A confidential analysis of Internet search queries and a random sample of Web pages taken from Google and Micrsoft's giant Internet indexes showed that only about 1 percent of all Web pages contain sexually explicit material.
The ACLU said the analysis, by Philip B. Stark, a professor of statistics at the University of California-Berkeley, did not appear to substantially help the Justice Department in its effort to prove that criminal penalties are necessary to protect minors from exposure to sexually explicit information on the Internet.
One percent? I don't know where they got that number from, but the percentage is way higher on the Internet I am using.
