Germany
1. Overview
Responsible researcher:
Bernd Wegener, Humboldt University of Berlin
Sponsor:
Deutsche Forschungsgemeinschaft
DFG We 1019/9-1
Survey organization:
GFM-GETAS, Hamburg
Sampled respondents:
German citizens aged 18 and above who have permanent
residency in the Federal Republic of Germany
Sample size:
N = 1.337 in the East
Proportionally weighted
sample size (V2139):
Proportionally re-weighted
sample size (V2145):
N = 250 East
Sample selection method:
Three-stage random probability household sample using 210
sampling points in the East and the West respectively (stage 1), a
random-route procedure to locate households (stage 2), and a
random selection method to determine a person within a
household (stage 3).
Completion rate:
West: 67.2 %
East: 72.0 %
Response rate:
West: 86.4 %
East: 90.7 %
Questionnaire method:
Face-to-face interview with completely standardized
questionnaire
N = 1.704 West
N = 421 East
Questionnaire construction: In both East and West an identical questionnaire was used, some
questions however had East-West split versions; a pretest of the
survey, in particular for time estimates, was carried out on 20
quota-sampled respondents; questions not included in the 1991
survey were translated into English and back into German.
Language:
German
Interviewers:
151 trained professional interviewers carried out the interviews in
the East and the West respectively; of these, two interviewers
worked in both parts of the country
Field dates:
November 16 to December 31, 1996;
121 interviews between January 1 and January 15, 1997 (106

Mean length of interview:
West: 62.8 minutes
East: 60.2 minutes
2. Sampling Method
Sampled respondents were German citizens aged 18 years and older who have permanent
residency in the Federal Republic of Germany and live in private households. It was decided
to aim at 1.000 completed interviews in West and East Germany respectively, i.e. to have a
disproportional sample design with the total of 2.000 analyzable cases. Given the actual
number of inhabitants in East and West Germany this amounts to oversampling East Germany
by a factor of about 2.5.
The sampling frame was the stratified three-stage ”ADM Master Sample Plan” which, in its
first stage, randomly selects 210 voting districts that are used as sampling points and
constitute a ”net”.1 The present study used two ”nets,” i.e. 210 sampling points in the West
and 210 sampling points in the East.2 To achieve 2  1.000 interviews, five interviews had to
be carried out in each sampling point.
The second selection stage called for determining the households within voting districts. This
was done by a random-route procedure. Interviewers were given a randomly selected starting
address from which they had to walk on according to a specified ”walking rule” and had to
list every third household address on an ”address matrix sheet” until 23 addresses were listed.
Eight of these addresses, which fell on randomly pre-marked cells in the matrix, had to be
contacted. Thus eight times the number of sampling points (8  210 for East and West
Germany respectively) is the total sample size of addresses.
Finally, in the third selection stage, the interviewer had to decide which person in each
household was to be the one interviewed. In households with more than one person, this was
determined through a ”Kish grid”, that gives each member of a household an equal chance of
being selected.
1
Sampling points in the ADM design are drawn in a stratified random selection process that involves three
regional types of districts (Länder, Bezirke, Kreise), size of community and urban districts, and number of
households within voting districts (Kirschner 1984: 121).
Usually one ”net” is thought to be sufficient for sampling 1.000 respondents. Note that in the 1991 German
ISJP survey two ”nets” were used in East Germany to cover an N of 1.000 because sampling information was
sketchy at that time. It could be assumed that in 1996 this situation had changed and that the number of sampling
points could safely be reduced.

The completion rate is therefore 67.2 % in the West and 72.0 % in the East.
We define the response rate as the number analyzable cases divided by the sample size of
contacted individuals, i.e. the net sample size minus the total of noncontacted individuals. The
response rate is 86.4 % in the West and 90.7 % in the East.

Interviewers conducted an average of 7.1 Interviews – 6.5 % in the West and 7.5 % in the
East. 20 Interviewers in the West and 21 in the East conducted over 11 interviews.
83 % of interviewers covered either one or two sampling points.
The survey institute (GFM-GETAS) routinely performs interviewer controls by contacting
respondents having them fill out a written questionnaire about the interview. This is done
each time after an interviewer has participated in a maximum of 10 different studies or after a
nine months interval has elapsed since the last control. A control run involves all of the
interviews an interviewer has conducted. On the basis of these controls, two interviews were
decided to be not analyzable; unfortunately, these two interviews had been conducted in two
sampling points in which no other interview had taken place. These two sampling points
could not be replaced.

