​Please could you indicate where I can find a dataset that includes the most popular UK names per UK social class, preferably of the latest year.

We said

Thank you for your enquiry.

We are responsible for publishing baby names statistics for births registered in England and Wales. The most recent year for which data are available is 2018. Data relating to baby names for 2019 will be published in August 2020.

For detailed information on baby names statistics for 2018 please see our boys' baby names and  girls' baby names datasets. They provide statistics on rank and count of the top baby names, changes in rank since the previous year and breakdown by country, region and month of birth. We also publish Baby names in England and Wales bulletin with commentary regarding the above datasets.  

We do not publish baby names by socio-economic class, as NS-SEC codes are assigned to only 10% of our birth records. However, we may be able to produce a bespoke request using this limited amount of data. Any such analysis would be outside of the Freedom of Information regime and would be subject to legal frameworks, disclosure control, resources and agreement of costs where appropriate. If this is something you would be interested in, please contact Health.Data@ons.gov.uk  so that we can discuss your enquiry further. For more information about the services we offer please visit our website.
