This study examined the link between accessibility of electronic gaming machines (EGMs) and the socioeconomic status of neighbourhoods in Helsinki, Finland. It also examined whether EGM spending is linked with EGM accessibility and the socioeconomic status of neighbourhoods. Accessibility was measured in terms of density of and distance to EGMs. This study used two databases: (1) socioeconomic status (SES) of the adult population, obtained from Statistics Finland, and (2) player account-based gambling data, provided by Veikkaus. The analysis included data on 71,669 adults who gambled on EGMs, 745 EGM venues, and 2,397.1 EGMs. The findings suggest that EGMs are more accessible in neighbourhoods with lower SES. The annual losses per adult are also higher in those neighbourhoods. In other words, people living in the most disadvantaged neighbourhoods live closer and lose more money to EGMs, especially to machines close to their homes.
