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.

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?

Unfortunately, we don't have longitudinal data on foreigners' counties. But we can show the proportion of foreigners in Korea's major geographic administrative units — its provinces and autonomous large cities. And with the added dimension of time, you can notice major changes in the last two decades.

The capital city, Seoul, for example, now only has about a quarter of the country's foreigners, according to data released by the Korean Statistical Information Service. That's down from 52 percent in 1992. Many appear to be settling in Gyeonggi-do, the nation's most-populous province (it surrounds Seoul).


LOCATION & TIME

Here's a stacked area chart (mobile users see table below) showing the trend:

GENDER, LOCATION & TIME

Adding gender shows some slight differences, especially that Seoul has about 30 percent of female foreigners, compared with 20 percent of their male counterparts.

Mobile users, apologies. I'm hoping to launch a new site soon with responsive data tools. Until then, I'll try to add tables and other accessible graphics for quick posts like this. Not perfect, I know, but it's slightly less of a fail:
