marked as ‘Chk’) also caused break offs (38 per cent of addresses with an incomplete household grid). These results are in contrast with Test 1, when a larger proportion of break-offs occurred at the first question about the respondent’s name (61 per cent). A summary of break-off points for Tranche 1 is provided in table 15 below: Table 15: Table showing point of break-off for incomplete Household Grid responses Question Number % Person1 126 42.4 Person2 16 5.4 Person3 11 3.7 Person2Chk 103 34.7 Person3Chk 11 3.7 Other 37 10.1 297 100.0 Within the individual section of the questionnaire, 749 individuals broke off their response without completing it. The most common breakoff point was the date of birth question (S3_1_1) with 177 respondents (24 per cent of breakoffs). This was in line with the findings from Test 1. At an individual-level, the majority of respondents (96 per cent) completed their questions in one sitting. 830 individuals restarted the survey after logging off or allowing the questions to time out half way through. Split sample experiment for ethnicity question Within the script, we conducted a split sample experiment whereby one half of the sample was allocated to one version of the main ethnicity question and the other half were presented with a different version. Version 1 included ‘Chinese’ at code 3 and not at code 5. For version 2, Chinese was included at the other option, code 5 as opposed to code 3. The two questions, their code lists and the breakdown of responses are presented below and these show that respondents were more likely to code ‘Other’ when Chinese was listed in the examples than if not (1.5 per cent compared with 0.7 per cent in the scenario without ‘Chinese’ as an example in the ‘Other’ option). 16: Table showing response breakdown for version 1 of QETHNICITY Question Number % Includes any White background 9,556 91 Mixed or multiple ethnic groups: Includes White and 197 1.9 Black Caribbean, White and Black African Asian or Asian British: Includes Indian, Pakistani, 498 4.7 Bangladeshi, Chinese or any other Asian background African, Caribbean or Black British: Includes African, 180 1.7 Caribbean or any other Black background Other: For example Arab or any other background 70 0.7 TOTAL 9,556 100.0
