Executive Summary

This report presents findings from the Residential Transportation Energy 

Consumption Survey (RTECS) conducted in 1985. This survey was designed by the 

Energy Information Administration to provide information on motor fuel 

consumption and expenditures by households in vehicles for personal use. The 

principal findings from the survey are as follows:

o In 1985, 77.7 ( 1.1) million households (or 89 ( 1) percent of all 

households) had the regular use of a vehicle for personal 

transportation. For households using vehicles, the average was 1.8 

vehicles per household.

o Household vehicles use consumed 10.5 ( 0.6) quadrillion Btu, or 14 

percent of the total U.S. energy consumption of 73.8 quadrillion 

Btu. Household vehicle consumption accounted for about one-third of 

U.S. petroleum consumption and about one-half of total fuel 

consumption by the transportation sector.

o The average household that used a vehicle consumed 1,079 ( 38) 

gallons of motor fuel. This 1985 consumption level was not 

statistically significantly different from the level estimated in 

the RTECS for 1983. Average household expenditures for motor 

vehicle fuel were $1,274 ( 42), and the average price paid was $1.18 

( 0.01) per gallon, which was not significantly different from the 

average price paid in 1983.

o Household characteristics (such as family income, the size of the

household, and the number of vehicles used by the household) were more 

strongly related to variations in motor fuel consumption than was 

geographic location by Census region.

o Total mileage in personal vehicles increased in 1985 over the 1983 

figure, but the increase was primarily due to the increase in the 

number of households with vehicles. The average number of miles per 

vehicle, 9,855 ( 270), and the average total number of miles per 

household, 17,402 ( 546), were not significantly changed from their 

1983 values.

o Average fuel efficiency for all vehicles increased by 7 ( 3) percent 

from 1983. The average efficiency was 16.1 ( 0.3) miles per gallon 

in 1985 and 15.1 ( 0.2) in 1983. The overall fuel efficiency 

increased because older cars in the total fleet were replaced by 

newer cars. However, for model years after 1982, the average fuel 

efficiency was fairly constant.

Energy Information Administration vl1
1. Introduction

This report presents data collected in the 1985 Residential Transportation 

Energy Consumption Survey (RTECS). The survey was designed by the Energy 

Information Administration (EIA) to provide information on how energy is 

used by households for personal vehicles. It is an integral part of a series 

of surveys designed by the EIA to collect data on energy used by households. 

Data from the surveys are available to the public through published reports 

such as this one and through public use data tapes. The RTECS collects data 

on the number and type of vehicles used by the household. For each 

vehicle, data are collected on the number of miles traveled for the year, 

the number of gallons of fuel consumed, the type of fuel used, the price 

paid for fuel, and the number of miles per gallon.

The RTECS sample, which consists of 4,020 households, was drawn from a larger 

sample selected for participation in the 1984 Residential Energy Consumption 

Survey (REGS). Households were interviewed for the REGS in fall 1984. The REGS 

collected data on the ways energy is used within the home, including heating 

fuel(s), the types of appliances, and conservation practices. Actual energy 

bills for these households were obtained from fuel suppliers for April 1984 

through March 1985. These data are presented in a series of residential energy 

consumption reports (See Appendix F). For those households that participated in 

both the RECS and RTECS, data are available on energy used within the home as 

well as energy used in personal vehicles. However, the time periods of 

consumption for these two components of energy use do not fully overlap. The 

transportation data represent energy consumed in personal vehicles during 

calendar year 1985; household data represent energy consumed in the home from 

April 1984 through March 1985.

There are small differences between the home energy use data presented in 

the RECS reports and the home energy use data presented here as part of 

this transportation report. These differences exist because the transportation 

sample is a subsample of the households that participated in the RECS. 

Furthermore, the RECS sample was weighted to represent the number of U.S. 

households as of November 1984; the RTECS sample has been weighted to represent 

the number of U.S. households as of July 1985. Therefore, in this report, all 

survey statistics for number or percentage of households are estimates as of the 

July 1985 reference point. Although the statistics in this report are stated 

for calendar year 1985, they do not account for growth in the housing stock and 

the resulting growth in the vehicle stock which occurred from July through 

December 1985.

Reports are available from the National Energy Information Center or U.S. 

Government Printing Office (see inside front cover). Public-use data 

tapes are available from the National Technical Information Service, 

Computer Products Division, 5285 Port Royal Road, Springfield, Virginia 

22161 (Telephone: 703-487-4808).

2 A household is a family or group of unrelated persons occupying the same

housing unit. This corresponds to the U.S. Bureau of the Census definition. 

(See Glossary.)

Energy Information Administration
2. Size and Composition of the Vehicle Stock

In 1985, 77.7 ( 1.1) million or 89 ( 1) percent of all U.S. hgugeholds owned or 

had the regular use of a vehicle for personal transportation. ' These 

households owned or had the use of an average of 137.3 ( 3.2) million vehicles. 

Automobiles, including station wagons, were the most prevalent body style, 

comprising 78 ( 1) percent of household vehicles. Pickup trucks, the second 

most common vehicle type, comprised 15 ( 1) percent, while vans and jeep-like 

vehicles (see Glossary) each comprised 3 ( 0.5) percent.

The number of different vehicles in use by households changes throughout the 

year, as households acquire and dispose of vehicles. In 1985, 46 ( 2) percent 

of all households using vehicles had either acquired one or more vehicles, or 

disposed of one or more vehicles, or both. For most of these households, only 

one vehicle was acquired during the year, or one vehicle was disposed of during 

the year, or both. Also within more than half of these households, both 

acquisition and disposal of vehicles occurred.

In 1985, households acquired a total of 34.6 ( 1.7) million vehicles and 

disposed of 37.3 ( 2.1) million vehicles. However, the net change in vehicle 

stock due to vehicle acquisition and disposal was not statistically significant.

3 The value in parentheses after a statistic represents a 95-percent

confidence interval; that is, it represents 1.96 times the standard error of the 

statistic. The standard error is a measure of the variability of an estimate 

that is based on a sample survey. A 95-percent confidence interval can be 

calculated by multiplying 1.96 times the standard error: subtracting this value 

from the statistic gives the lower end of the interval, and adding this value to 

the statistic gives the upper end. A 95-percent confidence interval means that 

if the survey were repeated under the same conditions using all possible 

samples, 95 percent of the surveys would yield intervals that contained the true 

value of the statistic. Nonsampling error and bias due to nonresponse is an 

additional concern regarding the statistics in this report. For further 

information on evaluating the data, see Appendix B.

Household vehicles include company owned cars if regularly available to 

household members for personal transportation and cars rented or leased for 1 

month or more. (See Glossary.)

This average was computed by adding together the number of days each 

different vehicle was available to a household during the year and dividing the 

sum by 365. The resulting figure was aggregated across all households. The 

total number of distinct vehicles used by hoxiseholds would exceed 137.3 million.

RTECS: Consumption Patterns of Household Vehicles 1985 ~ 

Energy Information Administration
The average number of vehicles owned by or available to a household 

during 1985 was 1.8 ( 0.04). Of the 77.7 million households having use 

of a vehicle, 5 (±1) percent had an average of less than one vehicle for 

the year, 31 ( 2) percent averaged 1 vehicle for the year, and 15 ( 1) 

percent averaged between 1 and 2 vehicles. Another 25 ( 2) percent of 

the households averaged 2 vehicles, and the remaining 23 ( 2) percent 

averaged more than 2 vehicles for the year (Table 3).

Purchasing motor fuel—Fuel expenditures for personal transportation totaled $99.1 billion in 1985.

This is the effective number of vehicles in a household's possession 

for a full year. For example, a household that owned two vehicles, one 

each for one-half of a year, would effectively possess an average of one 

vehicle for the year.

of this report.

3. Aggregate Consumption, Expenditures, and 

Types of Fuel for Household Vehicles

o

In 1985, U.S. energy consumption of all fuels was 73.8 quadrillion Btu. Of 

this total, household vehicles consumed 10.5 ( 0.6) quadrillion Btu, or 14 

percent (See Glossary for Btu conversion factors). Household vehicle fuel 

consumption in 1985 accounted for about one-third of U.S. petroleum consumption 

and about one-half of the total fuel consumption in the transportation sector 

(10.5 quadrillion Btu out of 19 quadrillion Btu) (Figure 1).

The 10.5 quadrillion Btu consumed in household vehicles in 1985 represented 83.9 

( 4.4) billion gallons of motor fuel (i.e., gasoline, diesel fuel, and gasohol). 

