PREFACE

This is the fifth report of the Office of the Consumption 

Data System, Office of Program Development, Energy Information 

Administration, presenting final data from the National 

Interim Energy Consumption Survey (NIECS). The report 

contains data on general structural features of the housing 

unit, major appliances used by the household, heating equip 

ment, and fuels used for space heating, water heating, 

cooking, and demographic information about the households. 

These tables are from the data file that contains imputations 

for missing data and includes data from mailed questionnaires. 

This report supersedes the preliminary report except for 

users who may be interested in the extent of missing data 

that is presented in the preliminary report.

Included in the report is a summary of the findings, a 

description of how the survey was conducted, a copy of the 

questionnaire, generalized sampling errors, and a glossary 

of terms.

1. CHARACTERISTICS OF THE HOUSING STOCK AND 

HOUSEHOLDS: FINAL REPORT
General Housing Characteristics

This report consists of four sets of tables describing the 

households and the housing units which were selected for the 

National Interim Energy Consumption Survey (NIECS). The 

first set (Tables 1A through 4B) presents statistics con 

cerned with general structural features of the housing unit 

including: type, size, age, and value of the structure. 

Tables 5A through 6B show household inventories of major 

appliances. Displayed here are statistics on the number, 

type, and features of appliances used by the households. 

The third set (Tables 7A through 14B) deals with household 

heating equipment and the distribution of fuels used for 

space heating, water heating, and cooking. Tables ISA and 

15B give some general demographic information on the NIECS 

households.

Each table is presented in two ways. The "A" series tables 

are given in weighted counts of housing units rounded to the 

nearest thousand. Series "E" tables are given in weighted 

column percentages. Column percentages can only be used in 

making relative comparisons. Table IB shows that 47 percent 

of the units in the Northeast were built in 1939 or earlier 

as compared to 42 percent in the North Central region. 

However, Table 1A shows that there are over 500,000 more 

units in the North Central region which were built before 

1940. To make absolute comparisons, therefore, it is nec 

essary to use the "A" series of tables.

The sample base used for-the report is 4,081. This figure 

includes all occupied residential housing units sampled in 

the NIECS during the winter of 1978-1979. A series of 

weights was applied to the sample units to allow estimates 

to be made of the entire population. After weighting, the 

estimated population was equal to 76.6 million housing 

units. The 100 percent figure given in the upper left hand 

corner in the "B" series tables represents this weighted 

number. The results given in the preliminary version of this 

report^ are slightly different from those presented here. 

The sample base has been increased by 239 households because 

data were obtained from a final follow-up effort using mail 

questionnaires. In addition, data items which were missing 

in the preliminary report have been imputed (see the section 

on "How the Survey Was Conducted") and information from a 

survey of rental agents was used to improve reports of fuel 

used in apartment buildings.

Characteristics of the Housing Stock

The first set of tables presents general structural char 

acteristics of the housing stock for the surveyed housing 

units. The majority of the units were owner-occupied, 

detached single family houses.

A third of the housing units were built before 1940. A 

sizable minority of respondents 35 percent (+2.4) 2 were 

unable to estimate the size, in square feet, of their homes. 

Two-thirds (+2.8) of those who were able to estimate the 

size of their homes believed that their homes were smaller 

than 1,500 square feet.

Most housing units had only one floor (71 percent +2.2) and 

the median number of rooms per unit was five.

Over 40 percent (+2.4) had no air conditioning and in those 

units with air conditioning, window units were more prevalent 

than central systems.

level. For a discussion of sampling errors (and a table for 

their computation, see pages 56-58.

Comparisons on similar items were made between the NIECS 

data and findings reported in the 1976 Annual Housing Survey 

(AHS). The NIECS data showed a small but significant increase 

in the number of housing units having air conditioning. 

Other comparisons between similar items including ownership, 

the year the house was built, and the number of rooms, 

showed that no significant changes had taken place in the 

two years between the surveys.

