These data are from the 2001 Residential Energy Consumption Survey (RECS) which provides information on the use of

energy in residential housing units in the United States. The RECS is a national statistical survey that collects energy-related

data for occupied primary housing units. RECS was first conducted in 1978; the eleventh and most recent survey was

conducted in 2001. In the 2001 RECS, data were collected from a sample of 4,822 households in housing units statistically

selected to represent the 107.0 million housing units in the United States. The RECS data are available for the four Census

regions, the nine Census divisions,and for the four most populous States--California, Florida, New York, and Texas.

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 These numbers could include a combination of Desktop and Laptop personal computers.

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.
