employers and unpaid family workers. Inthis report all self-
employed are classifted together.
Labour force participation. The following interpreta-
tion of the ILO defínition of labour force status is used in the
Labour Force Survey:
Employment. All gainíul employment including unpaid
work at family enterprise, unpaid work with the construc-
tion of own house or for the production of own consumption.
Also creation of works of art, even if the persons has not yet
received any payment. Maintaining own household is not
considered gainful employment.
Unemployment. Persons are classified as unemployed if
they did not have gainful employment in the reference week
and satisíy at least one of the following criteria:
1. Have actively been seeking work during the previous
four weeks and are able to start working within two
weeks. No distinction is made between active and
passive methods of job search.
2. Have already found a job which begins later.
3. Are on temporary layoff.
4. Have given up seeking work but can start working
within two weeks of finding a job.
Students only satisfying criteria 2 - 3 are not considered
unemployed.
Employed. Persons are classified as employed if they
worked one hour or more in the reference week or were
temporarily absent from their work during that week. Per-
sons on matemity or patemity leave do not have to retum to
their previous job.
Inactivepersons. Persons are classified as inactive if they
are neither employed nor unemployed according the criteria
above.
The labour force consists of employed and unemployed
persons.
Residence. Information on residence is taken from the
National Register and updated at the time of the survey with
information from contact efforts.
The capital region consists of following municipalities:
Reykjavík, Seltjarnarnes, Hafnarfjörður, Bessastaða-
hreppur, Garðabær, Kópavogur, Mosfellsbær, Kjalames-
hreppur and Kjósarhreppur.
The following municipalities are classified as towns
outside the capital region, usually with more than 1,000
inhabitants:
Keflavík, Grindavík, Sandgerði, Njarðvík, Akranes,
Borgames, Stykkishólmur, Olafsvík, Isafjörður, Bolungar-
vík, Blönduós, Sauðárkrókur, Siglufjörður, Akureyri, Dalvík,
Ólafsfjörður, Húsavík, Egilsstaðir, Seyðisfjörður, Eski-
Qörður, Neskaupstaður, Höfn í Homafirði, Selfoss, Hvera-
gerði and Vestmannaeyjar.
Municipalities other than the above are classified as other
municipalities.
Marital status. Classification of marital status is as
reported. Correction is made when reported marital status is
logically incompatible with information from the National
Register, e.g., when a respondent reports him or herself as
married without being recorded as married in the National
Register, that person would be classified as cohabiting.
Education. Primary education is classified in ISCED
groups 1-2. Vocational education, such as apprenticeship in
crafts, as well as 1 to 3-year general education after primary
education is classified in ISCED group 3. Higher vocational
training and university entrance exam (generally fmished at
19-20 years of age) is classified in ISCED group 5. Univer-
sity education and equivalent education is classified in
ISCED groups 6-7.
Students. A respondent is classified as a student if he or
she attended day school within the four week period prior to
the survey, had a vocational training during the same period
or reported that he or she was a student having a part-time
job.
Occupation. Occupation of first job and last job is coded
according ISCO-88, as adapted to Icelandic conditions. All
cases are coded at unit group level, but reported at major
group level.
Full-time/part-time employment. A person is full-time
employed if he or she usually works 35 or more hours per
week. Part-time employment is 1-34 usual working hours
per week.
Working hours. Calculation of average number of actual
working hours is made only for those employed persons who
worked one hour or more in the reference week in either
their first j ob or second job. Missing data have been imputed
by multiple regression analysis, using sex, full-time/part-
time employment and occupation as independent variables.
10.1.5. Weighting, estimation of totals and annual aver-
ages
Annual averages are calculated from both surveys within the
year. Totals and percentages are estimated by applying
weights to each case. Weights are calcuiated with Formula
9.1, where
Jy = mean population aged 16-74 years,
n = number of respondents,
n* = number of sample individuals with domicile in
Iceland but residence abroad,
k = sex of respondent,
a = age group of respondent {16,17,18-19,20-24,25-29,
.., 65-69, 70-73, 74 years} and
m = {April survey, November survey}.
10.1.6. Difference between present figures and previ-
ously published figures
The estimation of totals and percentage distribution in this
report differs from previously published ILFS figures. This
is mainly due to the following reasons:
1. All existing data have been reedited to remove incon-
sistencies and errors.
2.1tem non-response has been removed by imputation.
The method of imputation is either logical analysis of
other responses by the same respondent or analyses of
responses of other respondents, e.g. by regression analy-
sis. This has mainly affected estimation of the number
of working hours, as this has shown non-response bias.
3. Responses that have been inconsistent with external
sources, e.g. marital status recorded in the National
Register, have been corrected.
4. Coding of economic acti vity, occupation and education
has been revised.
5. Complex variables, such as labour force status, have
