A new study of Atlantic City casino visitors shows that millennials spend two-thirds less money on gambling than older visitors.

New research by the Lloyd D. Levenson Institute of Gaming at Stockton University shows that millennials – defined as people between 21 and 35 years of age – spend just 8.5% of their total AC trip budget on gambling, versus 23.5% by visitors over 35.

The study involved over 500 individuals from 22 states, with around 350 of those surveyed meeting the millennial definition. Of the total number surveyed, 352 had visited AC in the past 12 months.

Around 21% of millennials said gambling was an important part of their visit, half the figure cited by the over-35s. On a chart of 28 activities, millennials ranked gambling 21st in importance while non-millennials ranked gambling in seventh place.
