I appreciate the results from research that WalletHub posts especially this one about "2021's Happiest Cities in America." It's very interesting that money does not play a big role.
While I love several cities in Michigan, Charleston, SC is my happiest city because of weather, views, plus simply having many places to go and simply be active. People are very happy there and in great shape. I once lived in Chucktown and often visit.
No surprise that Grand Rapids scored high. Check out the huge list of cities and what ranked them at WalletHub.
