They each have multiple meanings and the meanings overlap. One common use of "region" is "a part of the world with a fairly clear boundary," not corresponding exactly to any governmental unit. It might be a familiar region with a well-known informal name, or it might be an arbitrary region that's being described as it's being discussed. For example, "I live in the New England region of the United States. My wife grew up in the Midwest region." There isn't any formal or official definition of these regions, but each has somewhat similar climate, history, and traditions. "Would you like a glass of tonic?" "Tonic???? You must be from New England. I call it 'pop.'" "Oh, you must be from the Midwest." "Thunderstorms will be moving through the eastern region of the state this afternoon." "Piedmont Airlines isn't a big international airline, it's just a small regional airline serving the Pennsylvania region." "Linda West is Vice President of Sales for our EMEA Regional Division." It can also mean "a portion of something with a fairly clear boundary." "There seems to be cold air coming into the house somewhere in the general region of the basement." We don't know where it is exactly, but it's in the basement, not the first floor, second floor, or attic. "Area" can often be used in place of "region." "Region" is one of the meanings of "area." However, you can't do it the other way around. In the following examples, you could NOT say "region." "Area" can mean the measurable size of a surface. "The area of Australia is 7.6 million square kilometers." "Area" can mean a field of competence or study. "My area of expertise includes the C and C# programming languages."

A "region" is always large, while an "area" can be small or large. You can say, for example, "people in the northern region of the country all wear furry hats," but you could also say "people in the northern area of the country all wear furry hats." On the other hand, you can say "I try to always keep this area of my house clean," while you can't say *"I try to always keep this region of my house clean."

area is defined by acreage ; religion is related to humans who live in groups of race or majority
