LOS ANGELES (CBSLA) — A local data firm has put together a crowdsourced map that shows how consistent certain ZIP codes are when it comes to wearing face masks.

The map from Infogears gathers self-reported data for ZIP codes across Southern California to give a 60-day snapshot of respondents’ symptoms, how often they left home, and their mask usage.
