Religious Denomination Maps

[Alcon]

No religion? or No Organized Religion?

Non-religious.

Those without religion are estimated at 25% in Washington, and growing.  Roman Catholics are 20%.  The next is Lutheran, at 6% (generalised Protestants are at 29%, but that will probably fall below non-religious soon too).

Only 63% of Washingtonians identify as Christian, easily the lowest in the country that I can find.  So far, it's the only state I've found that is below 70%.

And then there's the consideration that a lot of those Christians never go to church and have no idea what their denomination stands for.  In reality, I'd wager that most people in Washington are "non-religious" in the sense that they don't practise their denomination of choice to any real extent.

I personally know very few religious people.  I'd say the vast majority of people at my school do not attend church even occasionally.

Do you know if there's any county that is majority non-religious?

The only survey to do by county and include non-religious people estimated the religious population at 50.03% countrywide, which is more like the religious population not belonging to a congregation.

The lowest rate for a county I've been able to find on that in a county reasonably large/populated to actually have its own churches is Ferry County, Washington, at 16.71%.  However, there could easily be people going to adjacent counties there.  The lowest genuine rate I've been able to find of a definitely self-sustained county is probably San Juan County, Washington's 17.15% - since San Juan County is entirely made of islands, after all.

Only one Washington county, Franklin, is above average in religious attendance; the only other to come close is Adams.  Both share one thing:  Hispanics accounting for about half the population.

According to those maps, I was once a Lutheran living in a county with no Lutherans. (Of course my family went to church in another county usually so we'd probably be counted there)

Yeah.

That's self-identification, not church attendance
