COMMON QUESTIONS

Maine county map questions.

Which county contains Portland, Maine?

Portland is in Cumberland County. Use 23005 for a county-level join.

Which county should I use for Bangor?

Bangor is within Penobscot County, which has GEOID 23019.

Can I select Down East as one region?

The editor selects individual counties. To show a regional group, give the relevant counties a shared color and explain your definition in the legend.

Why does Washington County appear with an eastern coastline?

This is Washington County, Maine, at the eastern edge of the state. The GEOID 23029 identifies it independently of other Washington counties.

Do the colors cover every Maine island?

The Census cartographic file generalizes shorelines and omits some small features. Islands represented in the editor share the fill of their county.

How do I tell population change from domestic migration?

Population change compares the total from two dates. Domestic migration measures net moves within the United States. Check the map’s units and dates before sharing it.
