Affiliate Marketing Secrets

I don’t have any particular religious affiliation here, but I’d like to know if the majority of the world’s charities are affiliated with the Christian faith. Is there any way to know the answer to this question?

an applicant’s religious beliefs? Are they allowed to advertise as such, even requiring an applicant to prove religious affiliation? If there is a law, what is it exactly? If not, how do they get away with it? Is there anything that can be done about it (e.g. file a civil rights complaint)?

I was born and raised Jewish, and my family goes to a Reform temple. We aren’t very religious but I’ve found myself becoming more involved in my temple as I’ve gotten older. I don’t plan on being extremely observant in college but I’d like to have the option of going to temple.
I’m a junior in high school so I’ve been looking at colleges. I’ve been discounting a lot of colleges, both public and private, on the basis of religious affiliations.
Obviously Judaism is a minority religion in the U.S., so I haven’t found many “Jewish” schools. Should I still look at schools affiliated with Christianity or am I doing the right thing? I’m not really sure how much of an impact a religion will have on the college and campus life.
Thank you!

the American Physical Society –
The team took census data stretching back as far as a century from countries in which the census queried religious affiliation: Australia, Austria, Canada, the Czech Republic, Finland, Ireland, the Netherlands, New Zealand and Switzerland.
“in a large number of modern secular democracies, there’s been a trend that folk are identifying themselves as non-affiliated with religion; in the Netherlands the number was 40%, and the highest we saw was in the Czech Republic, where the number was 60%.”
A recent poll showed that only 14 percent of Canadians think that God created humans in their present form within the last 10,000 years.
I don’t think America is becoming more religious. As a college student who knows many people across this country at institutions of higher education, most of them don’t believe in a god. As these younger generations grow up and make it into political office, religion will decline in civilized areas even more. I guarantee I’ll see the first president of this country who puts agnostic (or hopefully atheist) as their religious belief rather than Christian.
According to a 2007 Pew poll, the number of “non-affiliated” Americans was 16.1%, up from 8% just one decade before. This number is nearly 25% in the under 25 age group. And 55% of those who self-identify as “atheists” are under 35. So yes, the trend is that America is getting less religious and more and more young people in particular are turning away from religion.

I’m researching schools that are private, and have no religious affiliation in Southern NE. RI, MA, and CT are the states that I’m looking at. Thanks in advance!
Also post your opinions about them, especially if you are a student there!
