Legend:

The letter beside each estimate classifies its quality as follows: A–Acceptable, M–Use with caution, U–Too unreliable to be published.

Notes:

Valid skips indicate households whose heat was not supplied by a dwelling unit or did not use a furnace, boiler, or heat pump.
Due to rounding, the numbers may not add up and may differ slightly among tables.
