A 160,543-home deficit for its poorest renters, 190.7 million hours of Boston-metro delay, about $37 billion of documented water need and 333 high-hazard mill dams — in a state whose rural hospitals, unusually, screen at zero risk.
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.
Click any category to expand it — every measure with its figure, what it means in plain language, and its source.
Every measure carries its value, class, geography, year, definition, context and source. Three Massachusetts cautions are printed rather than smoothed over. Traffic: TTI's Boston per-commuter row could not be verified from Table 7 in the sources reviewed, so the category prints Boston's verified metro TOTAL (190.7M hours, Table 3) and a verified per-commuter figure for Barnstable Town instead — no Boston per-commuter number is invented. Hospitals: the category rests on one published screen (Chartis, via Becker's: Massachusetts at 0% vulnerable) because that is what the instruments publish for a state with a very small rural fleet; no CHQPR Massachusetts count was verified and none is printed. Power: both measures are ISO New England REGIONAL figures and are labelled regional on their faces — Massachusetts has no separate grid.
Instruments are never blended: USDA's surveyed household rate (11.7%) and Feeding America's modelled individual rate (11.5%) sit side by side unmerged, and the Greater Boston Food Bank's broader lived-experience survey (about one in three households) is named in the food defnote rather than averaged in; TTI's metro-total and per-commuter instruments are labelled as different measures; ASCE's drinking-water estimate (a 20-year, 'more than $15B' figure, tallied at its floor) is not presented as the same kind of number as the EPA's $21.7B wastewater need. News-flagged: the hospitals screen (Becker's summary of Chartis) and both water figures (trade-press restatement of the ASCE 2026 report card) are flagged on their records.
Severity scores are editorial (0–100 band), calibrated against the other states in this series — Massachusetts' range (48–92) reflects a wealthy state with a worst-tier housing deficit and congestion, a D-graded water estate, and a genuinely strong rural-hospital screen.
