With a median age of 46.0, Petersburg is noticeably older than the country as a whole (40.1), an age mix that tilts toward empty nesters and retirees. The median age has climbed from 41.5 in 2006–10, but in a place this small, much of that may be survey noise rather than real change.

Unemployment in Petersburg runs below the national rate: 4.2% of the labor force was out of work and looking, against 5.4% nationally. The picture is much the same across Indiana. 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 Petersburg. 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.
