1 The RECS cannot be used to accurately estimate the number of households that do not use electricity. 2 The averages for total and for appliances are over the set of all households; otherwise the averages are over the set of households using a given fuel or over the set using a given end use.

3 Households where the main or secondary space-heating fuel is electricity, natural gas, fuel oil, kerosene, or LPG.

4 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (0.9 million). It does include the small number of households where the fuel for central air-conditioning equipment was something other than electricity; those households were treated as if the fuel was electricity.

5 Households where the main or secondary water-heating fuel is electricity, natural gas, fuel oil, kerosene, or LPG.

NF = No applicable RSE row factor.

Q = Data withheld either because the Relative Standard Error (RSE) was greater than 50 percent or fewer than 10 households were sampled. Notes: To obtain the RSE percentage for any table cell, multiply the corresponding column and row factors. Because of rounding, data may not sum to totals. See "Glossary" for definition of terms used in this report.
