What the numbers mean in Mountainside borough

Housing cost measured against local earnings.

A household earning the Mountainside borough median would spend about 20% of gross income on the median rent. The 30% mark is the federal threshold for cost burden, so anything above it signals a stretched rental market. The median home costs 3.6× the median household income; nationally that ratio sits near 4.5×. Poverty affects 2.8% of residents and 86.9% of households own their home.
