Sources & method

Where every number comes from

Method

  • People: U.S. Census Bureau American Community Survey 2020–2024 5-year estimates, plus the 2010 and 2020 Census counts, read from census.gov QuickFacts, Census Reporter and Data USA (which republish the same Census tables). Small places carry wide margins of error. Figures not available from those sources are left blank rather than estimated.
  • Race and ethnicity: the Census counts Hispanic origin separately from race, so the "100 neighbors" grids use only groups that do not overlap: White not Hispanic, Hispanic or Latino of any race, and everyone else.
  • Schools: NJ Department of Education School Performance Reports (2023–24) and district budget summaries; private and child-care listings from directories that republish NJ Department of Children and Families licensing data. Entries whose in-town location could not be confirmed are marked.
  • Trains: station records from NJ TRANSIT, the NJ Historic Preservation Office and station histories. Travel times are not shown because the timetable was in transition during research (Portal North Bridge cutover).
  • Development: projects reported with a date by local and trade press, municipal planning documents and NJDOT. Status is as of the source date shown on each project.
  • Stories: municipal, state, National Park Service, Army and historical-society sources, plus encyclopedia entries; every fact links to the page it came from.
