1 New construction for 1997 includes only those housing units built and occupied between January and the April-August period when the household interviews were conducted. 2 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. 3 Includes 642,000 households using room/wall air-conditioners in addition to central air-conditioning. These room/wall air-conditioners are not included in the count of 25.2 million households using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 4 Averages are for those households using any electric air-conditioning, central air-conditioning, or room/wall air-conditioning, as applicable. 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. 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.
