In looking at the statistics released by Immigration for this post (regarding number of foreigners by visa type and region; look for 등록외국인 지역별 현황 on this page, released every June and December, and use the 지역별 및 체류자격별 tab at the bottom of the excel file), I also looked up the E-2 figures from June 2012. Here are the number of E-2s by region:
It'd be interesting to compare these figures to the more recent past to see which areas have been gaining and which losing (the number of E-2s peaked in 2010 at more than 23,000), though obviously the big decreases would be in Seoul and Gyeonggi. I'll save that for another day.
