Maryland is one of the happiest places on earth.  Well, maybe not, but Wallet-Hub says it's in the top two of happiest states in our Republic. Here's what the authors of the study say they figured it out:

"In order to determine the happiest states in America, WalletHub compared the 50 states across three key dimensions: 1) Emotional & Physical Well-Being, 2) Work Environment and 3) Community & Environment.

We evaluated those dimensions using 30 relevant metrics, which are listed below with their corresponding weights. Each metric was graded on a 100-point scale, with a score of 100 representing maximum happiness.

Finally, we determined each state’s weighted average across all metrics to calculate its overall score and used the resulting scores to rank-order our sample."
