| 1Housing characteristics data were collected between August 2015 and April 2016. 2Total U.S. includes all primary occupied housing units in the 50 states and the District of Columbia. Vacant housing units, seasonal units, second homes, military houses, and group quarters are excluded. 3Total square footage includes all basements, finished or conditioned (heated or cooled) areas of attics, and conditioned garage space that is attached to the home. Unconditioned and unfinished areas in attics and attached garages are excluded. The square footage for some housing units was calculated based on measurements taken by the interviewer. For households responding without the presence of an interviewer, square footage was imputed based on characteristics of the housing unit. See 2015 RECS Square Footage Methodology for full details about data collection and processing. Q = Data withheld because either the Relative Standard Error (RSE) was greater than 50% or fewer than 10 households responded. Notes: Because of rounding, data may not sum to totals. See RECS Terminology for definition of terms used in these tables.
