Half the uninsured here sit in the subsidy range

Coverage is worse here than across the state

13.5% of Union County's 493,504 under-65 residents have no health coverage — 66,715 people. That is well above New Jersey as a whole at 9.0% — 4.5 points above its own state, and puts Union County in the top quarter of the 3,143 counties measured nationally (686th).

Who falls under the Medicaid line

18,371 of Union County's uninsured — 28%, close to the 31% typical nationally — earn under $22,025 a year, which in New Jersey is Medicaid territory rather than marketplace territory.

Older residents here are better covered

12,060 people aged 50 to 64 in Union County have no coverage, a rate of 10.7% — lower than the 13.5% across all under-65 residents here, which is the usual pattern — people in their fifties and early sixties tend to be more settled in employer coverage. Age-rated premiums make this the most expensive group to cover before Medicare.
