The Annual Survey of Hours and Earnings (ASHE) is a UK wide survey that provides a wide range of information on earnings and hours worked. The Office for National Statistics (ONS) carries out ASHE in Great Britain and it is carried out by the Northern Ireland Statistics and Research Agency (NISRA) in Northern Ireland. ASHE replaced the New Earnings Survey (NES) from 2004, and ASHE comparisons are therefore only available on a consistent basis from that year onwards. The sample used comprises approximately 1% of all employees in Northern Ireland who were covered by Pay As You Earn (PAYE) schemes.
The survey information related to the pay-week (or other pay period if the employee was paid less frequently) which included 22nd April 2015, the reference date for the latest survey. The results are therefore not necessarily representative of pay over a longer period. They do not take account of subsequent changes in rates of pay which have become effective since April or changes which have been introduced with retrospective effect since the survey returns were completed.
Breach of the Code of Practice for Official Statistics
Just prior to the publication, an indication of the direction of change of weekly earnings for full time employees from the Annual Survey of Hours of Earnings 2016, was shared in error with officials not on the agreed pre-release access list, contrary to Protocol 2 Practice 8 of the code.
