Indonesia, the largest economy in Southeast Asia with vibrant economic growth, is a potentially tremendous market for personal computer products due to low ownership ratio. Despite robust economic growth, penetration of personal computer products in Indonesia is very low that gives us great opportunity for business growth here, Dell Indonesia Managing Director Catherine Lian told Xinhua. \"According to the latest data issued by IDC, personal computer ownership ratio in Indonesia was only 10 percent of total population,\"she said, citing the recent data issued by the International Data Corporation (IDC), an American-based market research, analysis and advisory firm specializing in information technology, telecommunications, and consumer technology. She added that 85 percent of personal computers sold in Indonesia will be lower end products that provide adequate capability with prices of below 400 U.S. dollars per unit. The more promising aspect for vendors planning to tap the PC market in Indonesia is the significantly increasing number of people in middle class-plus society, she said. \"Generally, the middle class-plus society has high disposable income and the ability to purchase consumer goods. That\'s why we are bullish and confident in Indonesia as the key country of growth in this region,\" Catherine added. Analysts estimated that the middle-class society in the country would grow 7 percent per year from currently 80 million people to 132 million people by 2020. Indonesia, the world\'s fourth most populous country, posted growth rate of above 6 percent in the last few years. It expects to gain 5.8 to 6.2 percent this year amid economic slowdown that batters its exports. Indonesia has \'demographic bonus\' that would significantly contribute to the country\'s efforts to pursue higher growth until 2025.
