Numerous surveys and studies confirm that occupational pressures and fears are far and away the leading source of stress for American adults and that these have steadily increased over the past few decades. While there are tons of statistics to support these allegations, how significant they are depends on such things as how the information was obtained (self-report vs. answers to carefully worded questions), the size and demographics of the targeted group, how participants were selected and who sponsored the study. Some self-serving polls claiming that a particular occupation is "the most stressful" are conducted by unions or organizations in a attempt to get higher wages or better benefits for their members. Others may be conducted to promote a product, such as the "Stress In the Nineties" survey by the maker of a deodorant that found housewives were under more stress than the CEO's of major corporations. Such a conclusion might be anticipated from telephone calls to residential phones conducted in the afternoon. It is crucial to keep all these caveats in mind when evaluating job stress statistics.
