The California marriages of scientists, actuaries, physicians and software developers may be less vulnerable to divorce than those of flight attendants, bartenders and casino workers. A study found that people who work in the fields of math and science have lower-than-average divorce rates while the rates of those who work in transportation or whose work involves night life are higher than average. Professions that are more popular in rural areas, including military careers, forestry, fishing and farming, also had a lower-than-average divorce rate.
