An error has been identified in the Office for National Statistics (ONS) online time use survey (OTUS) data, which affects the following releases:

How people with a vaccine spent their time - one year on from the first UK lockdown: Great Britain, March 2021

A “new normal”? How people spent their time after the March 2020 coronavirus lockdown

Coronavirus and how people spent their time under lockdown: 28 March to 26 April 2020

Parenting in lockdown: Coronavirus and the effects on work-life balance

Homeworking hours, rewards and opportunities in the UK: 2011 to 2020

Recoding the raw data meant 10% of the weighted sample was dropped in error. The error was identified while we re-platformed our analysis system so that it was more automated. This includes improved embedded quality assurance, and as a result the risk of the error reoccurring is reduced. We will be updating weights to account for additional sources of bias (non-response bias) in the near future.

Although the new corrected data differs to that which is published, the key messages presented in the articles are unchanged. We will not be revising these with updated figures.
