Higher-income adults are less worried about the economy and unemployment, but slightly more concerned about health care.

Those were some of the results of an online survey by Ipsos Mendelsohn, which was completed by about 1,000 adults from households with annual incomes of $100,000 or more.

In the survey, completed in September, 43% of respondents said they were concerned about the economy, which is down from 60% in July.

Concerns about unemployment and jobs were cited by 34%, down from 37%.

Thirty-eight percent said they were concerned about health care, which was up from 36%.

Overall, those expressing optimism about the U.S. economy rose from 49% to 54%.
