For ITV’s programme “Stephen Lawrence: Has Britain Changed?”, Number Cruncher conducted a poll of more than 3,000 UK adults, looking at experiences of, and attitudes towards racism in Britain.
The unusually large (1,502) subsample of ethnic minority respondents, which was weighted entirely independently of the white subsample, enables proper analysis of non-white Britons’ views.
Though Number Cruncher’s online methodology is naturally better suited than most to polling harder-to-reach demographic groups, for this poll we additionally included weighting by country of birth and individual ethnic group, in addition to the standard variables, in order to counter two of the traditional biases in polling of ethnic minorities.
The black subsample (405 unweighted) is of sufficient size to represent the views of the UK’s black community with a statistical margin of error of ±5 points.
Smaller crossbreaks, including for some individual ethnic groups, will have larger margins of error. Very small crossbreaks – notably the seven ethnic minority respondents in Northern Ireland – are included for completeness but are not statistically reliable.
A replay of the programme can be seen here (for those in the UK) or here. ITV’s Anushka Asthana (pictured) who presented the results on air, has provided her analysis here and British Future’s Sunder Katwala, who provided input to the ITV team, has written up his thoughts for CapX here.
On behalf of ITV, Number Cruncher Politics interviewed 3,065 adult (18+) UK residents online between 3rd and 12th July 2020. The sample included 1,563 white respondents and 1,502 ethnic minority respondents, of which 405 were black. White and ethnic minority subsamples were each independently weighted to the profiles of their respective subpopulations, from which nationally representative figures were derived based on the combined sample, weighted to representative proportions.
