America’s casino gamblers will skew a lot younger once the industry reopens following the COVID-19 shutdown, at least initially, according to a new survey.

A new survey by gaming developers Synergy Blue asked 1,000 consumers – “specifically those who gamble” – how their approach to casino gambling has been altered by the COVID-19 pandemic. The survey found that 51% of gamblers would return to casinos once the venues are allowed to reopen.

Of those who remain skittish about crossing a casino threshold, 58% cited economic concerns, while 47% expressed concern over how sanitary the environment will be and 41% simply didn’t feel good about being in a confined space with lots of other people.

Around one-quarter of respondents are waiting for the number of COVID-19 infections to fall dramatically before they’ll return to casinos, while 19% say they won’t return until there’s a vaccine that can eliminate the threat entirely.
