this sounds like not the US. in the vast majority of the US traditional markets/small groceries are effectively extinct and illegal to build new in a financially sensible way.
I don’t have enough data to give you an answer one way or another but this was New England and we have a lot of things that are common for us but weird for the rest of the country by dint of being where colonization efforts were good enough to be started and built up, but not so bad that they are worth replacing.
Examples include individual shops that used to be called markets which are not farmers markets or supermarkets, basements in all/most homes, and town halls being an expectation of normal governance rather than a newsworthy event
