Only 11.0% of households in South Randolph rent their homes, far below the national share of 34.8%, so most residents are owners who tend to stay put. About half of owners (49.8%) have paid off their mortgages, above the national share of 39.8%. Since 2006–10, the renter share has fallen 1.8 points, but in a place this small, much of that may be survey noise rather than real change.

The job market in South Randolph has been strong: just 2.0% of the labor force was out of work and looking, well below the national rate of 5.4%. The picture is much the same across the Madison area. Because the Census pools five years of responses (2020–24), these rates smooth over short swings and lag the current job market.

Unemployment: people looking for work as a share of everyone working or looking. Source: BestNeighborhood calculations from U.S. Census Bureau ACS 5-year block-group estimates (table B23025).

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 South Randolph. 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.
