Attention, Sinners: US 'Vice Index' Is a Little Low Which is actually bad news for consumer spending, says analyst By Matt Cantor, Newser User Posted Nov 6, 2013 2:48 PM CST 19 comments Comments The 'vice index' has hit a 17-year low. (Shutterstock) (Newser) – Brace yourself: Things are about to get tame. So says the vice index, which tracks spending on booze, gambling, and prostitutes: Its September reading was 104, the lowest it's been since February, the Wall Street Journal reports. The bad news may stretch beyond the realm of sin: It's a predictor of consumer spending four months in the future, says Andrew Zatlin of SouthBay Research, who developed the system. "It’s signaling that consumer spending growth is about to drop and stay subdued for a few months," notes the analyst, who's keeping quiet about just where he gets these numbers. That's not exactly great news for the holiday season.
