【正确答案】Internet Users in China by Age
The graph shows changes in the age profile of Internet users in China between 2006 and 2007.
The main users of the Internet in China are young adults between 18 and 30. In 2006, they accounted for 56.3% of all users. In 2007 the number dropped significantly to 51.3%, yet they were still the biggest group.
The following facts may explain the significant drop. The number of children online increased slightly from 17.1% to 18.8%. Meanwhile, the number of users aged between 31 and 50 increased from 23.7% in 2006 to 26.1% in 2007. There were similar increases for older users, rising from 2.9% in 2006 to 3.8% in 2007.
In sum, while adults between 18 and 30 still represent the majority of Internet users in China, their share is declining as more children and older adults join the web.
