Methodology

General Public: Quantitative Research

Ipsos interviewed a representative sample of 2000 adults per wave across the UK (England, Scotland, Wales and Northern Ireland) aged 18-75. All data was collected online via Ipsos online panel. Quotas were set on age, gender and region, to reflect the UK general population and data has been weighted to the population profile. Those who work in media, market research, PR or pharmaceuticals were screened out.

Fieldwork was conducted between the following dates:

1^st wave:	30^th June – 9^th July 2020
2^nd wave:	6^th – 13^th October 2020
3^rd wave:	13^th – 26^th January 2021
4^th wave:	18^th – 26^th March 2021
5^th wave:	23^rd September – 1^st October 2021
6^th wave:	18^th – 26^th January 2022
7^th wave:	16^th – 25^th March 2022
8^th wave:	18^th – 27^th May 2022
9^th wave:	13^th – 20^th April 2023

Where results do not sum to 100% or the ‘difference’ appears to be +/-1 more/less than the actual, this may be due to rounding, multiple responses, or the exclusion of don't knows or not stated responses.
