The grocery data makes no sense. Detroit has a median income of 40k and spends 3.78% on groceries? So that’s $126/month? How can that be true?
Looking at the methodology it seems like what it actually calculates is a fixed food basket compared to median income (so the specific number is arbitrary). But higher earning areas tend to buy more expensive items so in practice the difference will be less.
I don’t know why they didn’t just look at actual spending on groceries in each city?
