Visualizing North Korean ‘Provocations’: A Timeline

By Matt Stiles | | Topics: North Korea, South Korea

Until the recent incident involving a defecting soldier, tensions between the United States and North Korea had cool slightly, largely because the communist regime hasn’t committed any so-called “provocations” — ballistic missile and nuclear tests — in more than two months.

Under the North’s young leader, Kim Jong Un, such incidents have increased significantly as his nation seeks to improve its ability to strike targets with nuclear weapons. That effort has included dozens of ballistic missile tests and four underground nuclear detonations during his tenure, which began in late 2011 after the death of his father, Kim Jong Il.

This timeline, inspired by a graphic made by the NPR Visuals team, shows these provocations since 2006, when the regime tested its first nuclear weapon:

Common Ground Between North and South Korea: Aging and Shrinking Populations

By Matt Stiles | | Topics: Demographics, North Korea, South Korea

The birth rate in South Korea, where I live and work, hit a record low this year, leading to concern about the impact an aging (and, eventually, shrinking) population might have on the nation’s society and economy.

These charts show the long-term trends, both in actual population and projected changes, according to United Nations data. I’ve added North Korea, which actually has a higher fertility rate today, for context.

First, let’s look at the populations of the two countries, which share an ethnic background and a (mostly) common language — despite the Korean War-era division of the peninsula.

South Korea has about 51 million residents, roughly twice the number of people in the North, which has 25 million. That’s the number of South Koreans who love in the Seoul metro area, by the way.

Both populations are expected to peak in two decades — and then begin to decline.

That downward trend, for now, is much more pronounced in South Korea because of the nation’s low birth rate. Having a large family in South Korea, where housing and education costs are pricey, isn’t possible or practical for many people. The nation also has relatively weak maternity leave policies (and stubbornly traditional gender roles in the home and workplace), leading women to postpone childbirth to pursue their careers.

South Korea is slightly smaller geographically (about the size of Indiana, in terms of area) than the North (roughly the area of Pennsylvania). So their respective population densities vary, too:

Here’s how South Korea has grown, in five-year-increments, since 1950 — when the Korean War began and ultimately changed the trajectories for both countries. South Korea saw relatively rapid growth rate immediately after the war, perhaps as refugees resettled. Projections show that rate declining by 2035:

The North experienced a rapid decline during the war, mostly likely from the death toll during the conflict, the political purges that followed — and the southern migration before the border was secured. Its growth rate soon recovered, however, but could begin declining again by 2045.

Here’s hoping the Korean fertility rate rebounds, or the two nation’s unify — or either becomes more welcoming and accommodating of immigrants. At things stand now, South Korea could become “extinct” by 2750 — a worrying (though simplistic and imperfect) simulation for a uniquely homogenous society that traces its roots back thousands of years.

Visualizing South Korea’s Assailed Trade Relationship With The U.S.

By Matt Stiles | | Topics: Economy & Finance, Policy & Politics, South Korea

President Trump isn’t happy with the United States’ bilateral trade agreement with South Korea.

His main concern, it seems, is that the United States has suffered a “trade deficit”. That means South Korea — a key ally in East Asia on security issues, not just trade — has been exporting more goods to the United States than it has been importing.

In 2016, this deficit was about $23.2 billion.

That’s a big figure, but the United States has a big economy. In context, it’s not much.

Before we get to why that matters, here’s a look South Korea’s trade balances with the world’s largest economies last year. It had surpluses with China ($37.5 billion), its main export customer, Hong Kong ($31.2 billion) and the United States ($23.2 billion), among others.

It had trade deficits of its own with some economically powerful countries, by the way, most significantly Japan (-$21.3 billion), Germany (-12.4 billion) and Saudi Arabia (-$10 billion). Take a look:

It’s important to note that trade balances sometimes vary based on the products each country sells and each country’s relative slice of the global economy, not necessarily trade agreements in their early stages. (China is an exporting powerhouse that sells mass quantities of cheap goods to almost everyone. Saudi Arabia, on the other hand, sells pricey oil. The nature of that trade is already imbalanced).

It’s also critical to think about each country’s balance in the context of its overall trade with South Korea.

The United States has that $23 billion deficit, as Trump and others in the United States have noted recently. It imports about $66.4 billion from South Korea and exports about $43.2 billion. A key departure point is automobiles. (You don’t see many American cars on the roads here in Seoul, where I live). Regardless of why, the deficit represented about 21 percent of the overall trade in 2016.

That’s a significant (and growing) figure, but how does it compare relative to other countries?

