Studies and surveys can't be instantly generated and it is hard to find the latest especially during the pandemic.
Anyway, I've got this
Top 10 Gambling Cities in the World in 2020 and has been published earlier this year, maybe this could help us. But probably there is a huge change when the pandemic hits us badly. However, I don't expect a huge change then.
Well, it is to expect that many countries have a massive growth of gambling institutions. And as OP mentioned about losses, it probably more than that as we think.
the links on the first post are from 2015 and 2017 but yours are from 2020 the more recent the more accurate i guess ? thanks for the links and by the way i gather the countries that are top 10 active in gambling from your link and here are they :
10.) Los Angeles, California
9.) Paradise Island & Nassau, Bahamas
8.) London, United Kingdom
7.) San Jose, Costa Rica
6.) Paris, France
5.) Atlantic City, New Jersey, USA
4.) Marina Bay, Singapore
3.) Monte Carlo, Monaco
2.) Las Vegas, Nevada, USA
1.) Macau, China
the huge change is that online gambling are now popular . gambling business are affected at the start of covid but later on they open doors online and its now back and bigger than ever but other countries that have recovered from covid are now going back operating offline . losses of people from those countries might be big but what about the wins , arent we going to talk about them
