I find it amazing from the National Geographic survey that the Hispanic migration into my home state of Georgia has increased the Catholic percentage from 3.0 to 10.9% over the past 30 years. And California from 23 to 33%. And Massachusetts jumped from 17 to 41% in the same period?!!
Massachusetts hasn't had THAT much immiigration in the last 30 years, even counting Irish and Eastern European immigrants. there has to have been a flaw in the counting methodology in one of those years (and considering their claim only a seventh of mid-80's Massachusetts was Catholic, my guess would be the 85 numbers were off).