This consumption was not significantly different from the 80.3 ( 4.7) billion 

gallons consumed in 1983. In 1985, expenditures for motor fuel totaled $99.1 

( 5.1) billion. Gasoline accounted for 82.4 ( 4.7) billion gallons or 98 ( 1) 

percent of the 83.9 billion gallons of motor fuel consumed for personal 

transportation. Expenditures for gasoline totaled $97.2 ( 5.3) billion. Of the 

82.4 billion gallons of gasoline consumed, 70 ( 3) percent was unleaded and 30 

( 3) percent was leaded. In 1983, only 59 ( 3) percent of the gasoline consumed 

in household vehicles was unleaded, and 41 ( 3) percent was leaded (Figure 2).

In addition to the 82.4 billion gallons of gasoline consumed in 1985, 

residential vehicles also consumed 1.5 ( 0.5) billion gallons of diesel fuel.

4. Average Household Consumption of

Motor Fuel

In 1985, there were 77.7 (±1.1) million households which owned or had use of at 

least one vehicle for at least part of the year. These households contained 

215.1 (±6.3) million members; 145.2 (±3.7) million of these were drivers. Thus, 

the average was 1.9 (±0.04) drivers per household.

In 1985, an average of 1,079 (±38) gallons of motor fuel were consumed per 

household with vehicles, and an average of 578 (±19) gallons were consumed per 

driver. The amount consumed per household had not changed significantly from 

1983, when 1,112 (±41) gallons were consumed per household (Figure 3).

Note: Data in this figure include only households with motor vehicles for personel transportation. 

Source: Energy Information Administration, Office of Energy Markets and End Use, Energy End Use Division, 

1983 and 1985 Residential Transportation Energy Consumption Surveys.

The consumption of motor fuel per household was different for different Census 

regions (Table 3). There were 972 (±84) gallons consumed per household in the 

Northeast, 1,070 (±67) gallons per household in the North Central region, 1,137 

(±62) gallons in the South, and 1,095 (±88) gallons in the West. However, only 

the difference between the Northeast and South was statistically significant. 

Household characteristics such as family income, the size of the household, and 

the number of vehicles in the household were strongly related to fuel 

consumption per household. Lower income households consumed less than higher 

income households. Consumption ranged from 645 (±216) gallons per household for

RTECS: Consumption Patterns of Household Vehicles 1985 g 

Energy Information Administration
families with income of less than $5,000, to 1,406 (±66) gallons for families 

with income of $35,000 or more. Consumption per household was positively 

correlated with family size, ranging from 628 (±86) gallons for 1-person 

households to 1,450 (±99) for households with 5 or more persons. Household 

consumption was roughly proportional to the number of vehicles in the household. 

For example, households with an average of 1 vehicle consumed 569 (±50) gallons 

of motor fuel. Households with 2 vehicles consumed a little more than twice as 

much, 1,225 gallons (±65).

The age of the householder (see Glossary) seemed to affect consumption only when 

the householder was 60 years and older. For other categories of age of 

householder, consumption was relatively close to the average for all U.S. 

households with vehicles. Households in which the householder was 60 years 

and older consumed 698 (±53) gallons, compared with 1,079 (±38) gallons 

for the average household. Older householders had the fewest vehicles 

and the lowest vehicle fuel efficiency of any householder age category. 

However, the factor that distinguishes these households more than any 

other was their lower than average annual mileage, 10,972 (±882) compared 

to 17,402 (±546).

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
5. Average Household Expenditures for

Motor Fuel

Households that had the regular use of a vehicle spent an average of $1,274 

C ± 42) for motor vehicle fuel in 1985. In addition, these same households spent 

$1,145 (±29) for fuels used in the home for purposes such as heating and cooking 

(Table 13). Thus, total energy expenditures were $2,419 (±57) per household, 53 

(±2) percent of which was spent on motor fuel, and 47 (±2) percent of which was 

spent on fuels used in the home. In 1983, transportation energy expenditures 

accounted for 55 (±3) percent of total household energy expenditures.

Expenditures per household for motor fuel appeared to be slightly higher in the 

South and West Census regions than in other regions, but the differences were 

not statistically significant. Expenditures per household for motor fuel were 

$1,169 (±99) in the Northeast, $1,266 (±77) in the North Central region, $1,321 

(±70) in the South, and $1,304 (±100) in the West. Therefore, differences 

across Census regions in total household energy expenditures were due mainly to 

expenditures for nontransportation fuel used in the home (Figure 4). Across 

Census regions, the pattern of expenditures for motor fuel mirrored the pattern 

of consumption. (See Table 3 and Chapter 4.)

The average price paid for motor fuel in 1985 remained approximately the same as 

in 1983, $1.18 (±0.01) per gallon. Unleaded gasoline reflected this stability, 

with an average price of $1.21 (±0.01) in 1985 and $1.22 (±0.01) in 1983. The 

average price of leaded gasoline decreased slightly, from $1.14 (±0.01) in 1983 

to $1.11 (±0.01) in 1985 (Table 2). The percentage of unleaded gasoline 

consumption grew from 59 (±2) percent in 1983 to 70 (±2) percent in 1985.

9 Expenditures for motor fuels were estimated from the 1985 RTECS, while

expenditures for fuels used in the home were estimated from the 1984 RECS. 

Although the households participating in RTECS were subsampled from RECS, the 

reference periods for these surveys only partially overlapped. The assumption 

has been made of enough stability in expenditures over these 2 years to allow 

the summing of expenditures for household fuel and motor fuel. See the 

Introduction and Appendix A for more details on the relationship between the two 

surveys.

6. Total Mileage and Average Mileage

per Household

In 1985, personal vehicles were used to travel a total of 1,353 (±66) billion 

miles. This represents an 11 (±7) percent increase over the 1,215 (±52) billion 

miles traveled in 1983.

Most of the 11 percent increase in total miles driven can be accounted for by an 

8 (±2) percent increase in the number of households with vehicles (Table 3), and 

a corresponding 6 (±4) percent increase in the total number of vehicles. The 

increase in mileage was apparently not due to a change in motor vehicle use 

patterns. In 1985, an average of 9,855 (±270) miles were driven per vehicle, 

and an average of 17,402 (±546) miles were driven per household. These motor 

vehicle use patterns had not changed significantly since 1983 (Figure 5).

Two percent of the growth since 1983 in the number of households with 

vehicles is attributable to a change in the definition of car-owning households 

for the 1985 report. For this report we have included households that owned a 

vehicle at any time during 1985. For the 1983 report, only households that 

owned a car as of July 1983 (the date for which population control totals are 

set for all U.S. households) were considered vehicle-owning households.

It appears that more miles were driven per household in the West and South 

Census regions, than in the Northeast and North Central regions. An average of 

18,086 (±1,028) miles were driven per household in the West, and 17,991 (±811) 

miles per household in the South. In the Northeast, 16,476 (±1,647) miles were 

driven per household, and in the North Central region, 16,734 (±1,050) miles 

were driven per household. However, the differences between Census regions were 

not statistically significant. A larger sample size would be needed to 

statistically distinguish regional differences in vehicle use patterns.

7. Fuel Efficiency

Fuel efficiency averaged for all vehicles, measured in miles per gallon or MPG, 

was 16.1 (±0.3) MPG in 1985. This represents a 7 (±3) percent increase over 

the 15.1 (±0.2) MPG estimated for 1983. Because of this increase in vehicle 

efficiency, total consumption of motor fuel did not increase significantly 

between 1983 and 1985, even though total mileage driven did increase 

significantly.

Federal Highway Administration statistics on fuel efficiency indicate 17.9 MPG 

for 19§5, and 16.7 MPG for 1983, averaged for all United States passenger 

cars. *~ This increase over time is similar in magnitude to the increase 

estimated by RTECS. The RTECS estimates of MPG are slightly lower than those of 

FHA, in part because RTECS includes data for vans and trucks, whereas the FHA 

statistics are generally oriented toward passenger cars.

The overall MPG increased through time because as older vehicles were retired 

from the national residential fleet, they were replaced by newer, more fuel 

efficient vehicles. Figure 6 shows a steady improvement in fuel efficiency over 

model years 1974 through 1982. Vehicles of model years 1974 to 1978 had an 

average fuel efficiency of 13.8 (±0.4) MPG, while vehicles of model years 1981 

to 1982 attained an average of 19.1 (±0.5) MPG. For model years after 1982, 

however, the average MPG was fairly constant (Figure 6 and Table 8).

