ABOUT THE STUDY

The Labour Force Survey (LFS) is a large-scale, nationwide survey of households in Ireland conducted by the Central Statistics Office. It is designed to produce quarterly labour force estimates that include the official measure of employment and unemployment in the state (ILO basis). This survey replaced the Quarterly National Household Survey (QNHS) from Q3 2017. The QNHS began in September 1997, replacing the annual April Labour Force Survey (LFS).

Each quarter the LFS produces data among others on:

  • Numbers unemployed
  • Persons in employment
  • Labour force participation rates
  • Inactive population (not in the labour force)
  • Sectoral breakdown (Nace Rev. 2) of those in employment
  • Breakdown of headline data by age, sex and region
  • Persons in employment classified by occupation
  • Seasonally adjusted headline series
  • Data on family composition

 

MAIN TOPICS

  • Labour Market
  • Economic Activity
  • Employment History
  • Industries
  • Occupations
  • Status in Employment

 

COVERAGE, UNIVERSE, METHODOLOGY

Population

All households in the State.

Time dimension

Information is collected continuously throughout the year from households surveyed each week in each quarter. The reference quarters for survey results are: Q1 - January to March, Q2 - April to June, Q3 - July to September and Q4 - October to December. Households are surveyed in five successive quarters.

Geographical coverage

Country: Ireland

Methods of data collection

  • CAPI (Computer Aided Personal Interviewing)
  • CATI (Computer Aided Telephone Interviewing)

Sampling procedures

A new sample based on the 2011 Census of Population was selected for the LFS and this was introduced incrementally from Q1 2016. The sample is stratified using administrative county and the Pobal HP (Haase and Pratschke) Deprivation Index. A two-stage sample design is used. In the first stage 1,300 blocks are selected using Probability Proportional to Size (PPS) sampling. In the second stage households are selected using Simple Random Sampling (SRS). This ensures each household in the sample frame has an equal probability of selection.

To account for the additional attrition as a result of the introduction of mixed mode data collection, the LFS sample is being increased incrementally from Q3 2017. An additional 1,300 households are been included in Wave 1 for each quarter. As the sample is being increased by 1,300 households per Wave, the final design sample will increase to 32,500 households by Q3 2018.  The actual achieved sample varies over time depending on the level of response.

The number of valid responding households for the LFS in Q4 2017 was 13,419.

Households are asked to take part in the survey for five consecutive quarters and are then replaced by other households in the same block. Thus, one fifth of the households in the survey are replaced each quarter and the QNHS/LFS sample involves an overlap of 80% between consecutive quarters and 20% between the same quarter in consecutive years. It is important to note that there is no overlap in sample between the QNHS and the LFS.

The survey results are weighted to agree with population estimates broken down by age, sex and region and are also calibrated to nationality control totals. The LFS results also contain a non-response adjustment to make the results from the achieved sample representative of the target sample and the population. The population estimates for April of each year are published in a separate release.

New samples, both based on the 2011 Census of Population, were introduced incrementally for the QNHS in Q4 2012 and in Q3 2016. The former was stratified using administrative county and population density while the latter was stratified using administrative county and the Pobal HP (Haase and Pratschke) Deprivation Index. The quarterly sample in each case was 26,000 households. The actual achieved sample varied over time depending on the level of response.
