This month's Kaiser Health Tracking Poll examined views on health insurance among young adults, the uninsured and those with pre-existing conditions.
Among the public overall, 87 percent said it was very important to them personally to have health insurance, 88 percent described health insurance as something needed and two-thirds said insurance was worth the money.
Even among younger adults -- a group many speculated might be resistant to getting coverage under the Affordable Care Act -- more than 7-in-10 said it was very important to them personally to have health insurance, but 4-in-10 said cost was the biggest barrier for the uninsured.
Just a quarter of those ages 18-30 said they were healthy enough to go without insurance.
Roughly half of those age 65 and younger said they or a household member has a pre-existing condition, and a quarter of them said they had either been denied insurance or had their premium increased as a result.
Among those age 30 and younger, roughly two-thirds said they were worried about "not being able to pay medical bills in the event of a serious illness or accident," while more than 4-in-10 said they worried about affording medical bills just for routine healthcare services.
The survey was conducted June 4-9 among a nationally representative sample of 1,505 U.S. adults. The margin of error was 3 percentage points.
