I find it interesting that they had to rely on data volunteered by a grocery chain. They should build in something to the SNAP card system so they can track at high level where the money is being spent. That could provide some interesting data about nutrition and budget of the low income population.

- tomnipotent 10y agoA single nation-wide grocery chain should be enough to establish trends - that's how statistics work. The report is looking at broad categories of foods (soft drinks, vegetables). Walk into any Kroger, Whole Foods, Von's, or Trader Joe's and you'll the same assortment of products at similar levels of inventory. Demand shifts take many years and even decades, and grocers use that data very effectively for inventory control management. Even without controlling for multiple chains, I'd wager the numbers are in the ballpark of the expected value.