When normalized, Egypt, Hong Kong, Turkey, Poland, India, Mexico, Belgium and Norway had more unbalanced trade relationships with South Korea than the United States did last year.

Here’s a look at South Korea’s various trade balances with the world’s largest economies, over time, as a percentage of each nation’s overall trade relationship. While South Korea enjoys a trade surplus with the United States, it’s relatively modest in the context of the overall volume — on par with Brazil, China and Thailand, for example.

I’m not saying Trump is wrong to worry about whether the United States has an equal trade relationship with this one trading partner. There’s just a piece of the picture, perhaps, missing from the discussion — even before you consider whether picking an economic fight with a regional security ally is smart policy right now.

Visualizing North Korea’s Missile Launches

By Matt Stiles | | Topics: North Korea, Policy & Politics, South Korea

Despite international objections, North Korea has launched four ballistic missiles in the last week, including one that flew over Japan, raising regional tensions about the rogue state’s weapons development even higher.

For those of us who live in South Korea, such provocations have become commonplace, especially since the North’s new leader, Kim Jong Un, took over after his father’s death in late 2011. They interrupt Sunday breakfasts or even national holidays, but they haven’t yet seemed like a real threat.

(Of course, they can just use their ample artillery along the border to strike Seoul, where I live).

The missile testing pace and the North’s increasingly technically ability have increased significantly in the last years, however, causing more and more heartburn in the region.

This chart shows the pace of testing over the years, including missiles that “failed” in flight:

The North has over the years developed (and borrowed) its own set of missiles, each with varying capabilities. Lately they’ve grown more powerful, though not always reliable.

Here’s how often they’ve used them, by missile type:

Since 1984, there have been at least 115 missile launches. But those tests have come from a select group of locations around the North: airfields and testing sites. Here are those tests locations, aggregated, with larger bubbles representing more launches:

And this map shows each launch in time order, with a flurry beginning in 2013. Colors change based on the missile type:

Charting North Korean Provocations. A Case of ‘The Mondays’?

By Matt Stiles | | Topics: News, South Korea

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):

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):

Mapping South Korea’s Total and Foreign Populations — by Municipal District

By Matt Stiles | | Topics: Demographics, South Korea

South Korea, my adopted home for almost two years, has about 50 million residents as of the last census, in 2015. Most of them are settled in the country’s urban areas. About 22 million residents, for example, live in Seoul, the capital in the country’s northwest corner, and its adjacent province, Gyeonggi.

As an experiment to create a choropleth map with D3 and NPR’s dailygraphics rig, which drives most of the visualizations here, I’ve mapped the total population by municipal districts. In this example, Seoul is outlined with red:

I am, of course, not a citizen of South Korea. I’m a “foreigner” — as we’re referred to here. This is where the 1.3 million foreigners — many of them ethnic Koreans who immigrated from China — have settled across the country. Again, Seoul is outlined with red:

And this map shows the roughly 330,000 foreigners living in Seoul proper. This time I’ve highlighted Yongsan-gu, my home district in the city center:

Visualizing World Alcohol Consumption: What Beverages Do Countries Prefer?

By Matt Stiles | | Topics: Demographics, South Korea

I posted recently about how countries consume different amounts of alcohol — and how some have wider gender gaps when it comes to booze.

The previous posts relied on two data sets from the World Health Organization, which calculates consumption (in liters and grams) based on surveys and actual import, exports and sales data. The organization, a reader noted recently, also breaks down the consumption totals proportionally by beverage.

This chart shows each country and its relative tastes for beer, wine, spirits and “other,” which, in South Korea at least, is mostly soju, a fermented rice beverage that’s not easily categorized.

Visualizing World Alcohol Consumption: How Much Does Each Country Drink?

By Matt Stiles | | Topics: Demographics, South Korea

A few weeks ago I posted about gender gaps in alcohol consumption around the world.

In some countries — South Korea, for example — men and women consume quite different amounts of booze, according to the World Health Organization. Fueled by a love for soju, South Korea’s men are among the heaviest drinkers in the world, consuming about 78 grams per day — nearly twice as much as other men on average. Its women drink only slightly more than their counterparts abroad, on average.

But that data only averaged daily consumption, by country, among people who list themselves as “drinkers”. The organization also has estimates about per-capita consumption amounts based on countries’ import, export and sales data, normalized with their adult populations. Depending on your question, that might be more useful information.

Those data, which also offer a breakdown of alcohol types (beer, wine, spirits and “other”), tell a different story. Instead of leading the world, by that measure South Koreans rank farther down a list of 196 countries: 35th.
