ABOUT THE STUDY

The Labour Force Survey (LFS) replaced the Quarterly National Household Survey (QNHS) from Q3 2017. Similar to the QNHS, it is a large-scale, nationwide survey of households in Ireland. It is designed to produce quarterly labour force estimates that include the official measure of employment and unemployment in the state (International Labour Organisation classification).

 

MAIN TOPICS

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

 

COVERAGE, UNIVERSE, METHODOLOGY

Population

All individuals living in private households.

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.

Geographical coverage

Country: Ireland

Methods of data collection

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

Sampling procedures

A two-stage sample design is used. A new sample was introduced in Q4 2012 following the 2011 Census of Population and an additional new sample also based on the 2011 Census of Population will be introduced incrementally from Q3 2016. The sample frame of households is clustered into blocks (small areas) with each block containing a minimum of 60 occupied households on the night of the 2011 Census of Population. In the case of the sample introduced in 2012 the sample frame is stratified using administrative county and population density while the sample introduced in 2016 is stratified using administrative county and the Pobal HP (Haase and Pratschke) Deprivation Index. In the first stage 1,300 blocks are selected using Probability Proportional to Size (PPS) sampling and in the second stage 20 households are selected using Simple Random Sampling (SRS). This ensures that each household in the sample frame has an equal probability of selection and results in a total quarterly sample of 26,000 households. The actual achieved sample varies over time depending on the level of response.

The number of valid responding households in Q4 2016 was 15,808.

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 sample involves an overlap of 80% between consecutive quarters and 20% between the same quarter in consecutive years. As the new sample based on the 2011 Census of Population was introduced incrementally across each quarter from Q4 2012 to Q4 2013, the new sample is fully effective from Q4 2013.

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 population estimates for April of each year are published in a separate release.
