Thank you for your query regarding night workers in Yorkshire and The Humber.

Information on night working is collected on the Labour Force Survey, however we do not regularly produce any outputs using this variable. Therefore the requested information is not readily available from published outputs.

Although we do not produce regular analysis on night workers, you can request an ad-hoc analysis be produced to give this detailed information from our Social Surveys Division. Information on how to make such a request are given on our website.

As explained on the website, such ad-hoc analysis requests may incur a charge;
