The 2.8 percent fall in retail sales is the biggest single-month drop ever! Right? Not so much.
Here's the caveat most reports (but not all) aren't noting: "Ever" in this case dates back to ... 1992.
As a Commerce spokesperson told my colleague Terry Atlas, they rejiggered how they measure these things 16 years ago. So it's certainly a steep drop. CNNMoney says it could be the worst since a 6.5 percent drop in January 1987.
But "ever" is along time—certainly longer than 16 or 21 years.
