📝 How we sourced this

Population, income, and housing-cost figures come from the U.S. Census Bureau American Community Survey 5-year estimates (B-series tables). Crime data uses FBI UCR; climate uses NOAA Climate Normals; school counts come from NCES Common Core of Data; permits use the Census Building Permits Survey (BPS). See our methodology page for the full ETL pipeline and OMB / FIPS join keys.

A decision-led reading path

Useful questions to ask of South Duxbury's data

How this reading path is ordered

This is not a composite city score. It is a city-specific route through the available public records, ordered for this profile so the page starts with questions the joined data can actually answer. The route here runs from comparison shortlist to housing and income to work and mobility; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

For South Duxbury, city-specific coverage includes commute-mode shares. No matched row is reported here for within-city Census tract profiles, FBI reported-crime rates, matched public-school count, local building permits, annual population history; the page leaves those layers out instead of substituting a statewide or national value.

Question 1

Which cities make useful reference points for South Duxbury?

Within Massachusetts, the closest population matches are Nahant (3,328 residents, $111,004 income); South Dennis (3,190 residents, $86,500 income); Hopkinton (3,142 residents, $173,750 income). Outside the state, the closest population matches in this dataset are Lake Arrowhead, ME (3,273 residents); Paoli, IN (3,274 residents); Minerva, OH (3,274 residents). A third, income-matched reference set of 6 out-of-state cities sits in the income neighbourhood chart near the Place Dossier plate. These are mechanical peer sets, not claims that the places share a labor market, climate, culture, or metro context.

Use the in-state set to hold state policy and broad price conditions more nearly constant. Use the nationwide size set to ask whether cities with a similar resident count produce different housing, income, or commute outcomes. The income set is a third lens, deliberately separate from population matching.

Open a side-by-side comparison →

Question 2

How far does income reach against housing in South Duxbury?

The home-value-to-income reference is comparatively stretched: the ACS median home value is 4.8 times median household income. The ACS poverty estimate is 3.8%, which keeps the citywide median from describing every household.

This is a citywide price-to-income reference, not a mortgage-affordability test; it does not include interest rates, taxes, insurance, household size, or an individual buyer's down payment. Housing value is high relative to the citywide income median. That flags a question for comparison, not a verdict: tenure, household composition, financing costs, and the age of the ACS estimate can all change what a resident actually pays.

Compare the housing trade-off →

3. Work and mobility

What does the journey to work look like in South Duxbury?

Mode share answers how workers usually travel; it does not measure congestion, reliability, distance to a particular job, or the quality of transit service. Remote work has a visible role in the local pattern. That can reduce commute exposure for some workers, but it says nothing about job availability or broadband quality; read it alongside income and housing rather than as a stand-alone lifestyle score.

Driving alone is the largest reported mode at 55.8%. A reliable mean commute time is not available for this row, so the mode shares carry the comparison.