Most of the households paid for all of the energy-related 

utilities used by the housing unit.

Characteristics of the Appliance Stock

The second set of tables (5 and 6) gives the type, number, and 

features of the major applicances used by the households. Vir 

tually all of the housing units had at least one refrigerator 

and one oven. Nearly three-fourths had a washing machine 

and over half had a clothes dryer. Freezers and dishwashers 

were found in slightly more than a third of the housing 

units.

Major Appliances

Refrigerator 100%

Oven 98%

Washing Machine 74%

Clothes Dryer 59% 

Separate Food Freezer 35%

Dishwasher 35%

Microwave Oven 8%

A comparison of Census figures from 1974 4 with NIECS findings 

revealed that ownership (or use in the home) of all the 

major appliances surveyed increased slightly from 1974 to 

1978.

However, with the exception of dishwashers, which were found 

in 35 percent (+_2.4) of the the housing units in 1978 as 

compared to 28.4 percent in 1974, the differences were not 

significant. Microwave ovens, which were found in 8 percent 

(+_1.3) of the NIECS households, were not included in the 

Census Bureau surveys.

The first part of Tables 5A and 5B shows the percentage 

distribution of housing units having at least one of each of 

seven major appliances; only one refrigerator, for example, 

per household was counted. The second section gives an 

inventory; that is, all the appliances in the housing unit 

were included. Although 10 percent (+1.4) of the housing 

units had seven or more appliances, this does not mean that 

these units had one each of the seven appliances listed. 

Some households had more than one oven or refrigerator and 

each was counted separately for the inventory.

Tables 6A and 6B give more detailed information on the 

types, numbers, and features of major household appliances. 

By far, the most popular refrigerator features were temper 

ature control 97 percent (+0.8), separate freezer door 

76 percent (+2.2), and full frost free 53 percent (+2.4). 

Households that used microwave ovens had conventional gas or 

electric ovens as well. Self-cleaning or continuous cleaning 

ovens were found in only a small portion of the housing 

units.

and Ownership", pp. 22-30.
Heating Equipment and Fuels

The third set of tables shows the types of heating equipment 

and fuels used in the residential sector. Tables 7A and 7B 

give a breakdown of primary and secondary heating equipment 

by primary heating fuel. In the majority of the surveyed 

housing units 55 percent (+2.4), natural gas was used to 

fuel the main heating equipment. Fuel oil or kerosene, at 

22 percent (+2.2), and electricity at 16 percent (+1.8), 

followed by natural gas.

Fuel Oil 16,919 22

Electricity 12,071 16

LPG 3,124 4

Wood 1,885 2

Other, none 764 1

Of those housing units having secondary heating equipment, nearly 

half 47 percent (+4.2) used wood for fuel.

Forced air systems were the most prevalent type of primary 

heating equipment 52 percent (+_2.4) . Hot water systems were 

used in 18 percent (+2.0) of the homes. Various kinds of equip 

ment used to heat individual rooms constituted the primary 

source of heat for 22 percent (+2.2) of the housing units.

Warm Air 39,548 " 52

Hot Water 13,487 18

Other, None 6,465 8

Tables 8A and 8B show the distribution of fuels used for space 

heating, water heating, and cooking. Nearly all of the sur 

veyed households used either electricity or natural gas for 

cooking and water heating. Electricity was used for water 

heating by 33 percent (+_2.4) and for cooking by 52 percent 

(+_2.4) of the households. Natural gas was used for water 

heating by 55 percent (+2.4) and for cooking by 40 percent 

(+_2.4). Approximately a third of the households 32 percent 

(+2.4) used natural gas for space heating, water heating, 

and cooking.

