Good lord, don't do that. Every statistic, everywhere is biased, and slanted. Usually a party has a premise, and they go out to prove that premise is correct. It's just like with advertising, you wouldn't believe every commercial you see either?
We throw statistic around here, because that's sometime the only way we can make a point. But when you see who was behind getting the statistics, then you know. There are very few, unbiased reporting and survey agencies out there.
I'd say both pro-choice and pro-life sites have those very biased reports.
