Who collects data on the Family Food Experience - London survey?

The Family Food Experience survey helps to build a picture of food environments and children’s eating habits among families with primary school aged children.

The survey is a collaboration between NatCen Social Research (NatCen) and City, University of London. City, University of London is the data controller for the Family Food Experience survey. NatCen is responsible for collecting the data on the Family Food Experience survey and is the data processor on the survey, processing the data collected so that it can be used for research, while ensuring that it will not be possible to identify any participants in the data.

Do I have to take part?

Taking part in the Family Food Experience survey is completely voluntary. You have the right to stop being part of the survey at any time without giving a reason.

What will happen to any information I give?

We will treat your information in the strictest confidence under current data protection legislation. Under this legislation (Article 6), we process your information on the basis of ‘legitimate interest’ because our research aims to help build a picture of how local authorities in London can improve the efficiency and effectiveness of interventions to address inequality in childhood obesity.

The results are used for research and statistical purposes only. All survey findings are anonymised, which means that it will not be possible to identify any participants from the published results.

Your personal details are held by and stored securely by the team who administer and process the results of the survey at NatCen. All information you provide to us is stored on our secure servers, in line with international best practice and NatCen’s ISO27001, ISO 20252 and Cyber Essentials Plus certifications. We have a comprehensive set of policies and procedures to prevent unauthorised access which apply to all parts of NatCen, and alongside our ongoing programme of internal audits we undergo formal external audits every 6 months to ensure we continue to meet all the requirements of ISO27001 and other international best practices.

Your details will never be passed on to anyone else without your permission, with the exception of one security-checked organisation directly working with us to administer the survey: the printers (who print the letters we send to you). This organisation is from NatCen’s Approved Supplier List and have been vetted by us, with signed contracts and agreements (refreshed every 12 months), to ensure that strict data security arrangements are followed.

Your information will be kept for at least 10 years. You have the right to request access to your data, to amend them if they are incorrect, or that your data are deleted. Please note that once your anonymised data has been finalised and combined with that of others, it cannot be deleted. This is because this data may already form part of the data in publications.

You can request that your identifiable data is deleted at any time. To do this, please get in touch with NatCen using the contact details provided on this website.

In the future, City, University of London may want to contact you to invite you to take part in another study. We will only do this if you consent to this during your Family Food Experience interview. If you are invited to take part in any future studies, you will be free to refuse if you do not want to take part.