Tables 9A through 14B show primary heating equipment and 

primary heating fuel by: census region (and rural/urban), 

weather zones, type of housing structure, year house built, 

type and presence of air conditioning and family income.
Tables ISA and 15B present selected demographic data on the 

NIECS households. The typical NIECS household was composed 

of a married couple 67 percent (+2.4) with one of them being 

a full-time wage earner. The median and modal number of 

household members was two. Among unmarried respondents, 

twice as many households were headed by women 22 percent 

(+2.2). Poor households were more concentrated among blacks, 

the elderly, households headed by females, and those with 

grade school educations.

3. USE OF THE GENERALIZED VARIANCE TABLES

55
The following tables allow the user to estimate the standard 

error of estimates calculated on the National Interim Energy 

Consumption Survey (NIECS) data.

Standard Error of Estimated Percentages. (To be used with

the "B" series of tables.) The estimated standard error or

reliability of a percentage depends upon both the percentage

and the base upon which the percent was calculated.

In order to use Table A:

• Determine how many households in the sample belong 

to the base that are to be considered for the 

characteristic. (This will be illustrated in the 

second example.) The appropriate row in the table 

is now available.

• Using the table of estimates, determine what

percentage was estimated for this characteristic. 

The appropriate entry in the table is now located.

• Since these tables are based on one standard

deviation, a 95 percent confidence interval (two 

standard deviations) would equal twice the value 

in the table.

Table A. Standard Error of Percentages Table

__________________________(68 Chances out of 100)_______________________

Base of Percentage ____________Estimated Percentage________________________

(thousands)_________1 or 99 2 or 98 5 or 95 10 or 90 15 or 85 25 or 75 50

1,000 2.1 3.0 4.6 6.3 7.5 9.2 10.6

5,000 .9 1.3 2.1 2.8 3.4 4.1 4.7

25,000 .4 .6 .9 1.3 1.5 1.8 2.1

50,000 .3 .4 .7 .9 1.1 1.3 1.5

76,600 .2 .3 .5 .7 .9 1.1 1.2

56
Two examples follow:

Suppose that of the 76.6 million houses, 18 percent 

were built between 1950 and 1959. Using the Standard 

Error of Percentages Table (see Table A), the 76.6 row 

and 25 percent column yield a table value of 1.2 

(which is an overestimate since percent is less than 25) 

This means that 95 percent confidence interval is 15.8 

to 20.2 (18 + 2.0(1.1)).

Now, suppose that an estimate of the percent of 

houses built in the South between 1950 and 1959 is 

desired. The base is all households in the South, 

(24.6 million) and the estimated percentage is 

20 percent. The proper entry in the table is 1.8 

which belongs in the 25.0 million row and the 25 

percent column. Our 95 percent confidence interval 

now is 16.4 to 23.6 (20 + 2.0(1.8)).

•'-To obtain a more precise estimate of sampling error, 

interpolation of table values can be employed. The fol 

lowing method would be used to interpolate a value for 18 

percent on a base of 76.6 million which would be between , 

and 1.1.

(18-15) (1.1 - .9) + .9 = 1.0 

(25-15)

57
Standard Error of Estimated Counts. Linear interpolation 

should be used for counts not specifically shown in Table B, 

An example follows:

• If the estimated count is 48 million, then the

estimate of the standard error can be computed by 

linear interpolation as follows:

(48-45) (.90-.92) + .92 = .91

(50-45)

Standard Errors of Ratio. For ratios of the form (100) (x/y) 

where x is not a subclass of y, an approximation to the 

standard error of the ratio is given by:

100

x = the numerator of the ratio

y = the denominator of the ratio 

ox = the standard error of the numerator 

ay = the standard error of the denominator

Standard Errors of Differences. The standard error of a 

difference between estimates is approximately equal to the 

square root of the sum of the squares of the standard errors 

considered separately.

APPENDIX A. NATIONAL INTERIM ENERGY

CONSUMPTION SURVEY: 

HOW THE SURVEY WAS CONDUCTED

60
Introduction

The National Interim Energy Consumption Survey (NIECS)! was 

designed by the Energy Information Administration (EIA) to 

provide information related to energy consumption by the 

residential sector. 2 This survey, along with analogous 

studies for the commercial and industrial sectors, will 

enable the analysis of comprehensive consumption patterns 

for the United States.

