You know what they say...

Hey, does anybody happen to know the answer to this question?

Back when Mr B and I started doing joint grocery orders, I started analyzing our budget like you do. In the course of doing so, I discovered something I hadn't realized: about a third of my "grocery" budget wasn't food. It was:

• Disposable food handling and storage supplies: plastic wrap, paper towels, aluminum foil, ziplocs, e.g.

• Personal hygiene supplies: toilet paper, bath soap, shampoo, skin lotion, menstrual supplies, toothpaste, mouthwash, Q-tips, e.g.

• Health supplies: vitamins, bandaids, NSAIDs, first aid supplies, OTC medications and supplements, e.g.

• Domestic hygiene supplies: dish detergent, dish soap, dish sponges, Windex, Pine-sol, laundry detergent, bleach, mouse traps, e.g.

None of these things individually needs to be bought every grocery trip, but that's good, because they can add up fast. Especially if you try to buy at all in volume to try to drive unit costs down. But the problem is there are so many of them, that usually you need some of them on every order.

This fact is in the back of my head whenever I hear politicians or economists or social commentators talk about the "cost of groceries": I don't know if they mean just food or the whole cost of groceries. Sometimes it's obvious. An awful lot of the relief for the poor involves giving them food (such as at a food pantry) or the funds to buy it (such as an EBT card), but very explicitly doesn't include, say, a bottle of aspirin or a box of tampons or a roll of Saran wrap. Other times, it's not, such as when a report on the cost of "groceries" only compares the prices of food items, and then makes statements about the average totals families of various sizes spend on "groceries": if they only looked at the prices of foods, does that mean they added up the prices of foods a family typically buys to generate a "grocery bill" which doesn't include the non-food groceries, or did they survey actual families' actual grocery bills and just average them without substracting the non-food groceries? Hard to say from the outside.

When we see a talking head on TV – a pundit or a politician – talking about the price of "groceries" but then say it, for example, has to do with farm labor, or the import of agricultural goods, should we assume they're just meaning "food" by the term "groceries"? Or it is a tell they've forgotten that not everything bought at a grocery store (and part of a consumer's grocery store bill) is food, and maybe are misrepresenting or misunderstanding whatever research they are leaning on? Or is it a common misconception among those who research domestic economics that groceries means exclusively food?

So my question is: given that a lot of information about this topic that percolates out to the public is based on research that the public never sees for themselves, what assumptions are reasonable for the public to make about how the field(s) which concern themselves with the "price of groceries" mean "groceries"? What fields are those and do they have a standard meaning of "groceries" and does it or does it not include non-food items?

This question brought to you by yet another video about the cost of groceries and how they might be controlled in which the index examples were the ingredients for a peanut butter and jelly sandwich, but, as usual, not the sandwich baggy to put it in to take to school or work.
