Final answer:
The exact percentage of Americans who feel they are managing their stress excellently or very well is not provided in the excerpts. Surveys indicate various stress levels across different demographics, influenced by personal and economic factors. For precise statistics, one should consult the latest research data or surveys.
Step-by-step explanation:
The question at hand is inquiring about a specific statistic related to Americans' self-assessment of their stress management capabilities. Unfortunately, the provided excerpts do not directly answer the question concerning what percentage of Americans feel they are doing an excellent or very good job of managing their stress. To find precise and current statistics, one would typically refer to recent surveys or studies conducted by psychometric researchers or institutions specializing in psychological health.
One reference provided does mention the impact of economic conditions on stress, indicating higher stress in women than in men, with certain demographics feeling the effects more acutely. Significant stressors included economic downturns and the corresponding consequences, such as job loss or reductions in retirement savings. It is important to consider that an individual's stress management assessment might fluctuate based on personal circumstances and larger societal factors.
It should also be noted that results of surveys might vary significantly depending on the time of the survey, the sample size, and the socio-economic context in which they were conducted.
