Abstract
This study examines the relationship between daily encounters with gambling facilities and gambling participation in a Czech region that transformed from having one of the world's highest gambling facility densities to implementing strict regulations. Using a sample of 2,447 respondents from 277 municipalities, the research analyses how daily encounters with gambling facilities, rather than mere facility presence, influence gambling behaviour. The study incorporates individuals' accessibility based on daily encounters within their living space, moving beyond conventional metrics of availability. Results show that the extent of encounters during daily routines is a stronger predictor of gambling participation than facility presence alone, with the most pronounced effects observed in casinos and gaming halls. Municipalities with comprehensive gambling offerings showed the highest proportion of at-risk and problem gamblers. These findings emphasise the importance of considering population mobility in gambling accessibility analyses and suggest implications for local regulatory policies.
