Vacant ratio.
The share of all housing units in a geography that the Census classifies as vacant. Published as part of ACS housing statistics.
What's included
The Census definition of “vacant” includes more than just rental units sitting empty:
- For-rent vacant — the closest analog to operational rental vacancy
- For-sale vacant — listed but not yet sold
- Seasonal, recreational, or occasional use — vacation homes
- For migrant workers — typically rural and agricultural
- Other vacant — held off market, awaiting probate, undergoing renovation
The mix of these categories shifts the meaning of the number. A coastal resort market with 30% vacant ratio is mostly seasonal homes; a Rust Belt market with 30% vacant ratio is mostly demand-side weakness.
How to read it
In non-resort markets, persistently high vacant ratios often point to population decline, chronic oversupply, or units held out of productive use. Those conditions can translate into structural rent and price pressure.
