Households in St. Bonaventure are small: just 1.67 people on average, compared with 2.65 nationally. That is typical of places where many people live alone or as couples, and fewer have children at home. Since 2006–10, household size has dropped from 2.00, but in a place this small, much of that may be survey noise rather than real change.

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 St. Bonaventure. 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.