Vehicles of newer vintage were apparently driven more in 1985 than were older 

vehicles. Vehicles of model year 1985 or later were driven 13,007 (±1,020) 

miles per vehicle, while vehicles of model year 1973 or earlier were driven 

6,859 (±847) miles (Figure 7). Because newer vehicles were more fuel efficient, 

however, they did not consume as much fuel as might be expected, given their 

greater use (Figure 8).

The number of cylinders in a vehicle's engine was an important determinant of 

fuel efficiency. In general, the fewer the number of cylinders, the higher the 

fuel efficiency (Figure 9).

Fuel efficiency was related to vehicle type (automobile, pickup truck, and van) 

probably as a result of the different engine sizes and body weights found in 

these vehicle types. Automobiles averaged 17.2 (±0.3) MPG, pickup trucks 

averaged 13.5 (±0.5) MPG, and vans averaged 13.2 (±1.0) MPG (Figure 10). 

Automobiles consumed less fuel per vehicle in 1985 than did pickup trucks or

Miles per gallon (MPG) for all vehicles in a subgroup, such as the whole 

United States or a given Census region, is computed as the ratio of total miles 

traveled by all vehicles in that subgroup, divided by the total gallons consumed 

by all vehicles in the subgroup. It is not an arithmetic average of the 

individual MPG's achieved by the vehicles in the subgroup.

vans, despite the fact that there were no significant differences in miles 

driven in 1985 between automobiles, pickup trucks, and vans (Figure 11 and Table 

8). The lower consumption per automobile in 1985 was due to the higher fuel 

efficiency of automobiles.

An estimated 63 (±2) percent of household vehicles had air conditioning in 1985. 

There was no significant difference in fuel efficiency between air-conditioned 

vehicles, 16.0 (±0.3) MPG, and non-air-conditioned vehicles, 16.3 (±0.5) MPG.

An estimated 72 (±2) percent of vehicles had automatic transmissions in 1985, 

while only 28 (±1) percent had manual shift transmissions. However, the fuel 

efficiency of vehicJ.es with automatic transmissions averaged only 15.1 (±0.3) 

MPG, compared to vehicles with manual transmissions, which averaged 19.3 (±0.9) 

MPG (Table 8). Although a significant part of this difference in MPG may be 

directly caused by transmission type, other factors correlated with transmission 

type, may also influence MPG. Engine size could be such a factor.

8. Detailed Statistics

The following 13 tables provide summaries of the 1985 RTECS data on such 

residential transportation parameters as miles driven, gallons of fuel consumed, 

expenditures for fuel, and price per gallon. Also presented are actual or 

"in-use" fuel efficiencies in miles per gallon (MPG). These statistics are 

broken out according to (1) various characteristics of the households owning the 

vehicles, and (2) various characteristics of the vehicles themselves. The 

household and vehicle characteristics are represented by the different table 

rows. In all tables of this report, the term "automobile" includes station 

wagons. See the Glossary for definition of terms used in the tables.

Table 1 presents national totals for miles driven, gallons of fuel consumed, and 

motor fuel expenditures, by various household and vehicle characteristics. 

Table 2 contrasts leaded and unleaded gasoline in terms of gallons consumed, 

price per gallon, and MPG, for different vehicle characteristics.

Table 3 displays statistics on a per household basis; for example, number of 

vehicles per household, number of gallons consumed per household, miles driven 

per household, and expenditures per household. These statistics are computed as 

ratios. For example, miles driven per household is calculated by dividing the 

total miles driven by the corresponding total number of households. Table 3 

also contains ratios for MPG, expenditures per gallon, and expenditures per 

mile. Table 8 is similar to Table 3, except that the ratios are computed on a 

per vehicle-year basis. For example, miles driven per vehicle is calculated by 

dividing the total miles driven by the effective number of vehicles. 

Consequently, a household that only owned one automobile for 6 months and drove 

it 5,000 miles would have a value of 10,000 miles per vehicle-year.

Table 4 shows the distribution of motor fuel expenditures per household. The 

distribution is presented as percentages in each of five motor fuel expenditure 

categories. Tables 5, 6, and 7 are similar except that the categories deal with 

gallons consumed per household, miles driven per household, and MPG for the 

household. The MPG for a given household is the ratio of total miles to total 

gallons consumed, for all vehicles in that household. Tables 9, 10, 11, and 12 

are similar to Tables 4 through 7, except that they contain the percentage 

distribution of vehicles, and the categories deal with motor fuel expenditures 

per vehicle (Table 9), gallons consumed per vehicle (Table 10), miles traveled 

per vehicle (Table 11), and vehicle MPG (Table 12).

Table 13 is unique in that it shows the expenditures of households for energy 

used in the home, combined with expenditures for motor vehicle fuel. That is, 

all residential sector energy expenditures are combined: home heating and 

cooling, water heating, appliances, and motor vehicle fuel. Table 13 presents 

the total energy consumption and expenditures in the residential sector, listed 

by various characteristics of households.

Relative Standard Errors (RSE's) for the statistics in Tables 1 through 13 are 

found in Tables Bl through B13 of Appendix B. There is a one-to-one 

correspondence between the values in Tables 1 through 13 and the RSE's in 

Tables Bl through B13. Appendix B gives information on the meaning and use of 

RSE's as measures of reliability.

How the Survey Was Conducted

Introduction

The purpose of the RTECS is to obtain information on energy consumption and 

related matters for vehicles operated for personal transportation by members of 

residential households in the United States. It is a companion survey to the 

Residential Energy Consumption Survey (REGS), which collects information for 

residential households in the United States on energy consumption and 

expenditures within the housing unit and on housing characteristics. Both of 

these surveys are conducted by the Energy Information Administration (EIA) of 

the U.S. Department of Energy (DOE).

The 1985 RTECS is the second such survey covering a calendar year conducted by 

EIA. (The first RTECS was for 1983.) Subsequent surveys will be conducted 

triennially, with the next one scheduled for 1988. Previously, monthly surveys 

were conducted from June 1979 to September 1981.

Survey Forms and Collection Procedures

The overall objective of the RTECS is to provide a database containing 

information for calendar year 1985 on the number and types of vehicles per 

household, and for each vehicle: annual mileage, gallons of fuel consumed, type 

of fuel used, price paid for fuel, and fuel efficiency. This requires for each 

vehicle, the collection of background information, odometer readings at the 

beginning and end of the year, and fuel-purchase data.

Three separate forms were used to collect these data. Form EIA-429, the 

Background Questionnaire, was used to update the information obtained on the 

REGS concerning vehicles in use by the household in 1985. This form collected 

information on the number of vehicles, and for each vehicle, the body type, 

make, model, and model year. Form EIA-141 consisted of two parts, a set of 

cards that were used to obtain beginning- and end-of-year odometer readings and 

a monthly fuel purchase log.

The Background Questionnaire was administered primarily by telephone, although 

these data were occasionally collected by mail or personal visit when a 

telephone contact could not be successfully completed. The background 

information was collected in December 1984 for the majority of the units in the 

RTECS sample and was updated during the middle of 1985. Some households were 

not contacted until later because the RECS interview was not completed by 

December 1984.

For the majority of the units in RTECS, the odometer reading cards (one for each 

vehicle) were mailed in December 1984. The respondents were instructed to enter 

the vehicle's odometer reading on this card after the last use of the vehicle on 

a specified date. For the majority of the units, the date was between December 

31, 1984 and January 15, 1985. These cards were retained by the respondents and 

the information was obtained from them by telephone.

Respondents were assigned to monthly panels by means of a sampling procedure 

decribed below. Fuel-purchase data for an assigned calendar month during 1985 

were collected on the fuel-purchase log. In addition to beginning- and 

end-of-month odometer readings, this form obtained for each purchase: the date, 

vehicle mileage, number of gallons purchased, total cost of fuel, price per

RTECS: Consumption Patterns of Household Vehicles 1985

Energy Information Administration 67
gallon, whether the tank was filled, type of fuel used (gasoline, diesel, or 

gasohol), and if gasoline, whether leaded, unleaded, or premium. Information 

from the completed log was collected by telephone.

End-of-year odometer readings were obtained from all respondents in a manner 

similar to the procedures used for obtaining the beginning-of-year readings.

The Target Population and the Sample

The target population for the RTECS was estimated at 87.3 million households in 

the 50 States and the District of Columbia as of July 1985. Basically, a 

household is defined as a housing unit occupied by an individual, a family, or a 

group of up to nine unrelated persons. (See the Glossary for a more comprehen 

sive definition.) The RTECS uses the same definition of household as does the 

U.S. Bureau of the Census.

The RTECS sample was designed to be representative of this target population. 