The mean interview time was 60.2 minutes in the East and 62.8 minutes in the West.
6. Weights
6.1 Institute Weights
The survey institute provided a weight variable for the data set (V2139). This weight variable
accomplishes two things: it corrects for the selection bias due to household size (respondents
within large households have a smaller chance of being selected than respondents from small
households) and it corrects for distribution skewness produced by refusals and other nonneutral reasons for not completing an interview. For this latter correction the weight
construction uses an iterative proportional fitting procedure by which observed combinations
of respondent attributes are fitted to tables of combined attributes of other large data sets, e.g.
census data.
Based on census data of 1995 (December 31, 1995) the following variables were employed in
the fitting procedure: länder, community size, and respondent’s sex and age. Based on the
East's six länder and the West's 11 (counting West and East Berlin as two separate länder), on
five classes of community size and on five age groups, the Western weight matrix contains
223 and the Eastern matrix 122 cells.

In order to confirm the validity of the weight, we can compare weighted results with census
results and nonweighted results. (Of course, in order to be precise, the complete matrices of
the attributes combined should be compared.)

6.2 Alternative Weight Construction
After the 1996 data set had been produced an alternative weight variable was created that
would be applicable to both the 1991 and the 1996 surveys. It should be noted that in 1991 a
different survey institute (infas, Bonn) was involved. This meant that statisticians of both
institutes had possibly used different fitting procedures and different break-down categories
for the tables. Another problem was that it could not be reconstructed whether in 1991 a table
of all possible combinations of attributes was used for an iterative simultaneous fit,
considering all possible interactions, or whether independent runs for some of the attributes
were made. Finally, in working with the data from the two different years consideration had
to be given to the fact that in 1991 the East had been overrepresented by about 1.5, whereas as
in 1996 the overrepresentation was 2.5.
Joining the 1991 and 1996 data sets, therefore, a new weighting variable for the East and the
West was constructed (V2145), also based on iterative proportional fitting involving länder,
METHODS OF THE 1996 ISJP

community sizes, sex, and age.3 The new weighting scores for 1991 and 1996 are distributed
in the following manner.
The new weighting scores should be used when comparing East and West Germany across the
two time points of measurements. The following results validate the weighting results for
some combinations of attributes.

Face to face interview
The ISJP 1995 survey was designed and carried out as a separate
survey, i.e. the ISJP questionnaire was not made part of a larger
survey. A special section on political attitudes and voting
behavior was added at the end of the questionnaire.
2. Sampling
Three stage random sampling. In the first step, locality was chosen by random, in the second
step a particular address and apartment was chosen by random. The selection of the
respondent was made from the list of all members of the household older than 18 years (the
list was prepared by an interviewer) using the date of birth as a selection criterion (a person
on the list with the closest birthday).
Total sample: 1 600 addresses

