Top 10% of singers revealed to make 89% of total singer income in Korea

The distribution of income among singers, just like the one among actors, has been revealed to be incredibly imbalanced.

According to the National Tax Service, 4,587 people filed their taxes as singers listed for their occupation in 2016. The top 1% - or 45 singers - made an average of 3.198 Billion KRW per person (approximately $2.7 million USD) over the year, making up 45% of the total singer income. The top 10% (458 singers) made an average of 640 million KRW per person (approximately $541,000 USD) over the year, making up 88.9% of the total singer income in Korea.

The rest of the 90% (4,129 singers) made an average of 8 million KRW per person (approximately $6,800 USD) over the year or about 670,000 KRW per person per month (approximately $570 USD). This is about 2/3 the minimum wage (of about 1,117,000 KRW per month, 5,580 KRW per hour).