Information on energy use in the residential sector was 

collected at the household level. A representative na 

tional sample of households was selected in the 48 con 

tiguous states plus the District of Columbia. The data on 

actual energy consumption was obtained from fuel records 

maintained by the household's fuel suppliers. An inventory 

of motor vehicles used by the household was also included in 

the survey.

Data Collection

Response Analysis Corporation (RAC), of Princeton, New 

Jersey, conducted the interviews. A total of 4,849 housing 

units were drawn in the original sample. Of these, 342 were 

ineligible for this survey because they were either vacant 

or seasonal units (the occupants did not live in them for 

more than half of the year). Of the 4,507 eligible units, 

interviews were obtained from 3,842 households, yielding an 

initial response rate of 85.2 percent. Subsequently, mail 

questionnaires (see Appendix C) were sent to the 665 house 

holds that were not interviewed. Completed mail question 

naires were received from 239 of the households. This 

additional effort increased the response rate by 5.3 percent.

Initial household contacts were begun in October 1978. The 

44-minute interview covered: structural features related to 

energy, such as size, insulation, and openings; the heating 

and cooling systems and the fuels used in these systems; 

energy conservation efforts; information on household appli 

ances and vehicles; and demographic data on household mem 

bers. At the conclusion of the interview, respondents were 

asked to sign waivers authorizing Response Analysis Corporation 

(RAC) to obtain their records of fuel consumption from their 

fuel supplier.

1-Not to be confused with NEIC—the National Energy Infor 

mation Center which is EIA's public information office. 

2Form Number EIA-84; OMB 38S-78028

SI
Most of the 327 interviewers employed by RAC had had pre 

vious survey experience. Training for NIECS was done by 

mail, using a 59-page instruction booklet. The booklet 

included specific procedures for conducting this survey and 

provided guidelines on how to handle various interpretations 

of questions. A practice interview and a quiz on the in 

structions were also parts of the training. An interviewer 

conducted about 12 interviews on the average. The most 

interviews conducted by a single interviewer was 47, while 

several interviewers completed as few as one. Twenty per 

cent of the interviews were verified to insure that inter 

views were conducted in person.

Sample Design

The NIECS sample is a representative area probability sample 

consisting of 103 primary sampling units (PSU's). These 

PSU's were selected from approximately 1,140 PSU's that col 

lectively form a mutually exclusive and exhaustive division 

of the contiguous United States. Each PSU is a well-defined 

geographic unit, usually consisting of one or more counties. 

Based on the 1970 Census, PSU sizes range from a population 

of 50,000 to approximately 3,300,000. Region, metropolitan 

status, and size classification were the primary considera 

tions in the selection of the sampled PSU's.

Within each PSU, secondary sampling units (SSU's) were 

defined. Based upon 1970 Census counts, 400 SSU's were 

selected from the 103 PSU's. Each of these SSU's contained 

approximately 2,500 persons and consisted of one or more 

blocks in urban areas and one or more enumeration districts 

in the nonurban areas. An additional 56 SSU's were selected 

independently. These 56 SSU's comprised probability selection 

of areas that had undergone substantial new construction 

since 1970. Independent sources (Reuben H. Donnelley address 

lists and county data) were used to update the population 

for these SSU's. This effort to locate areas of new con 

struction was undertaken to control the variation in cluster 

size.

Within each SSU, subdivisions were made. Census block 

statistics and rough field counts were used to break up each 

SSU into segments. Interviewers listed all housing units in 

the segment, completing this phase of the survey in the 

summer of 1978. The segments were formed so that they 

ultimately contained about 25 households. Finally, a sample 

of 10 or 11 households was selected to be visited. Thus, 

within each SSU 10 or 11 households were sampled, within 

each PSU an average of 40 to 45 households were sampled, and 

nationally, about 4,500 units were sampled.

