Important points about ASHE data

  • ASHE provides a snapshot of earnings information in the UK at the survey reference date in April each year.
  • Various breakdowns of ASHE estimates are available, including industries, occupations, geographies and age groups.
  • ASHE analyses for weekly and hourly earnings relate to employees on adult rates whose earnings for the survey pay period were not affected by absence.
  • ASHE analyses for annual earnings relate to employees on adult rates of pay who have been in the same job for more than 1 year.
  • ASHE does not cover the self-employed or employees not paid during the reference period.
  • The quality of some estimates at low levels of disaggregation can be poor and these domains are more susceptible to larger revisions.
  • Changes to ASHE methodology resulted in breaks in the series in 2004, 2006 and 2011.
  • ASHE is not directly comparable with the Average Weekly Earnings (AWE) or the Labour Force Survey (LFS), details can be found under the coherence and comparability section in the QMI.

Overview

ASHE is the most comprehensive source of earnings information in the UK. It provides information about the levels, distribution and make-up of earnings and hours paid for employees by sex and full-time and part-time working. Estimates are available for various breakdowns, including industries, occupations, geographies and age groups. ASHE is used to produce hours and earnings statistics for a range of weekly, annual and hourly measures.

ASHE is based on a 1% sample of employee jobs taken from HM Revenue and Customs (HMRC) Pay As You Earn (PAYE) records. Information on earnings and hours is obtained from employers and treated confidentially.

ASHE is the official source of estimates for the number of jobs paid below the National Minimum Wage. ASHE is also used to produce estimates of the proportion of jobs within each workplace pension category.

Given the survey reference date in April, the survey does not fully cover certain types of seasonal work, for example employees taken on for only summer or winter work.
