HHID '4-digit identification number' Columns 1-4 Included in all files Numerical Variable Variable length: 4 The variable HHID will be on all files. Each respondent is assigned an unique value of HHID. It can be used to merge data from one file with data from another file. Minimum Value: 1,001 Maximum Value: 8,111 NWEIGHT 'The Final Weight' Columns 6-11 Included in all files Numerical Variable Variable length: 6 Minimum Value: 2,096 Maximum Value: 78,559 The sample design for RECS is not a simple random sample. Consequently, to estimate the number or percent of households/housing units with a certain characteristic, the sampling weight should be used. The variable NWEIGHT is the sampling weight for the observation. It is approximately the inverse of the probability of selection. It gives the number of households that the response represents in the sample. For most categorical variables, the codebooks contain both the unweighted frequency and the weighted frequency. The unweighted frequency gives the number of observations, the weighted frequency gives survey estimate of the number of households/housing units for each possible value of the variable. The weighted frequencies are rounded to the nearest 100,000 households. This is the limit of the accuracy for RECS. When the unweighted frequency is less than 10 or the weighted frequency is less than 150,000; then weighted frequency is suppressed. A 'Q' is placed in the frequency to denote that the number is suppressed. This indicates that there are too few observation upon which to determine an accurate estimate.

The data were obtained using a shortened mail questionnaire. A hot-deck imputation procedure was used to match each mail respondent to a personal interview respondent. The critical matching variables were FUELHEAT, FUELH2O, TYPECOOL, TYPEHUQ, and REGIONC. Additional variables used in a scoring function to determine the best match were MONEYPY, NHSLDMEM, VEHICLES, HHAGE, and TOTROOMS. The remaining household/housing unit characteristics for the mail respondents were determined by the values of the matched personal interview respondent. The energy consumption and expenditures data for the mail respondents was based upon data obtained from their energy suppliers. It was not imputed using a hot deck procedure. Questionnaire data from personal interview respondents sometime is missing and needs to be imputed. 'Z' variables are used to indicate the presence of imputed data. For example, if ZURBRUR = 0 then URBRUR was not imputed. If ZURBRUR = 1 then URBRUR was imputed.

Heating degree days are the number of degrees the ADT is below the base temperature. To calculate daily degree days (base 65 degrees): ADT = (daily high + daily low)/2 CDD(daily) = 0 if ADT <= 65 = ADT - 65 if ADT > 65 HDD(daily) = 0 if ADT >= 65 = 65 - ADT if ADT < 65. Annual degrees days are calculated by summing the daily degree days. The .5 is carried over in the summation. The total is rounded up after the summation.

For each household that responded to the 1993 RECS, the annual amount of energy used for five end-use categories-- space heating, water heating, air- conditioning, refrigerators, and general appliance usage--was estimated. The end-use estimates were produced for each of the five main energy sources: electricity, natural gas, fuel oil, kerosene, and liquefied petroleum gas (LPG). The end-use amounts were not based on data produced by placing meters on individual appliances; rather, they were obtained by estimating how much of the total annual consumption for each energy source can be attributed to each of the end-use categories for each household by using a regression technique. The end-use estimates were normalized so that the sum of the end-use estimates was equal to the actual or imputed yearly consumption for each energy source used by the household. In particular: BTUEL = BTUELSPH + BTUELWTH + BTUELAPL + BTUELCOL + BTUELRFG BTUNG = BTUNGSPH + BTUNGWTH + BTUNGAPL + BTUNGCOL BTUFO = BTUFOSPH + BTUFOWTH + BTUFOAPL BTULP = BTULPSPH + BTULPWTH + BTULPAPL BTUKER = BTUKRSPH + BTUKRWTH + BTUKRAPL For all energy sources, the space-heating component was defined as all energy used to generate heat by space-heating equipment. The equipment could be the main space-heating equipment or secondary space-heating equipment. Hence, for all energy sources, a household could have had a positive amount of energy assigned to the space-heating component even if the energy source was not used as the main space-heating energy source. The component for water heating was defined as all energy used to heat water for hot running water, as well as water heated at point sources (such as stoves or auxiliary water-heating equipment) for bathing, cleaning and other noncooking applications of hot water. Energy used at point sources to heat water for cooking and hot drinks was considered part of the general appliance component, as was energy used to heat water for a swimming pool, hot tub, spa, or Jacuzzi. For electricity, end use estimates were also made for freezers, cooking, dishwashers, and clothes dryers. The estimates are BTUELFRZ, BTUELCOK, BTUELDWH, and BTUELCDR. BTUELAPL also includes these end uses, hence BTUELAPL equals the sum of BTUELFRZ, BTUELCOK, BTUELDWH, and BTUELCDR plus the consumption for lights and other numerous appliances. The electricity used in refrigerators is not included in BTUELAPL. BTUELAPL includes all electricity consumption except electricity use for space heating, water heating, air conditioning, and refrigerators. This includes electricity used for freezers, cooking, dishwashers, clothes dryers, lights, TV's, VCR's, stereos, coffee makers, power tools, pool heaters, furnace fans, home computers, and many more uses. BTUELSPH 'Electric Space Heat Use (Estimated) Columns 104-109 In 1,000's Of BTU' Numerical Variable Variable Length 6 For the 1987 and subsequent RECS, the electricity regression equation assigned the electricity associated with the operation of fans in any central forced-air heating equipment was assigned to the electricity appliance component and not to the space-heating component.

The electricity air-conditioning component was defined as all electricity associated with (1) electric air-conditioning equipment and (2) fans in any central air-conditioning equipment including natural gas air-conditioning equipment. The regression equations for electricity do not contain specific terms for whole-house fans, window fans, and evaporative (swamp) coolers. Hence, the consumption of electricity to operate these fans and evaporative coolers was not assigned to the air- conditioning component; it was included in the appliance component. There is a term for ceiling fans in the electricity appliance component. In the 1993 RECS, the households that reported that they had air-conditioning equipment but did not use the equipment, were assigned a value of zero for their electricity air-conditioning component.
