1 One of five climatically distinct areas, determined according to the 30-year average (1961-1990) of the annual heating and cooling degree-days. For this report, the

heating or cooling degree-days are a measure of how cold or how hot a location is over a period of one year, relative to a base temperature of 65 degrees Fahrenheit. A

household is assigned to a climate zone according to the 30-year average annual degree-days for an appropriate nearby weather station. 2 Estimates provided by the household interview respondents, who were asked which category best described the total heated floorspace in the home. 3 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. 4 Based on the household respondent’s description rather than the Federal Government definition.

(*) = Value rounds to zero in the units displayed.

-- = Data not applicable.

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.
