Jackson is still home to the Cowboy State's richest person. Christy Walton is on an updated list of the richest entrepreneurs in every state from gobankingrates.com. In 2015, a Walton was the richest woman in the world.

In 2017 that honor goes to French heiress Liliane Bettencourt of Paris, with a net worth of about $38.5 billion. If Christy’s worth is no longer near a dozen Oprahs, around $31 billion is still close compared to Ms Winfrey’s $3.2 billion in 2017.

Maybe you know Christy married Walmart heir John Walton, who died in a plane crash in 2005. Upon his death, Christy inherited percentages of about one-sixth of his shares in not just Walmart, but also Arvest Bank and First Solar.

Her son also inherited enough to become a billionaire.

It's no surprise that a low population and a high number of wealthy folks equals a median income overwhelmingly above average. See Wyoming's figures here.