62
Survey Estimates

Weights were calculated for each sample household to: 1) 

compensate for differences in probabilities of selection, 2) 

adjust for differences in interview completion rate in 

individual sampling locations, and 3) expand data for sample 

households to estimates for the total universe (all house 

holds in the contiguous 48 states plus the District of 

Columbia).

In order to increase the precision of our estimates, a 

technique called ratio estimation was employed. Ratio 

estimation uses known distributions of the population. 

These adjustments took place in two stages for the NIECS. 

The first stage factor was a ratio of the total number of 

households in each region by fuel type to an estimate of the 

number of households in each category. Only the PSU's in 

our sample and their appropriate weights were used. The 

figures used in both the numerator and denominator were 

based on the 1970 Census. The implementation of this factor 

reduced the amount of variance due to the sampling of PSU's. 

The second stage factor adjusted data from the survey to 

independently derived current estimates of the number of 

households for specified groups. The ratio adjustment was 

calculated for each region by type of community. The second 

stage factor reduced both the between PSU variance, as in 

the first stage, and the within PSU variance.

Estimation for Nonresponse

When data was unattainable from a nonresponding household, 

the weights from the households in the final cluster were 

increased to make-up for the nonresponding household.

Item nonresponse required a customized procedure for each 

data element. The data elements were divided into two 

categories: those with minimum nonresponse (about one 

percent), and those with more substantial nonresponse. The 

basic procedure attributed the most common response 

(modal value) to the first class of variables. In the 

second group where nonresponse was significant, a "hot deck" 

procedure was implemented. There were variations to this 

procedure depending on the importance of the data element, 

the interrelationship of data elements, and the consistency 

of data. Some elements such as amount of attic insulation 

were not imputed at all and a "don't know" response was 

accepted. Square footage and transportation data were not 

imputed.
Evaluation of Nonresponse

Basic information on all 4,507 households was obtained from 

the listing procedure. It was, therefore, possible to 

compare the responding households to the nonresponding 

households.

Table C gives a percentage breakdown of respondents and nonrespondents by structure type and SMSA classification.

Response rates in large urban areas (where apartment buildings 

with five or more units are more common) were somewhat lower 

than in other geographic locations.

Our nonrespondents were classified into eight sub-categories 

including "not-at-home," "refused," "illness," "language 

barrier," "interview of wrong household," "security building," 

"moved after initial contact," and "other." Of the 426 nonrespondents, 21 percent were not at home, 75 percent refused, 

and 4 percent were in the remaining categories.

Table D shows that the distribution of structure type for 

refusals was more similar to the respondents than the notat-home households. On the other hand, the geographic 

distribution indicated a somewhat different trend. Refusals 

and not-at-home households were distributed more like each 

other than to responding households.
Additional Survey Components

One purpose of the NIECS was to test the procedures and 

methodology for RECS. Three studies, in addition to the 

basic NIECS survey, are also being conducted. These studies 

will be used to determine what additions and modifications 

should be made for RECS.

When renters did not pay directly for their fuel costs, an 

interviewer contacted the apartment manager by telephone to 

ask what space and water heating fuels were used in the 

apartment building. These data have been incorporated into 

the NIECS data set, resulting in more accurate information 

about rental housing units.

A transportation panel consisting of a subset of the NIECS 

sample began in June 1979. Participating households are 

asked to keep a log of their fuel purchases and odometer 

readings for a two-month period. The panel consists of 500 

to 1,000 households reporting each month. Separate tabula 

tions of these data are planned.

Fifty NIECS households were selected to be part of an 

energy assessment study. Trained technicians analyzed the 

energy-related components of a house. Exact square footage, 

temperature distribution in various parts of the house, 

presence of insulation, and features of major appliances 

(including heating and cooling equipment) were surveyed. 

Detailed evaluations of this pretest are being developed.

Data From Non-household Sources (Fuel Suppliers)

Respondents in 95 percent of the interviewed households 

signed waivers to permit fuel suppliers to give Response 

Analysis Corporation the monthly record of their past year's 

fuel purchases. The data contained both the amount sold and 

the price of the fuel. The suppliers were contacted between 

March and May 1979 and were asked to supply fuel billing 

information for the previous 12-month period.

In order to attain the highest response rate possible, the 

following procedures were used:

• Letters were sent to each company after RAC

located the person who would act on the request 

for fuel bills. Follow up telephone calls were 

made to insure the receipt of the letter and to 

help with any problems that may have arisen. 

Response Analysis Corporation also personally 

visited several companies to offer assistance.

65
Minimizing Nonresponse

The Office of Federal Statistical Policy and Standards 

(OFSPS) encouraged an analysis of the effect of nonsampling 

error in the NIECS. An intensive effort to minimize nonresponse was the outcome of several meetings and memoranda 

dealing with the nonsampling error issue. Many of the 

following procedures were used to test the feasibility of a 

multi-wave, multicontact approach and may or may not be used 

in the larger Residential Energy Consumption Surveys (REGS). 

Most households received two letters in October 1978, prior 

to the interview. An EIA letter stressed the importance of 

the survey and a RAC letter announced the upcoming arrival 

of the interviewer.

To elicit rapport and cooperation, a $2 incentive was given 

to the respondent before the interview. Over 99 percent of 

the respondents accepted the incentive. Interviewers made 

up to eight call-backs at different times of the day and 

week. They also queried neighbors as to the most opportune 

time to contact the respondent.

A second wave was conducted in December 1978 to contact 

households that were not available during the first wave and 

to convince the first-wave refusals to reconsider. A new 

set of letters preceded the second-wave interview. For the 

second wave, a different interviewer was assigned who endeav 

ored to complete the interview by making up to five contacts.

A third wave followed in January 1979. This was an effort 

to reach nonrespondents in 14 sample locations that had low 

interview completion rates.

In a final attempt to complete an interview, an abbreviated 

version of the questionnaire, adapted for self-administra 

tion, was mailed to nonrespondents in February 1979. The $2 

incentive was included in the mailing.

In an attempt to evaluate the effects of a multi-wave, 

multicontact approach the following was noted:

• Eighty-seven percent of all responding households 

cooperated on the first wave, 12 percent on the 

second wave, and 1 percent were picked up at the 

third wave.

• Household and family characteristics such as income,

4 age of head of household, education, and geographical

*s location had little relation to the wave in which

•i the respondent completed the interview.

• Thirty-seven percent of all responding households 

required only one contact.

65
• Some fuel oil and liquid petroleum gas (LPG)

suppliers provided the fuel purchase information 

over the telephone. The telephone was adequate 

for these types of suppliers because each company 

supplied data for only a few customers and the 

fuel records were not as detailed as records for 

electricity and natural gas sales. About 600 of 

the approximately 800 fuel suppliers contacted in 

this survey were fuel oil or LPG distributors.

One unique aspect of this survey was the opportunity to 

obtain electricity and natural gas data for households that 

did not complete the interview or did not sign the waiver. 

Utilities would not supply individual household data without 

a waiver, but did supply aggregate data for groups of nonrespondents. This information provides the ability to 

analyze the potential bias introduced by nonresponse and to 

improve the accuracy of consumption estimates in the resi 

dential sector.

Weather Data

The first type of temperature data used was the 45-year 

annual average heating degree days (HDD) and cooling degree 

days (CDD) for the National Oceanic and Atmospheric 

Administration (NOAA) weather division in which the house 

hold was located (see Appendix B).

These data will aid in analyzing the effects of weather on 

personal decisions to make changes in basic housing struc 

ture or equipment. The second type of data used were HDD 

and CDD totals for each billing period. These data will 

allow more complete analysis of fuel consumption.

