Sources and limits
- Permits come from the town’s list of overnight on-street parking permits granted, as of September 8, 2026. I match each address to its tax parcel, place the parcel in a precinct and keep only the count to anonymize permit holders.
- Precinct lines and residents come from MassGIS Wards and Precincts 2022, with 2020 census population.
- Main streets come from MassDOT’s Road Inventory. They’re there to help you find your way and aren’t tied to any permit.
