Study: EU-LFS 2002

Titles

Title European Union Labour Force Survey 2002

Abstract

EU-LFS 2002 contains the Module on Employment of disabled people.

The target population consists of the persons aged 16 to 64.

Coverage

Geographical Coverage

Time Period Covered

Since 1998, the transition to a quarterly continuous survey (with reference weeks spread uniformly throughout the year) has been gradually conducted by Member States. Some countries first introduced a continuous annual survey (meaning the reference weeks were uniformly distributed throughout the spring quarter) and then switched to a quarterly collection, whereas others moved directly to a quarterly continuous survey.

    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.

    Non-response Weight: Method

    The initial household design weights are adjusted by the use of auxiliary information relating to population data on the intersection of age groups, sex and 10 NUTS III (counties) as well as data from the National Labour Exchange on the number of registered unemployed persons. Each member of the household receives the same weight as the household.

    Coverage Adjustment Weight: Method

    The weighting method is based on the generalised calibration method introduced by Deville and Särndal in 1992. The calculation of the calibrated weights is carried out with the use of the SAS macro program CLAN, developed by Statistics Sweden.

    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.

    Stratification Criteria

    The primary units were stratified by crossing 21 regions and
    10 categories of commune.
    For the second level, in the rural cantons and the urban units
    with fewer than 10 000 inhabitants, in each primary unit
    sample, communes with fewer than 160 dwellings were
    combined with adjoining communes. A commune (or group
    of communes) was then drawn with a probability proportional
    to the number of dwellings.
    In each urban sample with more than 10 000 inhabitants, a
    list of census districts was drawn up, showing the number of
    dwellings. After a calculation of the quotient between the
    number of dwellings in the urban unit and the number of
    areas to be drawn there, districts were segmented in as
    many portions and a sample district in proportion to the
    number of houses was drawn in each portion. The same
    principle was applied to urban areas with more than 100 000
    inhabitants.
    The final level of sampling consists in cutting out the
    secondary unit in areas with between about 80 to 160
    dwellings according to the strata.

    Each of the three sub-samples is adjusted in line with the population pyramid at the time of the survey, by sex and five-year age group.

    Coverage Adjustment Weight: Method

    During the second phase, a method known as raking ratio is used to adjust the weighting of each household so that the survey estimates agree with independent demographic estimates by sex and five-year age group. This method ensures that analyses at the level of individuals and households yield consistent results.

    Totals are calculated taking into account the probability of selection. The estimate is based on two types of a posteriori stratification, depending on whether the interviewees are employed or unemployed.
    To estimate the number of unemployed, a posteriori stratification is carried out by sex, age group and employment status according to the Register of Unemployment.
    To estimate the number of persons in employment, and those temporarily absent from work, a posteriori stratification of the sample and population is carried out by sex, age group and branch of activity. 147 strata are obtained this way.

    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 is carried out by administrative region and degree of urbanisation. Thus, each NUTS 2 region constitutes the first stratification level. Within each NUTS 2 region, communes and municipalities are stratified according to the Department (NUTS 3 region) to which they belong and the population of the main town. Saolnika and Athens are divided into 10 and 40 contiguous, well-defined sub-strata respectively.

    Weighting

    Design Weight: Target

    Household

    Design Weight: Method

    Inverse of selection probability

    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.

    Design Weight: Method

    Inverse of selection probability

    Non-response Weight: Method

    A posteriori stratification in two stages is applied, using independent demographic information. A linear weighting method in which each member of the household has the same weight is used. For a posteriori stratification are used: a detailed breakdown by age, sex, ethnic background, martial status and region.

    Coverage Adjustment Weight: Method

    Weights are benchmarked to the population totals without the institutional population.

    Design Weight: Method

    Inverse of selection probability

    Non-response Weight: Method

    For non-response adjustment the non-response correction factors are computed. The weighting 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.

    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). The subgroups by sex, age and the place of residence are considered. For this purpose, the Raking-Ratio method is applied. The calibration is based on the distribution of the Estonian population by sex, age and county as of 1st January of the survey year.
