Each bar is one fiscal year. Dark = passed, light = did not pass.
Percentage of override ballot questions that passed in each fiscal year.
Many towns split one override into multiple ballot questions (Chatham FY1990 had 31). The per-election line combines all questions from one town in one year; the per-question line shows each ballot item individually. The two converge in recent years as towns shift toward bundled questions.
Override vote data from the Massachusetts Department of Revenue, Division of Local Services Municipal Databank, Proposition 2½ Override/Underride Database. Dataset includes 4,640 operating override ballot questions (underrides excluded) across 305 municipalities from FY1990 to FY2027.
Each ballot question counts as one vote, regardless of dollar size. A single town election can have multiple ballot questions (e.g. Needham FY1997 had ten separate override questions).
FY2027 data is partial as of April 2026. One Marblehead row (FY2025, "Fix Clerk Error", $0) is excluded as a clerical correction.
"Pass rate" is the number of questions that passed divided by total questions in that fiscal year. It does not weight by dollar amount or population.
"Per ballot question" median is the median of all individual ballot question amounts in a given fiscal year. "Per election" median aggregates all questions from the same town in the same fiscal year into a single combined amount before computing the median. The gap between the two lines reflects how many towns split overrides into multiple line-item questions rather than one bundled vote. In nominal (not inflation-adjusted) dollars.
