Coverage
Coverage Inclusion/exclusion criteria for members of the household Questions relating to employment status are put to all persons aged ...
 The population 16-74 with permanent (more than 6 months) residence in Iceland.  -  16-74

 

Reference week
 The quarterly sample is sorted according to sex, age and residence and then allocated systematically (with random start) to the 13 weeks of the quarters so that each week is representative of the total sample by age, sex and residence.

 

Sampling design & procedure
Sampling design Base used for the sample (sampling frame) Last update of the sampling frame Primary sampling unit (PSU) Final sampling unit (FSU)
 Single stage random sample of individuals  The population register, persons with registered domicile on the last day of the previous quarter.  National Register updated daily. New sample is drawn week before each quarter begins.  -  Individuals

 

Sampling design & procedure
First (and intermediate) stage sampling method Final stage sampling method Stratification Description of the rotation scheme
-  Single random sample without replacement of persons younger than 75 in the first week of the quarter and older than 16 in the last week at the end of the rotation cycle. Persons younger than 16 on the last day of the reference week are not included in the weekly sample until this age is reached.The household sub-sample is selected from the fifth and last wave so that the sampling probability is inversely proportional to the number of persons aged 16-74 years in the household of the drawn individual.  -  3-(2)-2

 

Sample size & Sampling rate
Overall theoretical yearly sampling rate
(i.e. including non-response)
Size of the theoretical yearly sample
(i.e. including non-response)

Sample size & Sampling rate
Overall theoretical quarterly sampling rate
(i.e. including non-response)
Size of the theoretical quarterly sample
(i.e. including non-response)
 1,9%  4030

 

Use of subsamples to survey structural variables (wave approach)
Only for countries using a subsample for yearly variables
Wave(s) for the subsample Are the 30 totals for ILO labour status (employment, unemployment and inactivity) by sex (males and females) and age groups (15-24, 25-34, 35-44, 45-54, 55+) between the annual average of quarterly estimates and the yearly estimates from the subsample all consistent? (Ref.: Commission Reg. 430/2005, Annex I) (Y/N) If not please list deviations List of yearly variables for which the wave approach is used (Ref.: Commission Reg. 377/2008, Annex II)
       

 

Data collection methods: brief description Participation is voluntary/compulsory?
Centralised CATI for three weeks after the reference week  Voluntary

 

Brief description of the method of calculating the weights Is the sample population in private household expanded to the total population (including those in collective households)? (Y/N) Gender is used in weighting (Y/N) Which age groups are used in the weighting (e.g., 0-14, 15-19, ..., 70-74, 75+)? Which regional breakdown is used in the weighting (e.g. NUTS 3)? Other weighting dimensions
