esp if they are only based on statistics for REPORTED rapes.
I think we'd all like to believe society has changed--that it is less acceptable to rape women. And hopefully more women are not as naive --and are not confused about what rape is or isn't anymore. But they may not even be reporting it as much as in the past, a by-product of their taking more responsibility for their own sexuality. As for the relationship of pornography to rape, you would need to fully research that topic beyond making assumptions based only on statistics.
In this WAPO article from 2006, you can see how the debate is still very open on this question of whether rape rates reflect a true reduction in the crime:
Excerpt (snip)
"By all accounts, rape is still one of the most underreported crimes. Several decades after the establishment of rape crisis hotlines, greater sensitivity toward rape victims by police and prosecutors, adoption of policies by news organizations to not identify victims and limitations on how much a victim's sexual history can be placed in evidence during trial, the Justice Department estimates that
61 percent of rapes and sexual assaults are still not reported. But that is down from 69 percent in 1996, and experts say the trend remains downward.
Not everyone is convinced that things are getting that much better. Many who work with rape victims say they do not believe there has been a widespread decline in the number of attacks. Instead -- despite the years of attempted outreach to rape victims -- they say the crime may be as hidden now as ever.
"If there's been a change, it's been a very small change," said Dean Kilpatrick, director of the National Crime Victims Research and Treatment Center in Charleston, S.C. He said that recent high-profile rape cases such as those involving Duke University lacrosse players and basketball star Kobe Bryant may have persuaded rape victims to stay silent because of public scrutiny of the accusers' private lives and sexual history."

And from the same article:
"In the Washington area last week, local officials said they had seen little evidence of a vast decline in rape. Last year, the District's total rapes fell 24 percent; at the same time, reports of rape increased in several suburban jurisdictions.
Because the recent federal report on crime statistics counts only cities, statistics on other local jurisdictions were not included."I think we're steady in Prince George's County," said State's Attorney Glenn F. Ivey. He said county authorities have seen new and disturbing trends in sexual assault, including a spate of attacks by juveniles and a few assaults committed at school-day "skip parties." Ivey recalled one recent skip party at which a girl was allegedly surprised and attacked by eight or nine men as a kind of gang initiation. "I just don't recall seeing things like that 10 or 15 years ago," Ivey said.
