Seven out of 10 citizens living in the South Korean capital of Seoul favored reunification with the Democratic People's Republic of Korea (DPRK), a poll showed Wednesday.

According to the survey of 2,000 Seoul citizens aged 19-64, 74.2 percent said the reunification of South Korea and the DPRK is necessary. It was the same as last year's poll.

The poll was conducted by the Seoul Metropolitan Government from Nov. 25 to Dec. 3. It had plus and minus 2.2 percentage points in margin of error with a 95-percent confidence level.

Those in their 40s preferred the reunification most with 78.6 percent replying that the reunified Korea is necessary. The lowest rate of 66.0 percent in favor came from those in their 20s.

The Korean Peninsula has been divided since the liberation from the 1910-45 Japanese colonization. The two Koreas remain in a technical state of war as the 1950-53 Korean War ended with armistice, not peace treaty.

Asked about when the reunification could be realized, 25.6 percent said it could come true within 20 years, followed by 20.2 percent predicted the reunification within 30 years. Those who said the reunification would be impossible was 17.0 percent.
