Jimmy Buffett uses his amassed fortunes to give to a variety of causes around the country, but primarily in the South.

"Singer-songwriter Jimmy Buffett is likely best known for "Margaritaville," a 1977 song that was inspired by a drink he discovered in Austin, Texas. Buffett has moved all around the South over the years. He was born in Mississippi, and has lived in Mobile, Nashville and Key West, among other places. This explains why a lot of  Buffett's philanthropy has focused in on the Southern United States.

"Before we continue, though, I should mention that Buffett also owns restaurant chain Margaritaville, meaning that he's amassed wealth in a number of different industries. Some estimate his net worth at around $450 million."--Ade Adeniji, Inside Philanthropy
