Massachusetts municipalities face a recurring pattern: the right question is obvious, the authoritative data exists across offices, and no one person has time to run the cross-cut. Parcenomics builds the analytical layer that does. Every engagement starts with the same data foundation — your assessor’s CAMA database, voter roll, commitment records — and reuses it across whatever set of questions your community faces most urgently.
Every engagement begins with a day walking the town and a data access agreement — then your assessor’s database, your clerk’s voter file, your recap. Built once, used across all five. The agreement is what makes the work sustainable rather than what makes it possible: the two analyses on this site were built from public records alone, with nothing signed by anybody. Start with whichever question your Select Board, Finance Committee or Council is facing this quarter — the urgent question decides what leads, not what you get. It is one engagement on one foundation, and there is nothing here to buy in pieces.
Each one arrives twice: as a report that traces every figure to the public record, and as a dashboard your board can run in the room. Open Great Barrington’s →
Massachusetts gives a town a dizzying number of choices here, and none of them stands alone. The split rate across all five property classes. The open-space and small-commercial discounts. The personal exemptions. And, within the residential class itself, the residential exemption. This models every permissible configuration and shows what each does to the residential burden, to commercial taxpayers, and to total revenue — including who gains and who pays more at every setting. Your Select Board or Council votes on the arithmetic instead of last year’s number.
Explore Classification & ExemptionsIdentifies property owners who may be underpaying — or not paying — personal property and applicable excise obligations. Produces named, ready-to-act deliverables: demand packages, evidence files, and enforcement toolkits your assessor can use immediately.
Explore Compliance ReviewCompares sale prices against assessed values to calculate how the tax burden is actually distributed across property value tiers and neighborhoods. Identifies systematic patterns — modest homes carrying more than their share, high-value properties less — before they compound into abatement waves or DOR compliance problems.
Explore Equity AnalysisAnalyzes your registered voter file and annual street listing to produce a demographic portrait of the people who actually vote in your community — age distribution, party mix, household density, and registration tenure — benchmarked against Massachusetts and U.S. adult population baselines. The lightest-weight municipal engagement, and often the right place to start. Grounds every subsequent policy question in the actual community it will affect.
Explore Voter Profile View Sample →Reconstructs fifteen-plus years of your town’s fiscal history from MA Department of Revenue Tax Rate Recapitulations, LA-13 new-growth certifications, and Equalized Valuation data. Quantifies what portion of recent tax-base growth came from new construction versus renovation-and-rebuild of existing properties, tracks tax-rate and levy trajectory in both nominal and inflation-adjusted terms, and places your municipality in peer context. Closes by naming the specific policy decisions under Massachusetts General Laws — rate structure, the Residential Tax Exemption, local option revenue mechanisms — that the data informs, without recommending how any of them should be resolved.
View Sample →Not a sixth analysis — the way the other five arrive. Every finding above becomes a control your board can move in the room: the configurations on a slider, the recovery streams from conservative to aggressive, what re-anchoring a tier does to every bill in town. Nothing on it moves alone, so what you are looking at is always the combined effect rather than one lever pretending the rest of the town is holding still. Every control carries an explanation, a line naming who would have to vote for it, and a label for how solid the figure is. Set it to the certified year and it reproduces your Tax Rate Recapitulation exactly.
How the dashboard worksYour municipality has the data. It just exists in different silos — the Assessor’s CAMA system, the Treasurer’s commitment records, the Clerk’s voter roll and street listing, the regulatory framework of MGL. Parcenomics synthesizes these data sets, verifies them against state statutes and formulas, and produces analytical options for your leaders to consider.
The analytical infrastructure I build for your first engagement — the data access agreements, the CAMA ingestion pipeline, the classifier calibrated to your municipality’s data idiosyncrasies — is durable. A second question builds on the first. A third builds on both. Marginal analytical cost falls as the data foundation deepens. Communities that start with one product often add the others over time, not because I push them, but because the infrastructure is already there.
