This report presents the results of the first patron survey at Encore Boston Harbor (EBH), completed in 2022. Findings include insights on demographics of casino visitors, behavior, and expenditures. Spending of MA residents that has been recaptured from out of state appears to constitute a major share of EBH’s revenues, though not all represents new economic activity. An important social issue concerns whether people with lower incomes contribute disproportionately more to gambling revenues than people with higher incomes; this does not appear to be the case at EBH.
