CSO statistical release, , 11am

Overview

This publication aims to provide insightful analysis in terms of employment and earnings among women in the labour market in Ireland, by combining a variety of labour market and earnings products, including the Labour Force Survey (LFS), Earnings Analysis Using Administrative Data Sources (EAADS), and Structure of Earnings Survey (SES).

Relevant CSO Publications

Labour Force Survey 

The employment component of this publication is based on the Labour Force Survey which is a continuous nationwide survey of households in Ireland, primarily designed to produce quarterly labour force estimates that include the official measures of employment and unemployment in the state in accordance with International Labour Organisation (ILO) concepts and definitions. 

The LFS replaced the Quarterly National Household Survey (QNHS) from Q3 2017. The original QNHS (re-labelled LFS) series from Q1 1998 to Q2 2017 has been adjusted to enable comparability with the new LFS for main headline indicators. The new LFS series is available from Q1 1998 to present.

Further information regarding methodology and definitions are available in the Background Notes of the publication.

Earnings Analysis Using Administrative Data Sources

The earnings component of this publication is based on the annual Earnings Analysis using Administrative Data Sources (EAADS) publication, which presents statistics on weekly and annual earnings based on administrative data sources, primarily Revenue’s employee tax data (PMOD). The estimates presented in EAADS are nominal earnings and are not adjusted for inflation. Please note that the earnings estimates presented in EAADS do not account for hours worked, or whether an employment was full-time or part-time.

Further information regarding methodology and definitions are available in the Background Notes of the publication.

Structure of Earnings Survey

The Structure of Earnings Survey (SES) is a nationwide survey of Irish employees conducted by the Central Statistics Office (CSO). The results of the SES 2022 presented in this publication relate to mean and median hourly earnings across the economy. Tables are provided by sector of activity, firm size, length of service, occupation, education, age and other factors that go towards explaining differences in rates of hourly pay. The survey covers both public and private sectors. The only excluded sectors are Agriculture, Forestry & Fishing. 

The purpose of the SES is to provide detailed structural information on earnings and factors influencing earnings. The SES is carried out on a four yearly basis and has been designed as an integrated survey that addresses issues of national interest while simultaneously fulfilling requirements under EU regulation (EC) No 530/1999.  Data on the structure of earnings has been provided to Eurostat for the reference years 2002, 2006, 2010, 2014 and 2018. However, the methodology over this time period has lacked consistency so comparisons between SES years are not directly comparable and should be interpreted with this in mind.

Further information regarding methodology and definitions are available in the Background Notes of the publication.