The respondents were a subsample of the households selected for the 1984 RECS 

sample. Therefore, before describing this subsampling procedure, it is useful 

to briefly describe the RECS sample. Full details on the RECS sampling proce 

dures are available in Residential Energy Consumption Survey: Housing 

Characteristics 1984, DOE/EIA-03l4(84).

The RECS sample is a multistage area probability sample with the ultimate 

sampling unit being the household. The original RECS sample consisted of 7,658 

units. Of these, 123 units were either not used for dwelling purposes or were 

not habitable. An additional 783 units were ineligible because of a current 

vacancy or seasonal occupancy. Of the 6,752 eligible units, information on 

housing characteristics was successfully collected from 5,682 for a response 

rate of 84.2 percent.

The RECS sampling procedures were designed to permit the observation of changes 

in certain individual housing units over the period between two data collection 

cycles. It was not desirable, however, to sample the same units cycle-aftercycle because this approach is unduly burdensome to the respondent. Therefore, 

a rotation plan was developed that resulted in approximately one-half of the 

total sample being included in any two contiguous cycles.

The households to be included in the RTECS were subsampled from the 5,682 RECS 

units for which data were successfully collected. The general plan for 

selecting the RTECS sample was to subsample a national core sample of all 

households and to supplement this core sample with additional households whose 

total annual vehicle mileage was "average and above." This plan essentially 

oversampled those households that accounted for the largest portion of total 

vehicle mileage and resulted in a more efficient design for obtaining 

fuel-purchase data.

The target sample size for the RTECS was initially set at 3,850 households. The 

next step was to allocate this total sample to the core samp]e and the supplemen 

tary sample. A core sample of 3,200 households represented a sampling rate of 

545 per 10 million households, the lowest sampling rate for any part of the 1984 

RECS sample.. This left an additional 650 households to be included in the

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
supplementary "average and above" sample. In order to determine which house 

holds should be included in this supplement, the responses to the REGS question 

on estimated vehicle mileage were aggregated to the household level. An 

empirical analysis of these aggregated data from the first 2,000 responses to 

REGS indicated that if households that traveled 12,500 miles in the previous 12 

months were sampled at a rate of 1,288 per 10 million households, then the 

required 650 households would be added. This sampling rate is equal to the 

highest sampling rate for the REGS excluding Alaska, low-income areas, and other 

selected primary sampling units. The total RTECS sample obtained in this manner 

was 4,020 households, 170 more than the original target. This increase was due 

to the slightly higher REGS sample size than was originally planned.

Once the basic RTECS sample had been selected, a systematic random procedure was 

used to assign the households to one of the 12 months of 1985 for reporting fuel 

purchases. This procedure limited the reporting burden of each household to a 

single month, while preserving the seasonality inherent in fuel purchase 

patterns.

Survey Estimates

Survey estimates were developed to project the RTECS sample results to the 

target population. This required the development of weights for each sample 

household using a multistage weighting procedure. The weights for the RTECS 

were developed from the weights that originally had been used in the 1984 REGS. 

These original weights were divided by the probability that a household was 

selected into the RTECS sample. These selection probabilities were determined 

by a ratio of the sampling rate for the RTECS to the original sampling rate 

appropriate for that household in the 1984 REGS. For cases in which the value 

of this ratio exceeded 1.0, a value of 1.0 was substituted.

These initial approximations of the RTECS weights were appropriate for estimates 

of U.S. households as of November 1984 (the midpoint of the REGS data collection 

time period). Since the midpoint of the RTECS data collection period was July 

1985, additional adjustments were necessary. These RTECS weights were adjusted 

in three steps using data from the Current Population Survey (CPS). Each step 

consisted of a ratio adjustment using household characteristics, so that the 

resulting number of RTECS households (that is, the sum of the RTECS weights) 

matched the CPS control totals of the number of households in the categories 

included in each step.

In the first ratio adjustment step, the RTECS sample was categorized by the four 

Census regions and by metropolitan status (in a center city of an Metropolitan 

Statistical Area (MSA), in an MSA but not in the center city, and not in an 

MSA). Because the breakdowns by community type were not available from the 

March 1985 CPS (at the time the weighting was completed), the controls for 

region by metropolitan status were extrapolated from the March 1983 and March 

1984 CPS and then adjusted to match the estimated July 1985 regional totals.

In the second ratio adjustment, the RTECS sample was categorized by type of 

household (one-person male household, one-person female household, and all other 

household types). This step was used to adjust for the lower response rates for 

one-person households.

RTECS: Consumption Patterns of Household Vehicles 1985 , 

Energy Information Administration
The third ratio adjustment used the same categories as the first ratio 

adjustment.

The final weights, after the application of the three ratio adjustments, reflect 

estimates of total households as of July 1985.

Nonresponse to the Survey

Nonsampling errors and bias are sources of variability due to the conduct of the 

survey. These can include population undercoverage during sampling, response 

bias, interviewer error, coding and/or key punching error, and nonresponse bias. 

The wording and format of the survey questionnaires, the procedures used to 

select and train interviewers, and the quality control procedures built into the 

data collection and processing operations were all designed to minimize these 

sources of error.

The RTECS required substantial participation from households throughout the 

survey year of 1985, above and beyond their prior participation in the REGS. As 

previously described, background information was obtained in December 1984 and 

again at midyear. In addition, beginning- and end-of-year odometer readings 

were obtained, and fuel purchases were recorded for 1 of the 12 months during 

1985. These diverse needs necessitated numerous telephone and mail contacts 

with the respondents. Such ongoing participation adversely affects survey 

response. In order to improve participation, cash incentives were provided to 

the respondents throughout the year. Households received one dollar for 

beginning- and end-of-year odometer readings, and five dollars for each monthly 

vehicle log completed.

Because the RTECS sample was selected from REGS respondents, in no case were 

data for a respondent totally absent. In fact, the REGS weights that formed the 

basis for the RTECS weights included a nonresponse weight adjustment that which 

is reflected in the RTECS weights. There were instances in the RTECS, however, 

where it was impossible to track the respondents at any time during the data 

collection year. Some RECS data existed on each selected RTECS household; 

therefore, missing RTECS data were estimated by item imputation methods rather 

than by adjusting the weights for nonresponse.

Imputation Procedures

The most commonly used method of imputation for the RTECS was the "hot deck" 

procedure. This procedure requires sorting the file of households by variables 

related to the missing item. A household is then selected that has the same 

value for the related variables, and this "donor" household supplies the value 

of the variable that is missing in the "donee" household. Other imputation 

methods included regression estimates and the use of medium values. These 

procedures are described in more detail in the remainder of this section.

Household Vehicle Inventory

In some households, vehicles were acquired and/or disposed of during the survey 

year, causing the vehicle stock associated with those households to fluctuate. 

Efforts were made to contact households periodically throughout the survey year

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
to record changes in vehicle stock. Nevertheless, 1,654 households (41.1 

percent) could not be followed for a complete survey year. Hence, for that part 

of the year that a household was not "tracked," no record of possible vehicle 

acquisition or deposition was available.

For households with incomplete vehicle data, change or lack of change in vehicle 

stock was imputed by means of the "hot-deck" imputation method. In this pro 

cedure, donor and recipient households were matched according to variables such 

as income, number of vehicles, ages of vehicles, geographic area, known patterns 

of vehicle acquisition/disposition, and so on. The donor household record was 

inspected for that part of the survey year for which recipient household infor 

mation was lacking, and any vehicle acquisition/deposition or "no-change" was 

imputed to the recipient. Thus 375 (4.4 percent) of the 8,491 vehicles 

belonging to the sampled households during 1985 were imputed as being newly 

acquired vehicles. Vehicles "acquired" by hot-deck imputation also "acquired" 

from the donor's vehicle certain technical characteristics, such as: make, 

model, model year, transmission type, number of doors, fuel efficiency, and fuel 

type. Vehicle-use characteristics, such as air conditioning, number of drivers, 

and fuel cost, were imputed independently. Similarly, of the 8,491 sample 

vehicles, 300 (3.5 percent) were imputed as being disposed of.

Annual Mileage

Where possible, beginning- and end-of-year odometer readings were used to 

compute the miles driven (annual mileage) for a vehicle. In addition, the 

midyear update mailings and monthly fuel purchase logs provided intermediate 

odometer readings, as well as readings for acquired or disposed of vehicles. 

However, not all respondents provided the data; only part of the annual mileage 

was obtained for some vehicles and no mileage for others (Table Al).

For vehicles with 46 or more days of mileage data, the available mileage was 

scaled to the full year by use of an empirical distribution of monthly mileage 

percentages. Annual mileage data was imputed for the 4,054 vehicles (47.7 

percent) with 45 days or less of annual mileage data available. When 22 to 45 

days of mileage data were known, linear regression on this mileage data was used 

to impute for annual mileage. Where no mileage data were available, annual 

mileage was imputed by regressing on the respondent's estimate of mileage for 

the 12 months prior to the RECS survey, when this information was available. If 

this previous year's estimate was not available, the total number of miles 

traveled in 1985 was generally imputed using multiple regression on such 

variables as number of drivers, 1985 income, age of household head, type of 

vehicle, and use of vehicle on the job. This regression was also used for 

imputation of mileage to vehicles which were imputed as being acquired.

As a final step, the imputed annual mileage was adjusted to represent only that 

part of the year that the vehicle was in use by the household (to account for 

acquisition or disposal).

Miles per Gallon (MPG)

Each household in the RTECS sample was assigned 1 month in the survey year to 

record fuel purchases in logs for each vehicle. Monthly fuel purchase data were 

available and were of acceptable quality to allow the computation of MPG for 

3,412 vehicles (40.2 percent). Monthly MPG's for these vehicles were converted 

to "annualized" MPG's, based on the observed way that MPG varies for different 

months of the year. These conversions were performed within categories defined 

by vehicle type, make, model, and model year. Annualized MPG data together with 

annual mileage were used to estimate the number of gallons consumed per year by 

each vehicle; this in turn was used to compute annual fuel expenditures.

Fuel purchase logs were missing or inadequate for calculating annualized MPG's 

for 5,079 vehicles (59.8 percent). These MPG's were imputed by using the 

medians of the applicable categories defined above, plus a random error.

Vehicle Characteristics

The "hot-deck" method was used to impute for missing vehicle characteristics 

(Table A2). All imputations were performed within categories defined by other 

vehicle characteristics such as vehicle type, make, model, and model year. 

Additional characteristics that were sometimes used to define categories were 

employment status, number of drivers, and climate zone. The total number of 

vehicles is 8,491; the number and percentage of sample vehicles receiving 

imputed vehicle characteristics are indicated in Table A2.

Fuel Type

One of four fuel types (regular unleaded, regular leaded, premium, and 

diesel/gasohol/propane) was assigned to a vehicle if it represented more than 

half of the fuel purchased according to the monthly log. When missing or 

unusable, fuel type information was imputed by the hot-deck method within 

categories defined by vehicle type, make, and model year. Fuel type was imputed 

for 4,677 vehicles (55.1 percent).

Cost per Gallon

Because fuel prices vary throughout the year, the cost per gallon reported on 

the monthly fuel purchase log for each vehicle was adjusted to derive a more 

meaningful "annualized" price. Price adjustment ratios were produced for cells 

defined by Census region and fuel type, based upon the Average Pump Price Series 

of the Bureau of Labor Statistics' (BLS) Consumer Price Index. The total annual 

fuel expenditure for each vehicle was obtained as the product of gallons 

consumed and cost per gallon.

For the 4,601 vehicles (54.2 percent) where fuel price was missing, an 

imputation procedure was employed. Vehicles with nonmissing fuel price data 

were grouped by Census region, metropolitan/nonmetropolitan status, and fuel 

type. Annualized prices were averaged within each group, and the averages 

were used to supply the missing prices for recipient vehicles in the same 

group.

Quality of the Data
Quality of the Data

Introduction

Data from the 1985 RTECS are subject to many sources of sampling error, 

nonsampling error, and bias. Sampling error is a measure of the data vari 

ability that results from surveying a sample rather than the entire population. 

The different samples that could be selected would each produce different values 

for the survey statistics.

Nonsampling errors are measures of variability due to the conduct of the survey. 

Procedures to minimize these errors were discussed in Appendix A, "How the 

Survey Was Conducted." A major source of these errors is nonresponse bias. The 

imputation procedures used to minimize this bias were also discussed in Appendix 

A. The use of imputation procedures, however, can result in biased estimates of 

sampling errors, and thus can adversely affect data quality.

This Appendix discusses the development of sampling error estimates and 

procedures used to minimize the biasing effects of imputations on these 

estimates. A section on data quality compares the 1980 and 1983 RTECS results 

with other available data, and provides an analysis of the 1983 RTECS response 

rates. The tables of relative standard errors included at the end of this 

Appendix correspond to each of the tables in the Detailed Statistics section. 

That is, the statistics in the cells of Table Bl are the relative standard 

errors of the corresponding data in Table 1. The same applies to Tables B2 

and 2, B3 and 3, etc.

Sampling Error

The 1985 RTECS is based on a sample rather than a total census, and is thus 

subject to sampling error. Because probability sampling was used for RTECS, it 

is possible to estimate the size of the sampling error for any survey statistic. 

The measurement of the sampling error that is presented in Tables Bl through B13 

is the relative standard error (RSE). For a given survey statistic, Y, the 

relative standard error, RSE (Y), is given by

RSE (Y) = (Sy/Y) x 100.

The standard error of Y is S , and can be computed using Tables Bl through B13 

and the formula

S = RSE (Y) x Y/100.

The complex multistage, multiframe design of the survey made it virtually 

impossible to construct an exact algebraic estimate of the standard error of the 

survey statistics. The method used to estimate a standard error for each table 

cell statistic was "balanced half-sample replication" (see references 2 and 3). 

This method involved collapsing similar sampling strata so that primary sampling 

units (PSU's) became paired. Differences between the PSU's of each pair can be 

used in various ways to build an estimate of standard error. Balanced 

half-sample replication refers to the particular technique by which PSU's were 

repeatedly drawn from the collapsed strata during the calculations. Once the 

standard errors were computed, they were converted to RSE's because it is useful 

to express the size of a standard error as a percent of the survey statistic in 

question.

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
The confidence interval, another useful expression of sampling error, is an 

estimated range of values with a given probability of containing the true but 

unknown population value. In any normal distribution of sample statistics, 

the probability is 0.95 that an interval defined by the sample mean plus and 

minus 1.96 standard errors will contain the true population value. For 

example, Table 1 shows that an estimated total of 1,353 billion miles were 

driven by residential vehicles in the United States during 1985. Table Bl 

shows an RSE of 1.5 percent for this statistic. The standard error is

(1.5 x 1,353)/100 = 20.3.

The 95 percent confidence interval equals 1.96 times the standard error, or

1.96 x 20.3 = 40.

Therefore, the 95 percent confidence interval would be expressed as 1,353 (±40) 

billion miles. That is, one can be 95 percent confident that between 1,313 and 

1,393 billion miles were driven by the population in 1985.

Effects of Item Imputations on Sampling Errors

If missing data were not compensated for by imputation, survey statistics would 

generally be biased. For example, total annual mileage would be underestimated 

if the survey statistic were based only on the 54.6 percent of vehicles that had 

some mileage data available. Missing data were imputed to minimize the 

nonresponse bias in the survey statistics.

However, imputed data can result in biased estimates of the standard errors of 

survey statistics. Ideally, imputation procedures would provide the same data 

values that would have been obtained directly from the respondents, and 

imputations would not introduce bias into the standard error estimates. 

However, because imputations never have perfect accuracy, they can introduce a 

bias into the standard error estimates. This bias may result if standard 

error estimates fail to include a component of error due to the imputation 

itself, or if the imputation artificially reduces the variability naturally 

found among sample units. The size of this bias depends on the accuracy and 

type of imputation.

Hot-deck and regression procedures are the two major types of imputation used in 

RTECS (See Glossary). The accuracy of the hot-deck procedure depends on the 

homogeneity among donors and recipients within the imputation categories. 

Homogeneity can be increased by employing as many characteristics as possible 

to differentiate the imputation categories. However, finely differentiated 

categories may be impractical because of lack of sample data to fill the 

categories. A compromise is usually reached between limited sample size and 

the desire for finely differentiated categories which are internally 

homogeneous. Even so, hot-deck imputation may not seriously bias the standard 

error because this procedure selects donors at random from the distribution 

within each imputation category, and thus incorporates or "mimics" the 

variability already present among the respondents.

RTECS: Consumption Patterns of Household Vehicles 1985 

' Energy Information Administration
Imputed values that are predictions from regression equations may not seriously 

affect estimates O of standard error when those predictions are highly accurate 

(that is, with R^ close to 100 percent). However, regression imputations based 

on a model of less than near-perfect fit can result in underestimates of 

standard error, since such a model may not adequately account for the 

variability present among the sample units. A common technique to compensate 

for this bias is to add to each predicted value a random deviate from the 

distribution of residuals about the regression line.

In RTECS, regression equations were used to impute for the number of miles 

driven in 1985 for most of the 45.4 percent of vehicles with no mileage data 

available. The R for these fits ranged from 27.7 to 51.2 percent. Because 

no random residuals were applied to the predictions, these imputations could 

lead to underestimates of standard error. Furthermore, due to data limitations, 

the regression models were not fit independently within PSU's paired for 

standard error estimation by balanced repeated replications. The models were 

fit using any applicable data from the survey across all sampled households and 

vehicles. That is, the regression procedures "crossed" the boundaries between 

respective pair-members. Thus, regression-imputed mileage introduced an 

artificial homogeneity between the data of paired PSU's, contributing to the 

underestimation of standard error. The survey statistics affected would be 

total miles traveled, fuel consumption, and fuel expenditures. Data for these 

three statistics were excluded from standard error calculations for any vehicle 

for which mileage was imputed by regression. The purpose was to minimize the 

biasing effects of imputations on the RSE's in Tables Bl through B13.

Special Data Quality Studies

Comparisons with Other Data

Prior to conducting the 1985 RTECS, the results of previous RTECS were compared 

to other available data. No comparison has yet been made using the 1985 RTECS 

results. However, as all RTECS used the same survey methodology, there is no 

reason to believe that the results would be substantially different.

RTECS estimates of fuel efficiency (in miles per gallon) for 1980 and 1983 were 

compared with estimates from several other major sources. Generally, the 

results from other sources were consistent with estimates from RTECS. Where 

data yielded different estimates, differences existed in one or more of the 

following: the target population, sample selection methodology, definitions 

of vehicle categories, basic study objectives, and data collection methods.

The RTECS data were compared with the following data:

o Environmental Protection Agency (EPA) estimates of new car fuel 

economy

Based on the report "Analysis of In-Use Fuel Economy Estimates from the 

Residential Transportation Energy Consumption Survey and Other Data Sources,' 

1986, prepared by SRA Technologies, Inc. under contract with the EnergyInformation Administration.

RTECS: Consumption Patterns of Household Vehicles 1985 -,„ 

Energy Information Administration
o National Panel Diary (NPD), Inc. data on MPG estimates

o Published reports from the Department of Energy's Division of

Conservation and Renewable Energy based on NPD data as prepared by 

Energy and Environmental Analysis (EEA), Inc.

o Federal Highway Administration (FHWA) data from Highway Statistics

o Fleet mix data compiled by R.L. Polk from State vehicle registration 

data.

The EPA fuel efficiency esimates were derived by testing new cars, with a 

statistical adjustment for anticipated rates of highway and city driving. The 

RTECS estimates came from national samples of households that were asked to 

keep a log of fuel purchases.

NPD estimates were derived from information in ongoing diaries of fuel purchases 

and mileage. (The 1981 NPD survey was the primary source of data analyzed by 

EEA.) NPD Research, Inc. conducts market research on fuel purchasing patterns 

and vehicle use trends for the automotive and the petroleum marketing 

industries. It utilizes a national quota sample of 4,100 households, balanced 

according to demographic and geographic characteristics. The NPD records 

national and regional vehicle use and fuel purchase patterns over extended time 

periods. However, scientific or probability sampling is not employed. The 

participants in the survey do not represent a random sample of U.S. households.

The FHWA estimates of fuel efficiency (miles per gallon) were derived from 

aggregate data on registered vehicles, gasoline sales, and estimates of mileage. 

FHWA estimates include commercially operated vehicles, and FHWA uses a vehicle 

classification different from RTECS. RTECS data were reclassified when being 

compared with FHWA automobile data. FHWA includes passenger vans and jeep-like 

vehicles with automobiles. RTECS truck data could not be made comparable with 

FHWA truck data. Polk registration data for automobiles were used to study the 

RTECS fleet age distribution. Again, only automobiles were at all comparable 

between these sources.

RTECS and FHWA provide lower estimates of automobile MFC than does NPD. In 

1983, the estimated overall fuel economy of automobiles was 16.0 MPG in RTECS, 

and 18.4 in NPD. When vehicles were reclassified (passenger vans and jeep-like 

vehicles included with automobiles), the estimated fuel economy of automobiles 

was 15.7 MPG in RTECS and 16.7 MPG in FHWA. Estimates of fuel economy for light 

trucks in 1983 were 12.5 MPG in RTECS, compared with 14.5 in estimates provided 

by NPD. The fleet of vehicles sampled for NPD contained a higher proportion of 

newer vehicles than the fleet of vehicles sampled for RTECS. The fleet age 

distribution of E.TECS more closely approximated the national estimates of fleet 

age distribution derived from automobile registration data compiled by R.L. 

Polk, Inc. than those of the NPD. When comparisons are made by model year, 

RTECS ratings are somewhat lower than EPA new car ratings, while NPD ratings are 

often somewhat higher. It is important to note that both the RTECS and NPD MFC 

ratings are based on actual in-use conditions. The NPD ratings are based on 

consumer logs that cover several months, while the RTECS ratings are based on 

logs that cover only one month. Thus, the NPD data for individual vehicles have

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
smaller measurement errors than do RTECS data. However, as noted before, the 

NPD sample is not a random sample; therefore, the model year MPG rating for NPD 

may be biased.

Analysis of RTECS Response Rates

Appendix A presented the percentage of vehicles for which the main data items 

collected in the 1985 RECS were imputed. For data measuring annual mileage, 

47.7 percent of vehicles had imputed data, and for data measuring miles per 

gallon, 59.8 percent. In 1983, the values were 40.1 percent and 54 percent, 

respectively.

The above rates are the percentage of vehicles requiring imputation on a data 

item by item basis. In the R.TECS, households were required to provide these 

data items for each vehicle within the household. A study was made of response 

rates at the household level in contrast to the vehicle level on an item-by-item 

basis. For the 1983 RTECS data, response rates were analyzed at the household 

level, and a household response level percentage was computed for the two main 

RTECS data items collected—annual mileage and miles per gallon. A response 

level of 100 percent indicated that the household had provided information on 

annual mileage and miles per gallon for all vehicles within the household. A 

response level of 50 percent indicated that a household either (1) provided 50 

percent of the requested information for all vehicles, or (2) provided all of 

the requested information for only half of the vehicles. The frequency 

distribution of the 1983 household response levels is shown below:

Household Response Level Frequency in 1983 

(Percent) (Percent)

61 - 70 4.6

71 - 80 10.6

81-90 6.8

91 - 99 4.1

100 27.6

The two largest categories of response level were zero and 100 percent, each 

representing about one-fourth of the households; most of the remaining 

households were distributed in the categories above the 40 percent response 

level. Almost half of the households (48.9 percent) had a household response 

level of 71 percent or greater.

Consumption: See Fuel Consumption.

Cooling Degree-Days(CDD): A quantity used to estimate the need for cooling 

systems in buildings. Normally, cooling is not required in a building when 

the outdoor average daily temperature is below 65 degrees. (The average daily 

temperature is the mean of the maximum and minimum temperatures for a 24-hour 

period. ) Cooling degree-days are determined by subtracting 65 from the 

average daily temperature. For example, a day with an average temperature of 

85 degrees has 20 cooling degree-days (85 - 65 = 20), while a day with an 

average temperature of 65 degrees or lower has none. After being calculated 

for each day, the number of cooling degree-days can be summed over a larger 

unit of time (a month, a year),

Cooling degree-days for RTECS households in the 48 contiguous States and the 

District of Columbia were assigned according to the NOAA division in which 

each household was located. For Alaskan and Hawaiian households, cooling 

degree-days were assigned by appropriate nearby weather stations. See NOAA 

Division and Weather Zone.

RTECS: Consumption Patterns of Household Vehicles 1985

Cylinders; The number of cylinders in the vehicle engine. In a reciprocating 

engine, a cylinder is the chamber in which combustion occurs and the piston 

moves.

Drivers: Household members who drove a given vehicle on a regular basis at the 

time of the household interview.

Electricity: See Main Heating Fuel.

Energy Used in the Home: For electricity or natural gas, the quantity used by 

the household during the 365-day period. For fuel oil, kerosene, and 

liquefied petroleum gas (LPG), the quantity of fuel purchased, not fuel 

consumed. If the level of fuel in the storage tank was the same at the 

beginning and end of the annual period, then the quantity consumed would be 

the same as the quantity purchased. The level of fuel in the storage tank was 

not included in the data collection. The time period for household energy 

consumption for energy used in the home is April 1984 through March 1985.

Expenditures for Energy Used in the Home: For electricity and natural gas, 

the cost of electricity or natural gas consumed during the 365-day period. 

For households on a budget plan, the expenditures are for actual consumption. 

Fuel oil, kerosene, and LPG expenditures are for the amount of fuel purchased, 

which may differ from the amount of fuel consumed. For households that do not 

pay directly to their fuel supplier, the expenditures for fuels are estimated 

and included in the tables. Expenditures include State and local taxes, but 

exclude merchandise, repairs, or special service charges. The time period for 

expenditures for energy used in the home is April 1984 through March 1985.

Family Income: The total combined income in 1985 of all members of the family 

from all sources before taxes and deductions. It includes wages, salaries, 

tips, commissions, and income from Social Security, pensions, interest, 

dividends, rent, public assistance, and unemployment insurance. This includes 

the total income for all family members who lived in the household in 1985. 

Income of nonfamily members of the household is not included. "Family" 

includes the following types of relationships: mother, father, sister, 

brother, son, daughter, father-in-law, uncle, aunt, niece, grandchild, foster 

child, and similar relationships.

Fuel Consumption: The quantity of fuel used by vehicles during a 365-day 

period. See Appendix A for explanation of procedures used to convert the 

monthly fuel purchase log data to annualized motor fuel consumption.

Fuel Efficiency: See Miles per Gallon.

Fuel Expenditures: The cost, including taxes, of the gasoline, gasohol or 

diesel fuel added to the vehicle's tank. Expenditures do not include the cost 

of oil or other items that may have been purchased at the same time as the 

fuel.

Fuel Oil: See Main Heating Fuel.

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
Fuel Type: The predominant type of fuel purchased and reported during the 

period in which the respondent was completing a fuel purchase log. Data 

categories are leaded and unleaded gasoline, and "other" which includes diesel 

motor fuel, propane, and gasohol. See Gasoline, Gasohol, Unleaded Gasoline 

and Leaded Gasoline.

Gallons Consumed; The estimated number of gallons of fuel used during the year, 

based upon miles-per-gallon data derived from a 1-month fuel purchase log and 

odometer readings for the beginning of the year and the end of the year.

Gasohol: A blend of finished motor gasoline (leaded or unleaded) and alcohol 

(generally ethanol but sometimes methanol), limited to 10 percent alcohol by 

volume. See Gasoline.

Gasoline: A complex mixture of relatively volatile hydrocarbons, with or 

without small quantities of additives, blended to form a fuel suitable for use 

in spark-ignition engines. Motor gasoline includes leaded gasoline and 

unleaded gasoline. See Leaded Gasoline and Unleaded Gasoline.

HDD: See Heating Degree-Days.

Head of Household: See Householder.

Heating Degree-Days(HDD); A quantity used to estimate the need for heating 

systems in buildings. Normally, heating is not required in a building when 

the outdoor average daily temperature is above 65 degrees. (The average daily 

temperature is the mean of the maximum and minimum temperature for a 24-hour 

period.) Heating degree-days are determined by subtracting the average daily 

temperature below 65 degrees from the base 65. For example, a day with an 

average temperature of 50 degrees has 15 heating degree-days (65 - 50 = 15), 

while one with an average temperature of 65 or higher has none.

The heating degree-days for RTECS households in the 48 contiguous States and the 

District of Columbia were assigned according to the NOAA division in 

which each household is located. Heating degree-days for Alaskan and Hawaiian 

households were assigned by appropriate nearby weather stations. See NOAA 

Division and Weather Zone.

Hispanic Descent; A householder of either Spanish or Portuguese origin or 

ancestry. See Origin.

Hot-Deck Imputation: A statistical procedure for deriving a probable response 

to a questionnaire item concerning a household or vehicle, where no response 

was given during the survey. To perform the procedure, an analyst sorts the 

households or vehicles by variables related to the missing item. Thus, a 

series of sort categories are formed, which are internally homogeneous with 

respect to the sort variables. Within each category, households or vehicles 

for which the questionnaire item is not missing are randomly selected to serve 

as "donors" to supply values for the missing item of "recipient" households or 

vehicles. See Appendix A for more details. See Imputation.

RTECS: Consumption Patterns of Household Vehicles 1985 

166 Energy Information Administration
Household: A family, an individual, or a group of up to nine unrelated 

persons occupying the same housing unit. "Occupy" means the housing unit was 

the person's usual or permanent place of residence at the time of the first 

field contact. The household includes babies, lodgers, boarders, employed 

persons who live in the housing unit, and persons who usually live in the 

household but are away traveling or in a hospital. The household does not 

include persons who are normally members of the household but who were away 

from home as college students or members of the armed forces at the time of 

the contact. The household does not include persons temporarily visiting with 

the household if they have a place of residence elsewhere, persons who take their 

meals with the household but usually lodge or sleep elsewhere, domestic employees 

or other persons employed by the household who do not sleep in the same housing 

unit, or persons who are former members of the household, but have since become 

inmates of correction or penal institutions, mental institutions, homes for the 

aged or needy, homes or hospitals for the chronically ill or handicapped, nursing 

homes, convents or monasteries, or other places in which residents may remain for 

long periods of time. By definition, the number of households is the same as the 

number of occupied housing units.

Householder: The head of household or the person (or one of the persons) in 

whose name the home is owned or rented. If there is no lease or similar 

agreement, or if the person who owns the home or pays the rent does not live 

in the housing unit, the householder is the person responsible for paying the 

household bills or generally in charge.

Housing Unit: A structure or part of a structure where a household lives. It 

has direct access from the outside of the building or through a common hall. 

Housing units do not include group quarters such as prisons or nursing homes.

Imputation: A group of statistical techniques for estimating probable 

responses to questionnaire items concerning households or vehicles, where no 

responses or poor quality responses were given during the survey. The two 

most common techniques employed in this survey were "hot-deck" and 

"regression." See Appendix A for more details. See also Hot-Deck Imputation 

and Regression Imputation.

Jeep-like Vehicles: Include light trucks which are similar to jeeps. Other 

common terms for these vehicles are special purpose, utility or off-the-road 

vehicles. They may have 4-or-2 wheel drive.

Kerosene: See Main Heating Fuel.

Leaded Gasoline: Contains more than 0.05 gram of lead per gallon or more than 

0.005 gram of phosphorus per gallon. Premium and regular grades are included. 

See Gasoline and Unleaded Gasoline.

Liquefied Petroleum Gas or LPG; See Main Heating Fuel.

RTECS: Consumption Patterns of Household Vehicles 1985 , ,., 

Energy Information Administration
Main Heating Fuel; The primary fuel delivered to a residential site. It may 

be converted to some other form of energy at the site. In this report, 

electricity is included. The following are defined as primary fuels for this 

report:

Electricity: metered electric power supplied by a central utility 

company to a residence via underground or above-ground power lines. It 

does not refer to electricity generated on site for the exclusive use of 

a residence. When a residence has its own generating capability, the 

fuel used for the generator will be specified. The Btu equivalent for 

electricity is the energy value of electricity as received by the 

household (3,412 Btu per kilowatthour). For this report, energy losses 

that occur in generating and transmitting electricity are not included in 

the conversion of electricity into Btu. If these losses were to be 

included, the conversion rate would generally be about 10,353 Btu per 

kilowatthour.

Fuel oil: No. 1, No. 2, or No. 4 grade fuel oil or residual oil that is 

burned for space- or water-heating purposes. No. I distillate fuel oil is a 

form of heating oil used mostly as a blending stock to assure that heavier 

grades of fuel flow under severe cold weather conditions. No. 2 distillate 

refers to both No. 2 heating oil and No. 2 diesel fuel. Although these 

products are not identical, they are essentially interchangeable for most 

applications. No. 2 fuel oil is the most common form of heating oil. No. 4 

distillate is a blend of No. 2 and No. 5 or No. 6 residual fuel oil, used in 

large stationary diesel engines and boilers equipped with fuel preheating 

equipment. Residual fuel oil refers to the heavier oils that remain after 

the distillate fuel oils and lighter hydrocarbons are boiled off in refinery 

operations.

Kerosene: the generic name for a distilled product of oil or coal, 

having properties similar to those of No. 1 fuel oil. Kerosene is used 

for cooking stoves, for space heating or water heating, or for lighting 

equipment that uses wicks. It is sometimes sold under the names "range 

oil," "stove oil," or "coal oil."

