It seems all that pressure from concerned parents around the country gave the MOGEF, along with other related government branches, the proper funding it needed to do a more comprehensive survey. The scope of the study on internet addiction greatly expanded from the 2010 survey in terms of the age range and sample size. In 2010, the government studied people aged 9 to 39 years, with a sample size of 7,600 people. In 2011, the ages went from 5 to 49 years, and the sample size increased to 10,000 people.
Overall, the rate of internet addiction has dropped from 8.0% to 7.7%. However, for those at "high risk," the rate has increased by 0.3%. The government reports that normal folk who use the internet check for news articles and other information (43%), while internet addicts typically used the internet to play online games (41.3%). They throw a bunch of other numbers around, and the verdict they reach is that gaming is linked to internet addiction. The government will use these results to establish education about internet addiction as well as preventive measures.
You can download the results of their survey at their website. The report is written in Korean, and you'll need a program that can open .hwp files. You'll find that it is rather brief (nine pages in all), and I can't say I find the survey wholly accountable. It's kind of a slapdash effort, and it bodes ill for gaming in Korea, but I have to admire the ingenuity behind MOGEF's method to expand their influence.
