Say 50,000-100,000ish people. When I lived in the US, I lived in a city of around 60,000 people. Local grocery stores often had small sections for food from most countries in East Asia, Latin America, and Western Europe. For instance I could get things like Ribena, Parmigiano Reggiano, or quince jam pretty easily. There were also often stores that specialized in only selling foods from a specific region like Eastern Europe or India, so even stuff like Tymbark drinks, kvass, kabanos, jelito, Kofola, ghee, duiran, curry leaves, or aloo bhujia were there if you knew where to look. I imagine they were less diverse and more expensive due to being imported, but these international foods were always an option. Meanwhile, I currently live in a city of around 100,000 people in Chile and access to international food is far more limited to things like US potato chips, soy sauce, instant ramen, or dry pasta. Import stores for food aren't really a thing either. What's the situation like for small cities in your country?