Weather conditions will be calculated for the appropriate 

billing period. For example, one household may be billed on 

the 1st of every month, while another may be billed on the 

5th. Obviously, there will be different 30-day averages of 

HDD and CDD for each billing period.

Editing Completed Questionnaires

Interviewers mailed the completed questionnaires to Princeton, 

New Jersey, where they were reviewed for completeness and 

correct identifying information. This manual edit was 

segmented and each part was worked on separately.

A machine edit checked for reasonable values, proper skip 

patterns, and logical consistencies.

67
Telephone calls were made to individual households to clarify 

ambiguities in the data. Additional editing resolved dis 

crepancies among the household interview, the rental agent 

survey, and the information from fuel suppliers. For ex 

ample, information on the fuel used in apartment buildings 

was taken from the rental agent survey to correct the data 

from the household. In other cases, a fuel supplier re 

ported supplying kerosene to a household not fuel oil as was 

reported by the household. The data, therefore, do not 

always represent the respondents' reports, exclusively.

All key punching was verified.

Cond-c-t4.on-4.ng is cooling air by a refrigeration unit. It

does not include fans, blowers, or evaporative cooling

systems which are not connected to a refrigeration unit.

Air conditioning units which are not currently in working 

condition or not used, but are in place in the housing unit, 

are included.

Pe.si-i.od refers to the time between meter readings.

It does not refer to the time the bill was sent or when the 

payment was to have been received. In some cases, the bil 

ling period is the same as the billing cycle which corres 

ponds closely (within several days) to meter reading dates. 

For fuel oil and LPG, the billing period is the number of 

days between fuel deliveries.

Bu.<itd>ing uu..£n 5 on. Mo^e. Hoa^-cng ttn-it& contains living 

quarters for 5 or more separate households or families.

Bu.4.lt-i,n ELnc.tn.tc. UnJ.tA . Individual resistance electric 

heating units are permanently installed in the floors, 

walls, ceilings, or baseboards, and are part of the elec 

trical installation of the building. Electric heating 

devices that are plugged into an electric socket or outlet 

are not. considered built-in.

Caulking around windows or doors whether in a heated part of 

the house or an unheated part, such as an attic or basement. 

Caulking can be done from the inside or outside of the 

house. Caulking done by the previous owner or caulking done 

to the respondent's previous home is not included.

OwYKin&k-ip. A condominium is a type of ownership

that enables a person to own an apartment or house in a pro 

ject of similar units. The owner has his or her own deed 

and, very likely, has a mortgage on the unit. The owner 

also holds common or joint ownership in all common areas 

such as hallways, entrances, and elevators.

Condominium ownership may cover single- family houses, row 

houses, townhouses, as well as apartments.

Con.6 e^ufl.£-con E^oktA are undertaken by respondents or respond 

ent's family in the housing unit the family occupies.

dissolves any buildup as it occurs.

Cool/dug Pe.gA.ee VayA are the number of degrees the daily 

average temperature is above 65 degrees Fahrenheit. Nor 

mally cooling is not required in a building when the outdoor 

average daily temperature is below 65 degrees. Cooling 

degree days are determined by subtracting the base of 65 

from the daily average temperature. For example, a day with 

an average temperature of 85 degrees has 20 cooling degree 

days (85-65=20), while one with an average temperature of 65 

degrees or lower has none.

Doom, that go outside or to an unheated area, such as an 

unheated porch, garage, attic, or basement, are included.

or professional school degree is included. Other schooling 

is included only if the credits obtained are acceptable in 

the regular school system.

Persons who have attended "post graduate" high school courses 

after completing high school, but have not attended college, 

are considered to be "Twelfth" grade graduates.

Persons who have attended more than four years of college, 

or who have attended professional schools (law, medicine, or 

dentistry, for example) are considered to have a college 

education plus graduate or professional schooling after 

completion of four years of college.

The equivalent grade of the regular American school system 

is assumed for a person who obtained his formal education 

through other systems.

For persons who skip or repeat grades, the highest grade 

attended is accepted.
