Study: EU-LFS 2004

Titles

Title European Union Labour Force Survey 2004

Abstract

EU-LFS 2004 contains the Module on Work organisation and working time arrangements.

The study group consisted of employed persons, the self-employed, employees and unpaid family workers.

Coverage

Geographical Coverage

The EU-LFS 2005 covers "the [then] 25 Member States of the Union. In addition the survey covers member states of the EEA, Iceland and Norway, Switzerland by bilateral agreement, as well as the Candidate Countries, Bulgaria, Croatia, Romania and Turkey." (Eurostat (2006): Quality report of the European Union Labour Force Survey 2004, p. 2).Turkey and Malta are not included in the micro-data.

Time Period Covered

The reference week is one week in each quarter starting on Monday and ending on Sunday. In all countries but Germany, Hungary (3 weeks/month), Bulgaria, Croatia and Turkey the sample is spread over the 13 weeks of the quarter. [...] The first week of a year or quarter is defined as the week that includes the first Thursday of the year or the quarter." (Eurostat (2006): Quality report of the European Union Labour Force Survey 2004, p. 4.)

    Non-response Weight: Method

    The initial weights are calculated according to the sample design, with all persons within the same PSU having equal design weights. The design weights are adjusted using the data of response level in each PSU.

    Coverage Adjustment Weight: Method

    These weights are then adjusted on the basis of demographic data. Demographic data are broken down by degree of urbanisation, age groups and sex for adjustment of the quarterly weights. For adjustment of the yearly weights demographic data are broken down by degree of urbanisation, age groups and sex as well as in NUTS 3. All persons within the same household have equal initial weights, but the final weights tend to be diverse.

    The strata result from the crossing of the canton and the
    household size class. There are 13 cantons in Luxembourg. The household size is divided into four classes. So, the product of the number of cantons (13) and the number of size classes (4) gives 52 strata.

    Coverage Adjustment Weight: Method

    A calibration is performed with CALMAR macro of INSEE-France for correcting the non-response at the household level. Among many variables like region, household class size, age of reference person and citizenship of reference person, it should be found out, by logistic regression, by how much they account for the non-response phenomen. The variables canton, size of household, and age of the reference person are selected. Three regions are determined by grouping some cantons. The final adjustment consists of making the most recent distribution of sex * age class * citizenship in the population agree with the distribution of the same variables in the set of respondents. This calibration is implemented at the person level.

    For any stratum of the sample, the unique design weight is defined as the ratio of the total number of dwellings in the stratum to that in the sub-sample for that stratum.

    Coverage Adjustment Weight: Method

    Calibrated weights are determined with the method of generalised raking. For each of the 20 geographical units, the calibration variables or controls are totals for age-sex groups, total number of household and total resident population in cities with 50 000+ inhabitants. The calibration is organised so that all members in a sample household have the same calibrated weight as that household.

    A two-stage adjustment procedure is used.
    (a) If possible, limited data are collected for households which fail to respond. These data can include: number of members of the household, nationality, and for households comprising only one person: age and sex. From this data, the weightings of respondent households are increased to take account of non-response in the region.
    (b) The sample, weighted to take account of non-response, is stratified a posteriori by region, sex, age and nationality and is extrapolated to the population.

    Non-response Weight: Method

    The three strata are weighted separately. For Stratum 1) the register-based information age, education and gross income is used to derive initial non-response weights. For Stratum 2) age, gross income and group of industry is used.

    After this step weighting is performed by using a combination of sex and mainly 5 years age groups for the 3 sampling strata separately, based on the Population Register.

    The adjustment procedure is based on a three-stage a posteriori stratification. Figures are based on independent demographic estimates. The stratification variable for the first stage is the Local Authority District or Unitary Authority. This stage makes it possible to make adjustments for different rates of non-response in the various local authority areas and ensures that the results are geographically representative. The second-stage variables are sex and age group. This stratification is intended to ensure that the age profile of the 16-24 year old is correct at national level. The variables in the third stage are region, sex and age group. The three stages are applied by means of an iterative procedure designed to ensure that the estimates are consistent with the stratification variable sets.

    Stratification Criteria

    In each Department (NUTS 3), the stratification of primary units is
    conducted by allocating the Municipalities and Communes
    according to the degree of urbanisation. Except for the two major city agglomerations (Athens and Thessaloniki) the strata produced according to the degree of urbanisation are: urban stratum, semi-urban stratum and rural stratum. Athens and Thessaloniki are divided into several strata on the basis of the lists of city blocks of the municipalities and taking into consideration socio-economic criteria.

    Non-response Weight: Method

    Every quarter, population projections by age group and Spanish provinces (NUTS 3) are calculated. Projections by age and region are distributed by stratum in proportion to the population of each stratum. In each stratum, age group and region, the weighting is determined by the ratio of the projection to the sample size.

    Coverage Adjustment Weight: Method

    The sample is calibrated in order to adjust to the population disribution. The auxiliary information used is the population by sex, age, nationality and NUTS 2. A linear weighting method is used, in which each member of the household has the same weight.

    Inverse of selection probability

    Non-response Weight: Method

    For non-response adjustment the non-response correction factors are computed. The homogeneous response groups of reasonably uniform size of sampled households are formed on the basis of the place of residence of the household according to the non-response rate in the region. Within each group the correction factor is inversely proportional to the overall response rate in the region.

    Coverage Adjustment Weight: Method

    The weights are calibrated so that they produce exact population numbers in certain subgroups known from demographic data (including institutional population). For working-age persons the subgroups by sex, age, place of residence and Estonians/non-Estonians are considered. For this purpose the linear consistent weighting method is applied. For non-working-age persons the non-response adjusted household's weights are calibrated by sex and age.
