We identified a weighting issue on our Opinions and Lifestyle Survey which resulted in some distributions of population totals presented in the September 2022 to October 2022 dataset not matching official population estimates published by ONS. This is limited to analysis based on pooling a number of waves of OPN data together.

This issue occurred because of a processing error and should not impact any future analysis.

This issue does not appear to affect rounded estimates or messages provided in the release or datasets. However, weighted population counts that are provided in these datasets should not be used. We apologise for any inconvenience caused.
