a Total 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.

b Households that use propane only for outdoor grilling are excluded from the RECS estimate of households using propane.

c Cooking includes fuels used by major cooking equipment (ovens, cooktops, and ranges).

Q = Data withheld because either the relative standard error (RSE) was greater than 50% or fewer than 10 households were in the reporting sample.

N = No households in reporting sample.
