The Programme for International Student Assessment (PISA) ranks Mexico in one of the last places in science performance [OECD, 2019]. This has been a concern for some local science communication groups (SCGs) in small and medium-sized cities, whose mission is to fill this disparity by performing science communication (SciCom) activities. The SCGs were contacted via a survey to collect information about their dynamics and public reach. A descriptive analysis enabled the identification of the logistics and coordination issues found among SCGs. Consequently, a local network of science communication groups is advised to reinforce their impact.
