The data in the NBC News tracker, provided by NIQ, formerly NielsenIQ, is collected from real checkout prices paid nationwide at grocery stores, drugstores, mass merchandisers, selected dollar stores, selected warehouse clubs and military commissaries.

The Bureau of Labor Statistics’ monthly consumer price index, which uses human data collectors and includes other food product categories, is another resource for average price data.
