In what ways are the regions culturally different due to religion?

Different regions are more influenced by different religions based on where they are in the world. Climate, agriculuture and many other factors also can change how regions are culturally different due to religion. Some places are more religion dependent while others are not. I live in one of the biggest cities in the united states and if you don't want religious influence, you by no means have to have it. But meanwhile my grandma lives in a town that only about 1,000 people live and religion is everything to them.