2. Sampling Method
2.1 The three-leveled, accidental walk sampling method.
This method provides a quick and economical way to select the respondent, precluding
possible subjective points, and forming the sample on all levels. This method does not
provide a representative sample from the point of view of age, gender or education. In order
to achieve a greater representation, the given data has to be weighed with the exact values of
the above mentioned variables, gained in a census.
2.1.1 Level I.
The choice of sampling points
We could term this level "creation of a settlement sample". The differentiation in the title
shows that there are different possible sampling points in a given settlement. In this case for a
national sample of 1000 (persons) we chose 100 sampling points, in a way that during each
accidental walk, starting from the sampling point, 10 questionnaires had to be completed.
This level of sampling is done by the help of a computer program. It uses a datafile, which
contains the names of all the settlements in Hungary and the number of their inhabitants.
Within the file the settlements are organized according to their region and their Central
Statistical Office (CSO) identifier. This organizational arrangement makes it possible for the
regions to be represented in the sample according to their population size, as well as the CSO
identifier, as normally its definition does not provide any order to the listing of settlements.
The algorithm works in a way that the rate of probability of being chosen is related to the size
of the population of the given settlement.
METHODS OF THE 1996 ISJP
20
2.1.2 Level II.
The choice of the starting point of the accidental walk
The starting point of the accidental walk is a junction or a concrete address. The description
of the walk can be found in the second insert. These are the directions for the researchers
conducting the questionnaires. This phase of sampling proceeds with the help of a map. Yet
there are no maps for public use for the majority of villages. In these settlements we usually
choose a public building as a starting point. In the given example we have chosen a random
address from the telephone book. This method is better than the commonly used one, but
because of the limited spread of telephones we were not able to select from all of the
households within the settlement.
2.1.3 Level III.
Selection of one person from the members of a household
Our aim is to represent all the members of a household with the same probability. This can be
realised with the aid of a series of tables worked out by an American statistician, Leslie Kish.
Of course, the use of Leslie Kish's key reaches its goal only when the questionnaires are
numbered. The rule of repeated visits and other regulations are observed and in this way the
mobile respondent, who can rarely be found at home, has the same chance of selection
as the immobile ones. The detailed regulations of the choice can be found in the second insert,
and the tables of Leslie Kish in the third insert. The output in the fifth insert, which is given
on a disk in a separate file, contains the settlements chosen by the help of the program, and
also the starting points belonging to them. In the first column of the table there is the four
CSO identifiers. The second is the code of the county (see the first insert). We indicated the
code of the extent of the settlement with TN. Its description is in the fourth insert. The
column which is marked with T3 contains a simple settlement-type code. 1- the capital, 2 city, 3 - village. In the sixth column the size of the population can be found. The seventh
column contains the codes of regions described in the first insert. Finally, the last data is the
starting point.
2.2. Insert Sampling regulations
The sampling method in the given research is the usual three-leveled accidental walk method.
Its aim is to provide a representative sample with the help of chance. It can be fulfilled only
if the person conducting the questionnaire completely follows the method described below,
and does not choose a nicer house if the selected according to the procedures is a run-down
hut with a barking dog. The first level is to choose the settlements with the help of a
computer program. At the second level we choose starting points in the settlement by chance.
The third level is to choose the person who will be interviewed from the marked household
with the help of the Kish key. The researcher starts his/her work at a given starting point. It
can be a junction or a concrete address. In the event it is a junction, start to walk on a street
which was mentioned first, in any direction. If it is a concrete address or building, face it and
go right. In villages and in certain parts of cities where houses have gardens (where one
house usually means one household, ) try to find a person to be interviewed at every fifth
house. If it is clear that there is more than one family living in the house, take it into
METHODS OF THE 1996 ISJP
21
account. In the densely built up regions go to every 15 households. This can be done if you
continuously count the post-boxes or the list of tenants. Start counting with the first flat on
the ground floor. During the accidental walk, move only on one side of the street. Turn at
each junction. First to the right, then to the left. You have to change direction to avoid going
in a circle. In case of any hindrances - no more houses, a dead-end, a factory gate, etc. - make
a U-turn to the other side of the street and continue your walk in the same way.
Before beginning the questioning process, please arrange the questionnaires according to
ascending numbers. They must be given in this order. How should adults from the same
household be chosen? To do this, you need three data. On the title page of the questionnaire
there is a circled, sample code to indicate which key has to be used out of the six. In the
intersection of the column corresponding to adults and the line corresponding to the number
of men you can find the right person. For example: On the next questionnaire the circled,
sample code is 4. In the given flat there is a young couple with two children in nursery school
and a grandmother. So, the number of adults is three, and there is only one man. According to
Key 4, in the intersection of column 3 and line 2 the man has to be given the questionnaire.
He has to be interviewed, even if he is not at home. You can arrange a time with the other
members of the family and return - in this case you have to store away this questionnaire
because you have chosen him with the given sample code; with the other sample code of
another questionnaire another person would have been chosen. It is also possible that he is
not accessible during the questionnaire process. (Soldiers, students living in a dormitory, etc.
who are temporarily away are also parts of the household!) In this case do not ask anybody
else from the family! You have to follow the regulations. If not, it can lead to the deformation
of proportions in the sample - i.e. too many pensioners and mothers on maternity care. If the
person is not accessible, you have to continue the procedure in the following 15th or 5th
household. It is possible that you will find nobody in the given flat. You have to try two more
times at different times of the day, but it is always good to ask the neighbors about their
habits. You need the name and address of the people being questioned because it must be
checked. The data is processed by strictly guaranteeing anonymity and is used only for
statistical purposes. Please consider your colleagues and be careful with your handwriting.
3. Type of Interviewers
The survey institute is working with part time interviewers. They have been
working for the company for a long time and before the employment they had to take
an intensive training and pass an exam. This network of the interviewers has been
working for more than 20 years. The instructors are responsible for the different
regions of Hungary are in full time positions. The number of regions are 20.
Instructors randomly selected names from the sample (the average was one
from six) and checked the interviews after it was completed. The control covered the
following problems:
- selection of respondents were correct or not according to the Leslie Kish key
- they checked some socio-economic factor
- the length of the interviews
4. Weighting
Weight variable is provided (v4100) which adjusts for differences in occupation status. As
finally inactives were over-represented in the sample, following the 1990’s Hungarian census
data we developed a weight variable calculated by cross-classification of gender and
employment status.

