Is This Actually Based On Evidence?

According to this story on recent struggles at Wal-Mart, "The average Wal-Mart shopper lives in the suburbs, is roughly 5-foot-2 and wears a size 14 — making them poor candidates for the skinny jeans that were a popular, tight-fitting fashion in urban markets." Is there any actual evidence to support this claim or is this the writers just throwing some shit on the page? Even if we're talking about women here, I don't think the average Wal-Mart shopper is 5'2. Or maybe Wal-Mart caters to short people. Considering that in New Mexico, 5'2 is significantly above average for a woman, maybe there's something to it. A size 14? Maybe but I don't know. And I don't think the writers do either.

Stuff like this isn't really that huge of a deal in the big scheme of things. But it shouldn't be in any story published in a major newspaper either.
