Read level comparisons as indicative, not precise. A market's basket cost reflects which items and stores cleared our sample thresholds there, not only genuine local price differences, and that composition varies between markets. The month-over-month change is the like-for-like figure — it compares the same items at the same stores, so composition cancels out.
Grocery price trend — Chicago, IL
Index level, August 2026 = 100
The line stops at the break on purpose. From August 2026 the item median is taken over distinct prices rather than every reading, so the index restarts at 100 instead of chaining through July — the step across that gap would measure the change of method, not a change in prices.
