Since this is more of a poll, I’ll move this to IMHO.
What about non-American Dopers? What are the main religions in your country?
Well, funny thing is I wasn’t talking about temple - when I went to the Mormon church in Gallatin growing up, it was still in infancy – literally, we were one of the first families there – and within I’d say 3 years, there was a larger Mormon population in town than Catholic. I don’t doubt that there are quite a few Catholics in the area, I just find it funny that JPII would be put in Hendersonville and be so huge considering how relatively small the Catholic population in Sumner county is (especially by comparison to Davidson County). JPII is quite a bit larger than Father Ryan, IIRC. Meh…not trying to start a debate, just sayin’.
As for the thing on the 18th – as long as someone remembers to bump the thread near the date so I will see it 
I will be bringing my husband and good times will be had.
Zoe – the Seventh Day Adventists also have their main publishing headquarters in Middle TN IIRC – it is by Rivergate Mall. Used to be, anyway. That’s another group that’s quite large in Sumner County.
I will point out that while I know a lot of people who make up the whole range from Fundamentalist Christian to Muslim to Hindi to Wiccan to Satanist – it is definitely a Baptist majority in this area – and that was just kinda my whole point.

I’ll post a more informative reply after lunch, if another limey doesn’t beat me to it.
I live in northeast North Carolina. Most here are Baptist, Methodist, or independent fundamentalist Protestant. I was raised a Lutheran, and I have to drive 40 miles to find a congregation.
When I was across the state line in Virginia (Hampton Roads area), Lutherans, Catholics, and Episcopalians were much easier to find. In Indiana where I lived most of my life, even more so, but there I could also find Mennonites and Amish.
You might find the book Public Religion and Urban Transformation by Lowell Livezey to be interesting, as far as urban areas are concerned.

People back in Buffalo never believed that the region was more Catholic than Salt Lake City was Mormon until I showed them the numbers from ARDA.
I’m interested in the location of clusters of religious groups in a region where another religion is dominant. For instance, there’s a large concentration of Missouri Synod Lutheran churches cutting north and south through the center of Niagara County in the otherwise extremely Catholic Western New York area. Jews are concentrated mainly in suburban Amherst and Williamsville, with some still living in neighborhoods in North Buffalo and the Delaware District.
Pittsburgh’s heavily Catholic. Around here, during Lent, every restaurant except the vegetarian ones offers a fish special and every other fire department has a fish fry.
Huh. Here in Houston, it’s primarily white Protestants, black Protestants (and rarely do the two mix) and latino Catholics. There are some enormous megachurches here, including Lakewood Church, which claims to be the largest church in the world. They meet in a 16,000 seat arena and pack it four times a weekend.
According to 2001 census, 33.9% of Torontonians are Catholic with 24.3% being Protestant.
From the same census, we have 355 (0.008%) Scientologists and 110 (0.002%) Satanists.
We don’t seem to be very religious but that just might be my impression since I’m not. The closest I get is church softball with some Baptist friends.
AFAIK, it’s mostly Catholic in the St. Louis area. Directly near us, there is a fairly large Jewish population, though I’m not sure how large the Jewish population is in the St. Louis area in general.
We live a few blocks away from a church of Scientology.
Otherwise, mostly Christians of various kinds.
How’s that cat doing?
It’s a liger. Pretty much my favorite animal. Bred for its skills in magic.
It’s mostly Baptists and Catholics here, with a significant minority of Pentecostals and Methodists. Most other sects of Christianity, and most other religions, for that matter, are barely represented. In my tiny home town (500 people), there are nine churches that I can name right off the top of my head. I said seven a couple days ago to someone, but I remembered a couple more later.
Rural Colorado, northeast corner.
We have 17 churches in a community of just over 14,000 people. About one-third of the population is Roman Catholic (large population of descendants of Italin, German and Mexican immigrants). Two large Baptist churches, equally large Lutheran congregations, signifant number of Mormons; respectably-sized Presbyterian and Methodist churches, half dozen independent congregationalist churches and a smattering of Episcopalians, Seventh Day Adventist, Jehova’s Witness and other spokes in the religious freak wheel. There is a handful of people who are openly atheist or agnostic (including a high school teacher who has to constantly fight for his job) but no Unitarian Universalist group yet.
The biggest churches in town are Catholic, Southern Baptist, Christian (Disciples, I think, unless it’s gone independent) and Assembly of God (mine). We do have about four other independent Charismatic churches also.
I grew up in a very rural part of Western PA. There were a good number of Catholics, with Methodists probably in second place. There were also very large number of “Christians.” (I use quotes because I have exactly no idea what word to use there, as nobody knew the exact name of the church. Nobody meaning me and anyone I’d ever asked.) There were many families, many of whom populated entire trailer parks a la compounds. They were quite fundamental - the women never cut their hair or wore pants, only dresses, married very young and raised very large families. They were very communal and distanced themselves from the rest of the population. They also traveled an hour and a half by car, twice a week, to attend services in another town. In my high school, with about 40 to 50 kids per grade, I’d say there were at least 20 fundamental Christian children per grade, most of them related as cousins, etc.
We were one of exactly three Jewish families.
I now live in Portland, OR, and the most common religion seems to be “nothing”. Hardly anyone I know is a member of organized religion except a few Seventh-day Adventists. There are quite a few alternative churches - non denominational; I’m unsure if Christianity is even a common thread. The three churches in my neighborhood all have somewhat generic names but nowhere do they say anything like “Methodist”, “Presbyterian”, etc. I think that since this is such a young, progressive town with many transplants, the “I go to church were my parents go, and their parents before, and their parents before” doesn’t work since their parents go to church 1000 miles away, and the opportunity to find one’s own path in church falls into play.
Give me some of your tots.
I live in Cleveland, TN, which is right in the middle of the Bible Belt and is also the home of the Church of God, the oldest known Pentecostal Christian denomination.
They take God seriously around here but, being atheist, I do not.
Mormonism is far and above the dominant religion here. Last I checked there were 27 Mormon churches listed in the phone directory, and more have likely been built since. About every two miles there seems to be a Mormon church. We also have a Mormon temple here. We have plenty of other churches, too, and they collectively outnumber the Mormon churches, but the Mormon churches by themselves are the most numerous.