5. Country Specific Coding
Hungary has not asked the following questions:
- curr.job month start (v38)
- last job month start (v50)
- partner’s job month start ()
- set of questions concerning previous job (v55-v66)

2. general formal education with basic vocational training (in Hungary: elementary school
with technical school training)
3. medium vocational with medium formal (in Hungary vocational training with maturitas)
4. secondary formal education (in Hungary: high school - gimnazium, with maturitas)
5. lower tertiary (in Hungary: academies, 4 years long)
6. higher tertiary (in Hungary: universities, 5 years long)
5.3 Political Parties
1. liberal parties: SZDSZ (Alliance of Free Democrats)
2. MSZP (Hungarian Socialist Party - social democrats)
METHODS OF THE 1996 ISJP

3. FIDESZ (Young Democrats - centrist liberal party with conservative political orientations
4. MDF (Hungarian Democratic Forum, conservative party) and KDNP (Christian
Democratic Party, also conservative)
5. conservative parties FKGP (Smallholders Party which is a populist right-wing conservative
one)
If you want to have a scale from socialism to conservativism, simple recode 1 to 2 and 2 to 1.
Than the Hungarian Socialist Party will be the first and the Alliance of Free Democrats will
be the second.

At the third stage interviewers made route search of private households. The selection of
respondents was made randomly (a member of HU whose day and month of birthday was
closer to the day of the interview was selected). In case of absence of the needed member of
the household, after two callbacks the interviewer selected a new household by the same
method.

3. Interviewers and Fieldwork Method
The work of every interviewer was controlled by telephone or a callback in the proportion of
1 per 10 interviews. No interviews have been excluded as a result of the control.
Occupational coding was done by the trained staff in the fieldwork department in VCIOM’s
central office.
Backtranslation was done only for the new variables (not in the 1991 questionnaire). Pretest
(20 respondents) was made to test the average length of the interview. The survey was

