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 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million

households using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 4 Includes LPG and natural gas.

cf = Cubic feet.

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.

1 New construction for 2001 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 (2.1 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 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million households

using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 4 Includes LPG and natural gas.

cf = Cubic feet.

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.

1 Below 150 percent of poverty line or 60 percent of median State income. 2 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million households

using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 4 Includes LPG and natural gas.

1 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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. 2 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both

central air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3

million households using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 3 Includes LPG and natural gas.

cf = Cubic feet.

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.

1 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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. 2 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both

central air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3

million households using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 3 Includes LPG and natural gas.

cf = Cubic feet.

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.

1 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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. 2 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million households

using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 3 Includes LPG and natural gas.

cf = Cubic feet.

NE = RSE row factor not estimated because RSE’s for all statistics in this row are between 0.0 and 1.0 percent.

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.

1 Based on the household respondent’s description rather than the Federal Government definition. 2 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million households

using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 4 Includes LPG and natural gas.

cf = Cubic feet.

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.

1 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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. 2 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million

households using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 3 Includes LPG and natural gas.

cf = Cubic feet.

NE = RSE row factor not estimated because RSE’s for all statistics in this row are between 0.0 and 1.0 percent.

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.

1 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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. 2 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million households

using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 3 Includes LPG and natural gas.

cf = Cubic feet.

NE = RSE row factor not estimated because RSE’s for all statistics in this row are between 0.0 and 1.0 percent.

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.

1 The number of households, where the end use is electric air-conditioning, does not include households that did not use their equipment (2.1 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. 2 The 2001 RECS reported 800,000 households having both central air-conditioning and room/wall air-conditioners, with 600,000 households using both central

air-conditioning and 200,000 households using only room/wall air-conditioners. These room/wall air-conditioners are not included in the count of 23.3 million

households using room/wall air-conditioners. Note: This applies to all occurrences of central air-conditioning. 3 Includes LPG and natural gas.

cf = Cubic feet.

NE = RSE row factor not estimated because RSE’s for all statistics in this row are between 0.0 and 1.0 percent.

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.
