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.

South Korea’s Foreigners, Over Time

Yesterday we looked a the most-recent data on foreign residents in South Korea, breaking down their home countries and new locations.

But how has this changed over time?

Where are Korea’s Foreigners From?

Separating foreigners from the locals at a recent street festival celebrating Buddha’s birthday.

Note: My family last year relocated to Seoul, where my wife is working as a foreign correspondent for NPR. This post is part of an occasional series profiling the peninsula’s demographics and politics.

I had to move across the globe, but I’ve finally cracked The One Percent.

Not in wealth, of course. But I am one of about 24,000 civilian Americans living in South Korea, population 50.2 million. So that means I’m quite seriously in the minority. In my central Seoul district, for example, there are about 1,500 registered* Americans** — among 200,000 residents overall.

The country has just over a million registered residents from other countries, most of them from Asia. How does that foreign population break down by country, gender and province? These three treemaps help explain the distribution (mobile users, skip to the bottom of this post):

MEN vs. WOMEN
The foreign population here skews slightly male, perhaps because of the influx of Southeast Asian factory workers. In some parts of the country, however, the population skews the other way. In Seoul, for example, women from several countries — Indonesia being one — are more evenly distributed compared to the countryside, perhaps because city dwellers are more likely to hire domestic workers. Here’s a breakdown by gender and country (click the image for a larger view):

COUNTRY & PROVINCE/CITY
China, by far, sends the most foreigners to South Korea. That’s true for Han Chinese, but also residents who are the decedents of Koreans who at some point received Chinese citizenship. (The Korean peninsula shares a 800-mile border with China). The United States, to my surprise, if pretty far down the list of countries represented by foreign residents here.

PROVINCE/CITY & COUNTRY
The largest proportion of foreigners reside in Gyeonggi province, the country’s most populous state, following closely by Seoul. Together they represent close to half the country’s population — and most of its foreigners. But we are sprinkled throughout the country:

Larger, interactive versions of these treemaps, sketches in Tableau Public, can be viewed here: Gender | Country | Province.

They aren’t great on mobile, however. So here are two tables.

* The data come from an official source: The Korean Statistical Information Service. But it’s unclear what “registered” foreigners means — it’s not included in the metadata — and some foreigner totals differ.

** I live across the street from Yongsan Garrison, headquarters to the roughly 28,000 American forces stationed around the country. The troops there obviously aren’t included in South Korea’s immigration figures.

Charting Border Agents, Apprehensions

By Matt Stiles | | Topics: Policy & Politics

The U.S. Border Patrol told Congress on Tuesday that the number of apprehensions along the Mexican border was at a 40-year low. The trend prompted the agency to propose a new national strategy, the Associated Press reports:

For nearly two decades, the Border Patrol has relied on a strategy that blanketed heavily trafficked corridors for illegal immigrants with agents, pushing migrants to more remote areas where they would presumably be easier to capture and discouraged from trying again…. The new approach is more nuanced. Outlined in a 32-page document that took more than two years to develop, agents will now draw on intelligence to identify repeat crossers and others perceived as security threats, said Fisher.

This chart shows how the number of apprehensions has changed each year since 1925. The last time agents apprehended fewer people, Richard Nixon was in the White House (view larger version):

The number of apprehensions is down, experts believe, thanks in part to aggressive enforcement in recent years. This chart shows how the number of agents has increased substantially in the last 20 years (view larger version):

U.S. Naturalizations by Country

By Matt Stiles | | Topics: Uncategorized

The Department of Homeland Security now posts records detailing how many people become U.S. citizens each year, and from which countries. Visualizing this data on a world map is easy, thanks to Google Fusion Tables.

This map shades countries in darker greens based on the number of people who became citizens (excluding Mexico, which accounted for about one in five naturalizations in 2008, the most-recent data available): 

Here’s the view with Mexico:
