How to read this county's bill

The bill here climbed steeply over 2020-2024, up 25% from $1,275 to $1,595. These ACS medians describe the reported change; they do not identify whether a levy, assessment, home value, or change in the responding households caused it.

The fullest band here is the $800 to $1,499 range, holding 1,194 of 3,799 owner-occupied homes (31.4%). The band shows where the largest share of reported owner-occupied households falls; it is not an individual-bill estimate.

Incomes run above the national midpoint and the rate is in the lowest quarter, leaving the median bill at 2.4% of median household income. Both figures move in the same direction here, so the ratio above is not pulled in two directions the way it is in most counties.

The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
