According to a survey released on the 15^th by the China Internet Information Center (中国互联网络信息中心), 79 million Chinese are internet users. A year of steady growth has seen an increase of 34.5% over last year's count. This puts China second on the list of countries ranked by gross number of people online. Other interesting statistics:

The number of people with computers has grown to almost 31 million, a 48.3% increase over last year. This shows the large number of people that use China's ubiquitous internet cafes to get online. This year's numbers, though, show the percentage of internet cafe users shrinking as families purchase computers for their homes and businesses.
There are 595,990 registered domain names in the .cn TLD.
The number of broadband users has increased by 7.6 million over the past six months.
Outbound bandwidth has increased 1071 times over the level of 1997.

Interestingly, the last paragraph of the survey summary mentions that the CNNIC collected data on IPv6 adoption but doesn't say what the results were (the full results are available in a large pdf file). IPv6 is the next generation of internet addressing that promises to increase the number of IP addresses to an insanely huge amount, one that—theoretically—will never be exhausted. A Xinhua News Agency report on the survey points out that: 然而统计报告还显示，我国的IP地址资源近几年虽有较快增长，但仍不能完全满足中国互联网络运营单位发展的需要。随着我国网民人数的大幅增加，网络应用的逐步加强，IP地址发展与互联网络发展的不匹配性会显得更加突出。 --In other words, the report says that China is using up IP addresses so quickly that the current availability will soon be insufficient; as the number of internet users increases, the issue of IP address availability will become more pressing. This is an interesting prospect for the growth of IPv6. The technology has been slow to catch on in the United States, which holds the rights to a very large number of IP addresses, and as such the need to upgrade has not been so urgent. The Xinhua article also has a couple more interesting things to say. It spends a couple paragraphs pointing out the problem of the "digital divide" that exists within its borders; internet use and internet technology has developed much more rapidly and to a greater degre in coastal areas than in central and western China. It also goes on to point out that, percentage-wise, internet use in China is still less than a tenth of the level reached in the United States, 6.2% vs 63.2%. These last two notes give the article a sense of balance that is sometimes missing in Chinese reporting. --The China Digital News weblog covered this story, including a link to an article in English from the China Daily.
