1 The major fuels are electricity, natural gas, fuel oil, kerosene, and liquefied petroleum gas (LPG). 2 Includes only the space-heating expenditures of the space-heating fuel. Not included are: 1) the expenditures of the main space-heating fuel for uses other than space heating; 2) the expenditures of the main space-heating fuel where it is the secondary, and not the main, space-heating fuel, and; 3) the expenditures of other fuels that are used as secondary space-heating fuels. 3 Averages are for those households using each of the main space-heating fuels. 4 In previous RECS, square footage measurements were obtained during the personal interview. In the 1997 RECS, square footage was estimated using a regression equation developed with the 1993 RECS data. The 1997 RECS estimated square footage tends to be larger than the 1993 measured square footage. 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.
