Communities · 2020–2024 ACS estimate

ACS figures describe a five-year collection period. Their published margins of error are shown. Adjacent estimates may not differ significantly.

This comparison applies the directory's selection policy to those estimates. Historical or unresolved identities remain available in native lookup, outside the comparison, even when an older population estimate is available. A town and an overlapping Census-designated place can both appear as typed geographies.

These are overlapping jurisdictions and communities. Do not add their populations together. A directory count describes this selection policy.

364 entries in this view. The initial list shows up to 50 entries per section.
