Halfmoon skews older: half of its residents are older than 53.9, well above the national median of 40.1. That usually means more empty nesters and retirees, and fewer young families. Since 2006–10, the median age has climbed from 45.9, but in a place this small, much of that may be survey noise rather than real change.

Jobs have been easier to find in Halfmoon than nationally: unemployment was 3.5%, against 5.4%. The picture is much the same across Montana. 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 Halfmoon. 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.
