Religion

America is one of the most religiously developed nations in the world, despite the fact that its governments uphold the principle of separation of church and state. Even if organized religion is on the decline in the US, this is reflected in day-to-day living there. Individuals can practice their religion freely and openly in American society.

Around 70–78% of individuals in the USA identify as Christians.
