Massachusetts-relative analysis
Among the 247 Massachusetts cities PlainCities tracks with reported bachelor's degree or higher data, South Duxbury ranks #10 - the 96th percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares South Duxbury only against its own state's cities, not the full US field.
Ranked by raw value (highest first); a higher rank is not automatically "better" for every measure, see each metric's own context above. This is a comparison within Massachusetts only, not a livability score. See the methodology for the source and calculation.