6. Methodological Issues in Russia
1. The Russian data in 1991 was NOT weighted.
2. The differences between the sample design in the two Russian survey is that in 1996 at the
last stage interviewers made route search of private households. The selection of
respondents was made randomly (a member of houseunit whose day and month of birthday
was closer to the day of the interview was selected). In 1991 the selection was made on the
basis of militia registration books (at present they are unavailable).
3. The question wordings were different in the following cases:
26e. ‘Prejudice and discrimination against certain groups of people’ (in payment for work,
applying for jobs) The part in brackets was added in 1996 to make the question clearer.
26f. Lack of equal opportunities’ . In 1991 the wording was ‘the fact that different groups of
METHODS OF THE 1996 ISJP
36
people don’t have the same opportunities to get good education and work’. In 1996 it was
changed to ‘the fact that not everybody have the same opportunities to get good education and
work’.
31f. ‘The part of the country you are from’ (whether you are from a village and not a city, if
you are a refugee etc.) The part in brackets was added in 1996.
32b. ‘There is an incentive for individual effort only if differences in income are large
enough’. In 1996 ‘incentive’ was translated as ‘stimuli’, in 1996 – ‘the will to work well’.
33g. ‘Being a man and not a woman in 1996 was translated as ‘Sex of the employee (male
or female).’
35a. ‘The government should guarantee everyone a minimum standard of living’ in 1991 was
translated as ‘guaranteed standard of life’, in 1996 it was changed to ‘a minimum standard of
living’ since the later expression became, contrary to 1991, a part of standard vocabulary.
35b. ‘The government should place an upper limit on the amount of money any one person
can make’. In 1996 it was supplemented by (and not allow anybody to make more than this
limit).
35c. ‘The government should provide a job for everyone who wants’ one formulated in 1996
as ‘The government should provide a job for everyone who can and wants to work’.
46d. ‘Attended a public meeting’ was translated in 1991 ‘attended unofficial public meetings’.
In 1996 ‘unofficial’ was deleted (as such a phenomenon as official public meetings
disappeared).
46e. ‘Joined an unofficial (wildcat) strike’ in 1991 was translated as ‘joined a strike’, in 1996
– ‘participated in a strike’.
46h. ‘Written to your member of legislature’ was changed into ‘applied to your member of
legislature’.
48c. ‘In (COUNTRY) a poor person has the same chance of a fair trial as a wealthy person
does’ was put in 1991 as ‘in our country a poor person has the same chances of a fair
treatment in court, as the rich person does’. This was changed in 1996 into ‘in our country a
poor person can rely on the same fair treatment in court, as the rich person does’.
50b. ‘In (COUNTRY) people get rewarded for their effort’ was translated in 1996 as ‘In our
country effort is rewarded’.
50d. ‘In (COUNTRY) people get rewarded for their intelligence and skill’ was translated in
1996 as ‘In our country effort and skill are rewarded’.
51e. ‘People are entitled to pass on their wealth to the children’. Since the concept of
entitlement does not have a direct translation into Russian, in 1991 it was translated as
‘People have the right to pass on their wealth to their children’. In 1996 it was formulated as
‘People must have the right to pass on their wealth to their children’ to make it look like a
normative statement and not the observation about the real state of things.
52e. ‘The way things are these days, it is hard to know what is just anymore’ was translated in
1996 as ‘These days it is hard to judge what is just, and what isn’t’.
E1. ‘Based on your experience in (COUNTRY) of socialism , would you say that you are very
much in favour ...’In 1996 ‘of the socialism that existed in our country before 1985’ was
inserted after ‘in favour’.

2. Sampling Method
The sample size is N = 1636 (Planned N = 1750). It is a two-stage cluster sample with
preliminary stratification of clusters by two technical variables: the region and the type of
settlement. The sample is based on the list of the electoral sections used in the last municipal
elections of October 29, 1995, which total 13,082, and out of which 250 primary units
(clusters) were chosen at random, with probability proportional to the size of sections. Within
each cluster the plan was to interview 7 persons, to yield a total sample of 1750 persons. The
respondents within the clusters are chosen at random. Each interviewer was supplied with the
names and the addresses of 10 possible respondents per cluster (electoral section), out of
which up to 7 were to be interviewed, but in cases where less than 5 from the list were found,
interviewers sought out appropriate replacements (of similar sex and age) within the unit. The
interviewers were instructed to record the necessary information for all inaccessible
respondents.

There were three inaccessible clusters in the sample which were replaced by quota (16
interviews). Two clusters from Plovdiv region, very difficult to penetrate due to large Gypsy
population, and 1 cluster in Kardjali region, inaccessible due to flooded roads. One other
METHODS OF THE 1996 ISJP
39
cluster was simply missing because of complications with the interviewer (No 027 - Sofia
region).
The average interview length is 55 minutes.
No pretest was conducted.
4. Interviewers
The survey was conducted employing the national interviewer net of VR. The net
consists of 28 regional teams, each having a team head experienced in fieldwork. All the
interviewers have undergone the necessary training and have a considerable experience. For
the solution of specific problems interviewers were instructed to contact the head of the
regional team or the staff members of Vitosha Research, Sofia.
The majority of interviewers have a university education in the social sciences
(sociologists, psychologists, etc.), and rich fieldwork experience. The remaining part also has
rich fieldwork experience, and has passed various fieldwork training courses.
The briefing session with the heads of the regional teams and part of the interviewers
was held on November 30, 1996. It included an overview of survey methodology, specific
features of the questionnaire and of specific questions, sampling methodology, specific
fieldwork requirements, and the reconstruction of a fieldwork situation. The interviewers
were supplied with written instructions and show-cards. The fieldwork started on November
30, 1996 and finished on December 14, 1996.
5. Weights
There is a minimal diversion of data from the basic socio-demographic parameters of
the population (a provided by the National Statistical Institute). In this case no weighting is
necessary and no weights have been provided for the 1996 data.
1991 weights have been calculated using 1992 Bulgarian Census data below.

