Households in Grantsburg run a little small, averaging 2.55 people against 2.65 nationally, which usually means more singles and couples and fewer children. Even so, the typical household here is bigger than in Wisconsin overall, where it has 2.40 people. Since 2006–10, household size has climbed from 2.23, but in a place this small, much of that may be survey noise rather than real change.

Because the Census pools five years of responses (2020–24), these rates smooth over short swings and lag the current job market.

About these numbers

Every figure on this page is a BestNeighborhood calculation from the Census Bureau's American Community Survey (ACS), built up from the Census block groups that make up Grantsburg. Each ACS 5-year release pools five years of responses; this page shows the last 15 releases, 2006–10 through 2020–24. Neighboring releases share four of their five years, so they move gradually and small changes between them are within the survey's margin of error; in small places the lines can jump from one release to the next for the same reason. The maps show the same measures for each neighborhood, ranked against the whole country.
