Population of Ulleungdo
Starting this year, the Uldo County magistrate, in accordance with an order from the Ministry of Interior, conducted separate surveys of the county's boundaries-position and household census. The total number of men was 1,916, the total number of women 1,616, and the number of households 614.
1906 Sep 26 - Boundary Survey of Uldo County Conducted
The article to the left appeared in the September 26, 1906 edition of the Korean newspaper, Hwangseong Sinmun (皇城新聞). The article mentioned that the magistrate of Uldo County (鬱島郡 - 울도군) had conducted two surveys ordered by Korea's Ministry of Interior. One was a boundary and position (境界位寘) survey of the county, and the other was a census survey.
The article gave the results of the census survey, but did not give the results of the boundary survey. However, a July 13 article in the same newspaper mentioned the boundaries of Uldo County when it reported on a response from Korea's Ministry of Interior to a request from the Japanese Residents General in Korea to clarify the islands belonging to Ulleungdo.
In its response, the Korean Ministry of Interior reported that the islands under the authority of Uldo County were Jukdo (竹島 - 죽도) and Seokdo (石島 - 석도) and that the boundaries were twenty-four kilometers (60 ri) from east to west and sixteen kilometers (40 ri) from north to south. This was the first time that boundaries for Uldo County were given since its incorporation in 1900.
The actual east-west distance from the western shore of Ulleungdo to the farthermost rock off its eastern shore is about fourteen kilometers, and the distance from the southern tip of the island to its northern shore is about ten kilometers. If the 1906 measurements were correct, then that would mean that the island had a sea boundary of about five kilometers around it.
This information is very important in the Dokdo-Takeshima debate because it shows that in July 1906 Korea's Interior Ministry and, apparently, the Uldo County magistrate did not consider Liancourt Rocks (Dokdo) to be a part of Uldo County since Liancourt Rocks is about ninety-two kilometers southeast of Ulleungdo and, therefore, outside the boundaries given for the county.
This article confirms that a boundary and position survey of Uldo County was actually done, rather than just using measurements from old documents.
Here is my translation of the Korean article:
