Annual Survey of Hours and Earnings linked to 2011 Census - England and Wales

This dataset links the Annual Survey of Hours and Earnings (ASHE) to the 2011 Census for England and Wales.

The Annual Survey of Hours and Earnings (ASHE), carried out in April each year, is the most comprehensive source of information on the structure and distribution of earnings in the UK. ASHE provides information about the levels, distribution and make-up of earnings and paid hours worked for employees in all industries and occupations. The census is undertaken by the Office for National Statistics every 10 years and gives us a picture of all the people and households in England and Wales.

Linking these datasets allows for insight into the dynamics of wage and employment issues, and how characteristics such as gender, disability, and ethnicity influence these. This linked dataset was developed as part of the Wage and Employment Dynamics project to aid better understanding of wage inequalities in Britain.

The Wage and Employment Dynamics team has also created some Stata code to enrich the core ASHE dataset and to add new variables such as minimum wage rates and survey dates. There are also new weights which account for attrition and selection effects, available from 2004. Access to the code will enable research into the dynamics of wage and employment issues, from labour market entry, through job mobility and career progression to retirement. It will be available within the Office for National Statistics (ONS) Secure Research Service on a shared accessible drive. Please note that this code is not part of the ONS ASHE official Statistics output.

Component datasets and linkage

This dataset is composed of the ASHE 2011 dataset which includes de-identified personal information such as age and gender, employment information such as wage and working hours and employer information such as the work postcode. ASHE has been linked to the 2011 Census which provides additional personal information such as education, qualifications, country of birth as well as family information.

Examples of research questions

  • How do people’s earnings change throughout their career? And how does this differ depending on characteristics such as gender, disability, or ethnicity?
  • What are the patterns or characteristics of those who do and do not progress out of low paid employment?
  • What is the relationship between migration and the labour market?
  • What role do employers play in wage inequality?

This list is illustrative only and intended to demonstrate the research potential of the dataset. For research priorities, see the areas of research interest or the ADR UK funding opportunity.

“This project addresses weaknesses in our evidence base – improving the quality of longitudinal earnings data and extending coverage to a broader range of characteristics –that should enable researchers to give new and innovative insights into the wage and employment dynamics of the lowest paid.”
