A survey of users of the Internet in 1995, when Internet use was much less common than now, found that males outnumbered females by nearly 2 to 1. This was a surprise because earlier surveys had put the ratio of men to women closer to 9 to 1. Later in the article we find this information: "Detailed surveys were sent to more than 13,000 organizations on the Internet; 1,468 usable responses were received.
