Households in Index are small: just 2.30 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.

Index skews older: half of its residents are older than 52.9, well above the national median of 40.1. That usually means more empty nesters and retirees, and fewer young families. The median age has climbed from 42.6 in 2006–10, but in a place this small, much of that may be survey noise rather than real change.

Index is overwhelmingly a place of homeowners: only 13.7% of households rent, far below the national share of 34.8%. Owner-heavy areas like this tend to see less turnover. Nearly half of owners (47.0%) have paid off their mortgages, above the national share of 39.8%.

Vacancy is high in Index: 50.8% of homes are empty, far above the national rate of 9.6%. In resort and lake areas that usually means seasonal and vacation homes; elsewhere it can point to weak demand.

A typical rental in Index costs $1,477 a month with utilities, below the national median of $1,571. The typical renter here spends 39.8% of household income on rent, well over the 30% mark often used to define affordable rent, so many renters here are stretched.

Unemployment in Index runs well above the national rate: 15.6% of the labor force was out of work and looking, against 5.4%. 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 Index. 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.