LPG or liquefied petroleum gas: any fuel gas supplied to a residence in 

liquid form, such as propane or butane. It is usually delivered by tank 

truck and stored near the residence in a tank or cylinder until used. 

Propane was the most common liquefied petroleum gas supplied to REGS 

households. Household use of LPG solely for outdoor gas grills is not 

considered sufficient use to mark the household as a user of LPG.

Natural gas: utility gas supplied by underground pipeline to individual 

housing units by a central utility company. It does not refer to 

privately owned gas wells operated by the household, nor to LPG.

Measured Heated Area of Residence: The floor area of the housing unit that is 

enclosed from the weather. Basements are included whether or not they contain 

finished space. Garages are included if they have a wall in common with the 

house. Attics that have finished space and attics that have some heated space

RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
are included. Crawl spaces are not included even if they are enclosed from 

the weather. Sheds and other buildings that are not attached to the house are 

not included. "Measured" area means that the measurement of the dimensions of 

the home did not rely on the respondent's reports but was an actual 

measurement by the interviewer using a metallic, retractable, 50-foot tape 

measure. "Heated area" is that portion of the measured area that is heated 

during most of the season. Rooms that are shut off during the heating season 

to save on fuel use are not counted as heated area. Attached garages that are 

unheated and unheated areas in basements and attics are not counted as heated 

area.

Metropolitan; A group of households located within Metropolitan Statistical 

Areas (MSA's) as defined in the 1980 Census. Except in New England, an MSA is 

a county or group of contiguous counties that contain at least one city of 

50,000 inhabitants or more, or "twin cities" with a combined population of at 

least 50,000. The contiguous counties are included in an MSA if, according to 

certain criteria, they are essentially metropolitan in character and are 

socially and economically integrated with the central city. In New England, 

MSA's consist of towns and cities, rather than counties. See Nonmetropolitan.

Metropolitan Status: Refers to geographic location of the households in 

relationship to Metropolitan Statistical Areas (MSA's). See Metropolitan and 

Nonmetropolitan.

Miles Driven: The total number of miles driven during 1985.

Miles per Gallon or MPG: A measure of vehicle efficiency. Miles per gallon or 

MFC as presented in this report represents "Fleet Miles per Gallon." For each 

subgroup or "table cell," MPG is computed as the ratio of the total number of 

miles traveled to the total number of gallons consumed. The MPG value reported 

for a given vehicle on a monthly fuel purchase log was used with annual odometer 

readings to compute the total number of gallons consumed annually for that 

vehicle. See Appendix A for more details.

Model Year: The year in which the particular style or design of vehicle was 

introduced or manufactured.

Motor Fuel Consumption: See Fuel Consumption.

Motor Fuel: See Fuel Type.

Motor Fuel Expenditures: See Fuel Expenditures.

MPG: See Miles per Gallon.

MSA; See Metropolitan.

Natural Gas; See Main Heating Fuel.

NOAA Division: One of the 344 weather divisions designated by the National 

Oceanic and Atmospheric Administration (NOAA) encompassing the 48 contiguous 

States. These divisions usually follow county borders to encompass counties

RTECS: Consumption Patterns of Household Vehicles 1985

Energy Information Administration 169
with similar weather conditions. The NOAA division does not follow county 

borders when weather conditions vary considerably within a county such as is 

likely to happen when the county borders the ocean or contains high mountains. 

A State contains an average of seven NOAA divisions; a NOAA division contains 

an average of nine counties.

Nonmetropolitan: Households not located within Metropolitan Statistical 

Areas as defined in the 1980 Census. See Metropolitan.

Origin: The primary ethnic background of the person considered to be the 

householder. Each respondent was asked, "Which of the groups on this exhibit 

best describes the householder?" The groups included: white, black or Negro, 

American Indian, Alaskan native, Asian, and Pacific Islander. The word "race" 

was not used in either the questionnaire or the instructions.

Pickup Truck: Includes compact and full size pickup trucks.

Poverty; Low-income classifications to which certain households are assigned. 

"Below^lOO percent of poverty" encompasses a group of households with incomes 

below the poverty level as defined by the U.S. Bureau of the Census. "Below 

125 percent of poverty" includes a group of households with incomes below 125 

percent of the poverty level; this represents an alternative level for defining 

poverty. The definitions of "poverty" are based on the number of family members 

in the household and the income of the entire family. The income levels used to 

define poverty in this report are shown below.

a The income category that contained the Census threshold was taken as the upper limit in defining poverty when the Census threshold was equal to or 

above the midpoint of the income category For example, since the threshold of 55,400 was not above the midpoint of the category 55,000 to 55.999, the 

next lower income category was used.

b Figures from the US. Bureau of the Census, Money Income and Poverty Status of Families and Persons in the United States: T984 (Advance Data 

from the March 1985 Current Population Survey) (Current Population Reports. Series P-60, No. 149, August 1985), Table A1, p. 31.

Source: Energy Information Administration, Office of Energy Markets and End Use. The 1984 Residential Energy Consumption Survey.

Because RECS and RTECS income data were collected by using categories of income 

(for example, $3,000 to $3,999), Census thresholds for poverty could not be 

exactly matched. Furthermore, underreporting of income is a problem in surveys

170 RTECS: Consumption Patterns of Household Vehicles 1985 

Energy Information Administration
of this type. Respondents may forget to mention some types of income or report 

them as less than they are. Underreporting may be a greater problem in the REGS 

and RTECS, which measures income by one question, than in the Current Population 

Survey (CPS), which asks questions regarding each source of income for each 

household member. For example, whereas for 1984 the RECS estimate for households 

below 100 percent of poverty was 13.680 million, the CPS estimate for the same 

year was 13.886 million.

Primary Sampling Unit (PSU): A sampling unit selected at the first stage in 

multistage area probability sampling. A PSU typically consists of one to 

several contiguous counties—for example, a metropolitan area with surrounding 

suburban counties. The approximately 3,100 counties and independent cities of 

the contiguous United States were grouped into about 1,800 PSU's by a 

procedure similar to the one used by the Census Bureau for its Current 

Population Survey. PSU's can be composed of one or more MSA's or can be 

composed of rural counties. See Metropolitan and Appendix A.

Quadrillion: The number 1,000,000,000,000,000 or 10 15 . 

Race: See Origin.

Regression Imputation: A statistical procedure that was used to estimate 

annual mileage for vehicles where little or no mileage data were available. 

The procedure involved the least-squares derivation of mathematical equations 

that expressed mileage as a function of such variables as number of drivers, 

household income, age of household head, and others. See Appendix B for more 

details. See Imputation and Hot-Deck Imputation.

Residential; Refers to occupied housing units, including mobile homes, 

single-family housing units (attached and detached), and apartments. The 

definition of housing units is the same as that used by the U.S. Bureau of the 

Census. See Household.

Residential Energy Expenditures: See Expenditures for Energy Used in the 

Home.

Transmission Type: The householder was asked if each vehicle had an automatic 

or manual shift transmission. The transmission is the part of a vehicle that 

transmits motive force from the engine to the wheels, usually by means of 

gears and either a hydraulic "torque-converter" (automatic) or clutch assembly 

(manual).

Transportation Energy Expenditures: See Fuel Expenditures.

Unleaded Gasoline: Contains not more than 0.05 gram of lead per gallon and 

not more than 0.005 gram of phosphorus per gallon. Premium and regular grades 

are included, depending on the octane rating. See Gasoline and Leaded 

Gasoline.

Vehicle Used on the Job: Refers to a vehicle used by anyone in the household 

for job-related activities, excluding commuting to and from work.

RTECS: Consumption Patterns of Household Vehicles 1985

Energy Information Administration 1' 1
Vehicles: Motorized vehicles used by U.S. households for personal trans 

portation. Excluded are: motorcycles, mopeds, large trucks, and buses. 

Included are: automobiles, station wagons, passenger vans, cargo vans, motor 

homes, pickup trucks, and jeeps or similar vehicles. In order to be included, 

vehicles must be: (1) owned by members of the household, or (2) company cars 

not owned by household members but regularly available to household members 

for their personal use and ordinarily kept at home, or (3) rented or leased 

for 1 month or more. See Vehicle Used on the Job.

Weather Zone; One of seven distinct areas, designated by the American 

Institute of Architects (AIA) for the U.S. Department of Energy and the U.S. 

Department of Housing and Urban Development, that are used to classify housing 

units or buildings by long-term weather conditions. The zones are defined by 

the annual sums of heating degree-days (HDD) and cooling degree-days (CDD) 

averaged over 45 years, as follows:
