What's with the grey states? Are their no Catholics in Alabama and Utah? Did they run them out of those states?
That means that there was not a significant enough amount to present an accurate sample.
In North Dakota, though, there were actually no Jewish respondents whatsoever.
Another reason why I am never moving to Utah.
This is not because there are no Catholics; it is just because there are so many Protestants that it does not matter.
You'll notice states like Washington have samples for thinks that only consisted 5% of the respondents while some states lack respondents for 8% groups. This is because battlegrounds and semi-battlegrounds like Washington were polled more closely than other states.
