The average household in Treaty has 2.42 people, under the U.S. average of 2.65. Since 2006–10, household size has climbed from 2.31, but in a place this small, much of that may be survey noise rather than real change.

Treaty skews older: half of its residents are older than 46.9, well above the national median of 40.1. That usually means more empty nesters and retirees, and fewer young families.

Unemployment in Treaty has been low: just 2.9% of the labor force was out of work and looking, well below the national rate of 5.4%. 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 Treaty. 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.
