I would like to know if you have data on loneliness in older people by region, particularly relating to the ‘proportion of people who report feeling lonely in their daily life by age group, 2014 to 2015. Source: Opinions and Lifestyle Survey (OPN) - Office for National Statistics

Thank you for your request. The requested information in the format required is not held by the Office for National Statistics (ONS). We are unable to provide the data from the 'proportion of people who report feeling lonely in their daily life by age group, 2014 to 2015' figure, at a regional level from the Opinions and Lifestyle Survey because of the small size of the sample. It would be statistically unreliable but also it might be possible to identify individuals and their responses to the question as some cells would contain only one or two cases. The information would then be exempt from disclosure under s.40 of the Freedom of Information Act as it would constitute personal data and also s.41 information provided in confidence.