6. Quality Control
6.1.
Direct Control
The direct fieldwork control was conducted by VR supervisors. The principal tasks of
the supervisors were to control the fulfilment of the sampling plan and the work of the
interviewers. The overall impression is that the sample was covered according to the plan,
except for some minor deviations.
6.2.
Logical Review of the Questionnaires and Data Entry
All questionnaires were subjected to a logical review before data entry. The logical
review was carried out by VR staff and included:
- fulfilment of all questionnaire instructions
- logical correspondence between answers of different questions
- control for accuracy in the cases where there is objective information (e.g.
questions on size of the city/village, administrative region).
Coding of open-ended questions was completed simultaneously with logical review.
Questionnaires were processed using double entry procedure (employing a specialised
DBASE program).
The final data file was further processed to re-check for matching the requirements of
filter questions.
Coding for all variables in the data file follows the enclosed codebook. All “0” values
should be treated as “missing”, except if the “0” is not defined with a specific label. This
applies to filter questions where answers of respondents skipping a question are coded with
“0”.

7. Field Log Summary and Comments
1.
As a whole, no serious or unusual problems were encountered during the different
stages of the survey.
2.
Interviewers’ opinion
The field log included a questionnaire focusing on specific difficulties during the
fieldwork. The remarks of the interviewers concerning the attitudes of the respondents
towards the questionnaire as a whole and towards some questions are as follows:
2.1. Only some old men (over 70 years), inhabitants of villages and respondents of
Turkish and Gypsy ethnic origin faced difficulties in understanding certain questions.
2.2.
As a whole the number of the refusals was low and in most cases occurred in
towns.
2.3. Some respondents aged 65 and over and living in smaller settlements were
afraid to express what they really thought, because of fear of bad consequences for them.

8. Country Specific Coding
Variables in the new file could be grouped in the following categories:
1. Variables that do
not exist in the
Bulgarian
questionnaire and
have been assigned
“0” and the same
length.
V38-V41, V50-V51, V55-V66, V153, V161,
V402-V410, V412-V430,
V432-V440, V517-V549, V553-V691,
V693, V801-V930, V932-V940
2. Specific recoding
cases and exclusions
V32 (variable replicated in V1003), V44,
V72, V699:
Categories 10 through 14 have remained
unchanged because it is impossible to
change. 1 dekar = 1000 square meters.
V189(repl V1045), V231 (repl V1048), V695
(repl V1044).
The recoding scheme employed does not
match classic criteria. The principle used
is to label “conservative” those parties
which are more or less trying to preserve
the socialist past (i.e. former communist
parties), and to label as “liberal” those
who are aiming at fast and far reaching
market reforms. In this way the
classification becomes:
BSP = 5
UDF = 2
MRF = 3
DAR = 4
PU = 2
BBB = 2
FKB = 3
V29 and V69
The categories “working pensioners (full
time and part-time)” does not exit in the
Core Codebook. For these variables the
above categories have been recoded into
option 6 “retired”. However, as this
affects the following questions (this is a
filter question) the values for the
affected variables have been changed and
this will affect the respective
distributions. The unchanged versions are
replicated in the Bulgarian section.
V43, V71: Please note that the original
filter in the Bulgarian questionnaire is
at option 6 (on training scheme….).

Additional Comments
The variable weight has been computed after the merging of all files, and contains relevant
weights from any countries that included weights in their data. It is the appropriate weighting
variable to use. It was constructed by combining v2139 (German 96 weight), v4100
(Hungarian 96 weight), v11009 (Russian 96 weight) and w1 (Bulgarian 91 weight).
