The BLS doesn’t even list a double digit increase for “food away from home” at all this year. “Food at home” has been decreasing the past few months but remains up by almost 5%.
CPI is not the best measure and isn’t always 100% accurate but it’s not going to be off by double digits.
> The index for food away from home continued to rise, increasing 0.6 percent in
September. The index for limited service meals rose 0.9 percent in September,
the largest increase in the history of the index, which dates to 1997.
> Despite the September decline, the food at home index increased 4.1 percent over
the last 12 months. All six major grocery store food group indexes rose over that
span, with increases ranging from 2.6 percent (cereals and bakery products) to
6.3 percent (meats, poultry, fish, and eggs). The index for food away from home
rose 3.8 percent over the last year. The index for limited service meals increased
5.5 percent and the index for full service meals rose 2.8 percent over the last
12 months.
Of note:
> The index for used cars and trucks
rose 6.7 percent in September, its largest monthly increase since February 1969.
