Here's one PDF report I've found from the US Department of Justice: <https://www.bjs.gov/content/pub/pdf/fpcseo06.pdf https://www.bjs.gov/content/pub/pdf/fpcseo06.pdf> According to it, US federal attorneys dealt with 568 suspects of child sex abuse in 1994, and 601 in 2006. The chart shows the count remained steady-ish between those years. If we keep in mind that the US population was increasing, that means the rate of child sexual abusers being investigated has gone down. Over that time period, the rate of people investigated for child pornography drastically increased. This evidence does not support a casual relationship.
