Orange County is home to two of the nation’s happiest and low-stress cities, according to a pair of rankings.

In the past year, the financial information website WalletHub has twice ranked 182 big U.S. cities – including 29 in California – for measures of what I’ll call “serenity.”

One measure tracks happiness while the other gauges stressful living. Happy was defined by 29 metrics to score well-being, economics and community, while 39 data points graded key stresses — work, financial, family, health and safety.

My trusty spreadsheet averaged those grades to rank the cities for an overall sense of serenity. Irvine ranked No. 7 in the combined scorecard, with a No. 3 grade for happiness and a No. 16 score for low stress. Huntington Beach was No. 18 for serenity — No. 10 for happiest, and No. 34 for least stressed.

The most serene city was the Bay Area’s Fremont, which received the top honor in both rankings. Others in the serenity top five were Sioux Falls, South Dakota; Lincoln, Nebraska; Overland Park, Kansas; and Bismarck, North Dakota.

The Bay Area also had high on the serenity scorecard: No. 6 San Jose — from a No. 2 happiest grade and a No. 15 least-stressed ranking — and No. 24 San Francisco — No. 9 happiest and No. 43 least stressed.
