What this figure is
It is not a sale price. The Census Bureau asks homeowners what they think their home would sell for, and this is the middle answer for owner-occupied homes in New Castle County. It covers every kind of home people own and live in, so the price of a particular house on the market can be far from it.
The figure describes the whole of 2020–2024, not a single year, and it is not adjusted for price changes since then. The smaller a county, the fewer households the survey reaches and the less exact its estimate: here the true value is very likely within $3,776 of the one shown.
