The ratio of home value to household income is a measure of housing affordability and the financial sustainability of home ownership. It is calculated by dividing the median owner-reported home value by the median annual before tax household income of homeowners. A higher ratio indicates a greater affordability challenge, typically reflecting high property values relative to household earnings. This metric helps identify areas where housing costs may be disproportionately high compared to residents' incomes, and highlights affordability differences across housing types and jurisdictions.
