(1)  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.
(2)  Based on the household respondent's description rather than the Federal Government definition.
(3)  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.
(4)  Estimates provided by the household interview respondents, who were asked which category best described the total heated
floorspace in the home.
(5)  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.
(6)  Below 150 percent of poverty line or 60 percent of median State income.
(7)  Includes 5.5 million householders who described themselves as Hispanic rather than White, Black, or other.
(8)  For these buildings we assumed 16 units, the median value of the reported cases.
(*) = Value rounds to zero in the units displayed.
Q = Data withheld either because the Relative Standard Error (RSE) was greater than 50 percent or fewer than 10 households were
sampled.
Notes:  • Because of rounding, data may not sum to totals.
