Housing Stock by Tenure

Housing Stock by Tenure Methodology

This methodology classifies a community's housing stock into three tenure categories — owner-occupied, renter-occupied, and vacant — across two physical dimensions: structure type and bedroom count.

Tenure Categories

Each housing unit is assigned to one of three tenure categories:

Vacant units are not reported directly by tenure in the ACS tables used. Instead, they are calculated as the residual:

V_category = T_category − O_category − R_category

where T is the total unit count (from B25024 or B25041), O is owner-occupied, and R is renter-occupied. The result is clipped to a minimum of zero.

Structure Type Dimension

Housing units are grouped into five structure type categories from ACS Tables B25024 (Units in Structure) and B25032 (Tenure by Units in Structure):

Bedroom Count Dimension

Housing units are grouped into four bedroom categories from ACS Tables B25041 (Bedrooms) and B25042 (Tenure by Bedrooms):

Processing Approach

The computation is fully vectorized — all geographies are processed simultaneously rather than in per-geography loops. For each structure type or bedroom category:

1. Owner counts are summed from the relevant B25032 (structure) or B25042 (bedroom) columns
2. Renter counts are summed from the corresponding renter columns in the same tables
3. Total counts are summed from B25024 (structure) or B25041 (bedroom)
4. Vacant counts are derived as total − owner − renter, clipped to zero
