COMMON QUESTIONS

New Hampshire county map questions.

Which county should I use for Manchester or Nashua?

Both cities are in Hillsborough County. A county join assigns a single fill across Hillsborough.

Can a New Hampshire county map show individual town data?

The editable units are counties. Aggregate compatible town observations to counties before importing, or use a town-boundary map for town-level comparisons.

How do I find the northernmost county in a CSV?

Use Coos County’s Census GEOID, 33007. The directory follows the Census spelling used in the pinned data.

How can Coos have positive domestic migration and a declining population?

Domestic migration is one component of population change. Births, deaths, international migration and statistical adjustments also affect the total.

Which county contains the New Hampshire seacoast?

Rockingham County contains the state’s Atlantic shoreline. Strafford sits just to its north.

Which columns work for a county CSV?

Use the five-digit GEOID as the match column and put your measurements in a separate column. A short formatted CSV with county names is provided on this page.
