New Hampshire's
unbuilt list.

A 23,897-home deficit for its poorest renters, a third of its state-owned high-hazard dams in poor condition, $6.8 billion of documented water need — and two national hospital screens that flatly disagree about whether its rural hospitals are safe.

How to read this page: the class chip on every measure is the honesty label. Counted = an inspection or enumeration record. Modeled = a study's projection or risk score — printed with the modeler's name. Assessed = a structured survey of required investment — needs as documented, not measurements of decay. Figures keep the form their source gave them; years are printed on every measure.

Coverage note — New Hampshire

Every measure carries its value, class, geography, year, definition, context and source. Three New Hampshire-specific cautions are printed rather than smoothed over. Hospitals: the two national screens disagree outright — CHQPR finds 4 of 13 rural hospitals at risk while the Chartis model puts the state at 0% vulnerable — so both are printed, labelled by instrument, and the severity score sits between them with the reason stated. Traffic: New Hampshire has no large metro, two of its three TTI areas are bi-state and are labelled as such, and Boston's metro figures are deliberately NOT used as a New Hampshire measure. Power: every figure is an ISO New England regional figure and says so.

Instruments are never blended: USDA's surveyed household rate (9.1%) and Feeding America's modelled individual count (≈150,000) sit side by side unmerged; the broadband dashboard's addresses (≈10,000) are not mixed with BEAD location counts (9,527 designated in January 2025; ≈5,250 after the June 2025 federal restructuring), whose history is stated in the defnote instead; and the dam figures are the state owner's own (NHDES testimony), printed over weaker national-inventory scrapes. News-flagged: several measures are sourced to news reporting of official data and are flagged on their records — the CHQPR hospital screen and the labour-and-delivery closure count, the NHDES dam figures, and the BEA broadband dashboard count.

Severity scores are editorial (0–100 band), calibrated against the other states in this series — New Hampshire's range (42–80) reflects a state whose worst-case housing squeeze and state-owned dam backlog are genuinely severe, and whose traffic and broadband pictures are among the mildest in the series.
