Last updated: 27th June 2022

Base: Adults (16 and over)

Data collection paused in February 2020 among 16-17 year olds

Methods

Monthly household surveys of representative samples of 1700-1800 adults (16+ years old) in England

  • Due to the pandemic, from April 2020 to December 2021 surveys conducted by telephone (rather than face-to-face) and among adults aged 18 and over. From January 2022 data collection resumed among those aged 16 and over.
  • Between November 2020 and February 2022, ~0.8% of cases in England were incorrectly weighted 0. This has now been updated and some¬†point estimates over this period have changed slightly (typically 1 d.p.) compared with earlier versions.
  • From April 2020 (switch to telephone), Ipsos started recording ~<5% cases as missing for social grade. To derive weight variable (which uses social grade), Ipsos assumed missing = social grade C1. To ensure analyses using weight and social grade reflect target weighed profile, social grade was recoded to reflect this assumption. Different assumptions for missing social grade cases were explored in a parallel telephone and face-to-face (with no missing social grade) wave, and this assumption found least distorting.

Fieldwork by TNS/BMRB 2006 up to April 2013, then IPSOS MORI
