Which states are actually the Mid-Atlantic
There is no single answer, and the disagreement matters more than it sounds — federal data tables, carrier rating territories and regulatory compacts all draw the line differently.
This index covers seven of those markets — New Jersey, Pennsylvania, Delaware, Maryland, Washington D.C., Virginia and West Virginia. It uses the wider commercial definition rather than the federal statistical one, for a practical reason: insurance is regulated state by state, and the states the Census leaves out are the ones where the region's sharpest divergences show up. Where a figure comes from a federal table built on the three-state definition, that is noted.
What happened to everyone in 2026
One event dominates every state summary below. The enhanced premium tax credits established in 2021 expired at the end of 2025 and were not renewed, and 2026 rate filings were built on the assumption that healthier enrollees would drop coverage as a result.
Nationally, ACA marketplace premiums rose about 26% for 2026 — roughly 30% in states using the federal HealthCare.gov platform against about 17% in states running their own marketplaces. Analysts attribute the gap to three policy choices: whether a state runs its own marketplace, whether it operates a reinsurance program, and whether it expanded Medicaid. All eight jurisdictions here expanded Medicaid, and all but one run a state-based marketplace — which is why the Mid-Atlantic came through 2026 better than the national average, though not evenly.
Property insurance moved on a separate track and for different reasons. Even Mid-Atlantic states that no buyer would call catastrophe-exposed have seen cumulative premium growth of roughly 25% to 29% since 2021, driven largely by reinsurance costs that price globally rather than locally, plus rebuild-cost inflation.

Home premiums are market-level averages for a roughly $300,000 dwelling policy and vary widely by carrier, ZIP code and construction. Age figures are approximate shares of total population. Full sourcing at the end of this page.
Where each one actually stands
New Jersey
NJ · Tier 1New Jersey's distinguishing feature is that it did not wait for Congress. The state's own subsidy program extends well up the income scale, which cushioned the 2026 shock for a broad band of middle-income households that in other states absorbed it directly.
On property, the state's numbers look better than its geography suggests. Shore exposure is real and priced accordingly at the ZIP-code level, but the statewide average remains comparatively modest — the pressure is coming from reinsurance and rebuild costs rather than from claims history.
Pennsylvania
PA · Tier 1Pennsylvania runs its own marketplace and expanded Medicaid, and still absorbed one of the harder 2026 increases in the region. The reason is the risk pool: an old state with a large rural population and a substantial share of self-employed, gig and small-business enrollees who buy individually and have no employer to absorb the shock.
The property story deserves separate attention. A 44% cumulative rise since 2021 in a state with no hurricane exposure, no wildfire exposure and modest catastrophe history is the clearest available evidence that reinsurance pricing has decoupled from local risk.
Delaware
DE · Tier 2Delaware is the case study the rest of the region should be reading. It has the demographic profile of Maine or Vermont — an aging-in-place population plus heavy retiree in-migration — attached to a healthcare delivery system sized for a much smaller and much younger state. Cheap insurance and scarce care are not a contradiction here; they are the same story seen from two ends.
Sussex County is where this concentrates. The entire county is federally designated a Medically Underserved Area and a Health Professional Shortage Area, while the Lewes–Rehoboth coastal corridor absorbs some of the fastest residential growth in the state. Two companion briefs examine that collision in detail.
Maryland
MD · Tier 2Maryland is the region's best argument that state policy choices change outcomes. Its reinsurance program absorbs high-cost claims before they reach the general risk pool, and the result is a market with both low premiums and — until this year — stable carrier participation.
The 2026 caveat is on the back end rather than the front. State officials have signaled an expectation that high premium payments will push more enrollees to cancel coverage outright or lose it for non-payment as the year progresses. A low sticker price does not help someone who has already dropped the policy.
Washington, D.C.
DC · Tier 2The District is included here mostly as a control. It shares the region's regulatory environment and its carriers, but almost none of its demographic pressure — a young, transient, heavily employer-insured population with abundant nearby specialty care.
Its relevance to the rest of the Mid-Atlantic is comparative: when a regional average is quoted, D.C. is often pulling it in a direction that describes no other jurisdiction here.
Virginia
VA · Tier 3Virginia presents the sharpest split of any state in this index. On health coverage it is among the best-positioned jurisdictions in the country: low benchmark premiums, a modest 2026 increase, and a young-enough risk pool to sustain both.
On property it took one of the worst single-year hits in America. A 37% jump in a state without Gulf hurricane exposure or Western wildfire exposure points at severe convective storm losses, rebuild-cost inflation and reinsurance repricing rather than at any one catastrophe.
West Virginia
WV · Tier 3West Virginia is the region's counter-example to Delaware, and the comparison is instructive. Both are old states. Delaware is old because retirees keep arriving; West Virginia is old because younger residents left and birth rates fell. Same headline share, opposite mechanics — and opposite policy implications.
The market consequence is a small, rural, high-morbidity risk pool with few competing carriers, on the federal platform, without the reinsurance or state-subsidy tools its neighbors used to blunt 2026. It is the clearest illustration in this index of what those tools are worth.
What they have in common, and what they don't
Three findings hold across the region.
State tools worked. Reinsurance programs, state-based marketplaces and state subsidy backfills produced measurably lower 2026 increases. Maryland and New Jersey each used a different instrument and each landed better than the national average. West Virginia, without any of them, did not.
Property pricing has decoupled from local risk. Pennsylvania is up roughly 44% cumulatively since 2021 and Virginia 37% in a single year, in states with no hurricane or wildfire exposure. Reinsurance is priced globally, and the Mid-Atlantic is now paying into losses that occur elsewhere.
The aging split runs through the middle of the region. Delaware, Pennsylvania and West Virginia have among the oldest populations in the country; D.C. and Virginia among the younger. Any policy pitched at "the Mid-Atlantic" will fit roughly half of it.

METHOD AND DISCLOSURE — This index compiles publicly available figures from federal and state sources, regulatory filings, and published reporting, current as of August 2026. Premium figures are market-level averages and projections from third-party analysts; they are not quotes and will differ substantially by carrier, ZIP code, age, construction and coverage level. Percentage changes for health coverage refer to benchmark or average approved rates before subsidies, which is not what most enrollees actually pay. All 2026 ACA figures are provisional: the 2026 plan year is the first following the expiration of the enhanced premium tax credits, and enrollment, cancellation, non-payment and effectuated-enrollment data continue to be revised. These figures describe the shape of the market rather than settled totals and should be re-verified against current KFF and state regulator data before use. Age and population shares are approximate. Long-term care legislation described here is proposed rather than enacted except where noted. Research, drafting and formatting were assisted by AI tools, with sourcing verified and all analysis, framing and conclusions the author's own. Nothing here is insurance, legal, medical or financial advice.
