* Procedures for associating weather data acquired from NOAA with individual sample
housing-units have evolved over the life of the survey. A major change occurred in
the 1987 RECS, when degree-day information for each housing-unit in an SSU was
taken from the individual weather station nearest (in terms of distance and other
factors) to the SSU, provided usable data were available for that station. Prior to
1987, degree-day data had been based on clusters of weather stations within a NOAA
weather division.
Estimation Procedures
- For each RECS, part of the estimation procedure has been to benchmark the survey
estimates of the number of households in various subgroups to agree with independent
estimates derived from the Census Bureau's Current Population Survey (CPS).
Initially, this ratio estimation procedure was carried out separately for 12 cells based
on Census region and location type (central city, suburban, rural). Early analyses
showed that RECS estimates of one-person households were low, so in the 1982 RECS
a preliminary step was added in which the estimates were benchmarked to CPS
estimates for three categories: single-person households with mate householders,
single-person households with female householders, and all other households. In the
1993 RECS, a further benchmark adjustment was introduced to ensure agreement of
RECS and CPS household estimates for the nine Census divisions and for four large
States: California, Florida, New York, and Texas.
- For all surveys through 1990, the CPS-based estimates used as benchmarks for the
RECS estimates of households were developed for November of the survey year,
representing the approximate midpoint of the data collection period for the Household
Survey. In the 1993 RECS, the benchmark month was changed to July of the survey
year, to coincide with the midpoint of the reference period for energy consumption.
* Measured total consumption of each fuel is allocated to end-use categories by use of
a model-based estimation procedure that relates end-use consumption to a variety of
housing and household characteristics for which information is obtained in the survey.
The allocation model has been gradually refined in successive surveys. A major shift
occurred in the 1984 RECS, when a nonlinear regression model replaced the linear
model used in the earlier surveys (Carroll 1987). The number of separate end-use
categories estimated for electricity was increased in 1990 and again in 1993.
Data Disoomlnatlon
* Starting with the 1980 RECS, there have been two major publications of the results
from each survey, the first covering Housing C/wracterisfes 1993 and the second
covering Household Energj Consunupfon and Expenditures 1993. In 1984, for the
first time, estimates of energy consumption by end use were included in the regional
supp leent to the Househol Eergy Conumption and Expenditres 1993 report.
