shows that searches in Nevada and the Las Vegas metro area more common than in other parts of the country. That makes sense because of the location of his trial and incarceration.

Someday O.J. Simpson will no longer capture the collective imaginations of Americans. Today is not that day, apparently.
