Anecdotal evidence: Flushing, Elmhurst, and Jackson Heights are 3 densely populated working-class immigrant neighborhoods in Queens, NYC. In my personal observation, in Flushing (which has a large Chinese population) average people on the street and in grocery stores started wearing masks since February. In Elmhurst and Jackson Heights (large Latin American and South Asian populations) there were no masks in sight until maybe April. The rate of Covid infection in Elmhurst and Jackson Heights is ~50% higher than in Flushing.
