Response to the survey
Address-level response rates
Table A.1: (Address-level response) summarises the address-level response rates.
In total, 18,778 addresses were issued. In remote surveys (that is where participants complete the survey independently without any involvement from an interviewer), no information is known about the reason for non-response in individual addresses. However, it was assumed that around 9 percent of addresses in the sample (1,690) were not residential and were therefore ineligible to complete the survey1.
In total, 3,181 addresses were productive. The adjusted address-level response rate, that is the proportion of eligible addresses where a questionnaire was completed by at least one adult, was 19 percent (lower than the target of 22 percent). There was no response from 13,893 addresses and a further 14 addresses had an individual contact the office to say they did not wish or were unable to take part.
Table A.1: Address-level response rates
| Response of issued addresses | Total addresses (number) | Total addresses (percentage) | Total eligible (percentage) |
|---|---|---|---|
| Issued addresses | 18,778 | 100% | Not applicable |
| Assumed ineligible | 1,690 | 9% | Not applicable |
| Assumed eligible (residential addresses) | 17,088 | 91% | 100% |
| Refusal or unable to take part | 14 | 0% | 0% |
| No response | 13,893 | 74% | 81% |
| Productive addresses | 3,181 | 17% | 19% |
Table A.2: (Address-level response, by country and Government Office Region) shows the breakdown of the issued sample in England, Scotland, and Wales, and English regions and the household response rate in each country and region. In total, 86 percent of the issued addresses were in England, 9 percent in Scotland and 5 percent in Wales. Household response rate was 19 percent in England and Scotland and 17 percent in Wales. In English regions2, the highest response rates were achieved in the South West (24 percent) and South East (21 percent) and the lowest in London (15 percent).

| Country/Government office region | Total issued addresses (number) | Total issued addresses (percentage) | Total assumed eligible addresses (number) | Total assumed eligible addresses (percentage) | Total productive addresses (number) | Household response rate (percentage) |
|---|---|---|---|---|---|---|
| England | 16,110 | 86% | 14,660 | 86% | 2,737 | 19% |
| North East | 812 | 4% | 739 | 4% | 125 | 17% |

Individual-level response rates
Following the process of removing duplicate responses3, cases deemed to have completed the online questionnaire too quickly to have properly engaged with the questions and cases above the maximum 2 completions per household4, it was assumed that all responses in the dataset were from 4,657 unique individuals who had completed the questionnaire.
In total, 45 percent of the responding unweighted sample were male, and 55 percent were female, as shown in Table A.3: (Individual-level response, by sex and age). This under-representation of males is similar to that seen in the latest published results for other surveys with the same completion modes, for example, the British Social Attitudes (BSA) 2022 survey - BSA 40 Technical details (natcen.ac.uk) (opens in new tab)(pdf). In total, 44 percent of the BSA 2022 unweighted main sample were male and 56 percent female.
Those in the youngest age group were the least likely to take part: 6 percent of responding adults were aged 18 to 24, whereas this age group makes up 10 percent of the adult population of Great Britain. Conversely, 18 percent of responding adults were aged 65 to 74, whereas this group makes up 12 percent of the population. (Table A.3: Individual-level response, by age and sex).
This difference in taking part was particularly pronounced for male participants: 5 percent of the male sample were aged 18 to 24 years (this age-sex group makes up 11 percent of the male adult population of Great Britain). The equivalent proportions for females aged 18 to 24 years were 7 percent and 11 percent. The national percentages are based on the 2022 mid-year population estimates for Great Britain: Estimates of the population for the UK, England, Wales, Scotland and Northern Ireland by the Office for National Statistics (ONS) (opens in a new tab).
Table A.3: Individual-level response, by sex and age
| Age group (years) | Total participants: male (percentage) | Total participants: female (percentage) | Total participants: all (percentage) | Total Great Britain population: adult males (percentage) | Total Great Britain population: adult females (percentage) | Total Great Britain population: all adults (percentage) |
|---|---|---|---|---|---|---|
| 18 to 24 | 5% | 7% | 6% | 11% | 11% | 10% | 25 to 34 | 13% | 17% | 15% | 17% | 17% | 17% | 35 to 44 | 15% | 17% | 16% | 17% | 17% | 16% | 45 to 54 | 15% | 14% | 14% | 16% | 16% | 16% | 55 to 64 | 18% | 19% | 19% | 16% | 16% | 16% | 65 to 74 | 21% | 15% | 18% | 12% | 12% | 12% | 75 plus | 13% | 11% | 12% | 10% | 10% | 11% | All participants | 45% | 55% | 100% | 48% | 48% | 100% | Unweighted bases (number) | 2,085 | 2,564 | 4,649 | 25,243,097 | 26,929,894 | 52,172,991 |
Table A.4: (Individual response, by mode of completion and sex) shows response rates by mode of completion, overall and for males and females separately. Overall, 63 percent (2,918) completed the survey online and 37 percent (1,732) completed a postal questionnaire. These results are broadly in line with expectations, based on the development stages of the GSGB.
Table A.4: Individual-level response, by mode of completion and sex
| Sex | Individual-level response: Online completions (percentage) | Individual-level response: Postal completions (percentage) | Individual-level response: Total completions (percentage) | Individual-level response: Total completions (number) |
|---|---|---|---|---|
| Males | 64% | 36% | 45% | 2,085 |
| Females | 62% | 38% | 55% | 2,565 |
| All participants | 63% | 37% | 100% | 4,650 |
| Unweighted bases (number) | 2,918 | 1,732 | 4,650 | 4,650 |
There was little difference between males and females in the mode of completion. In all age groups, except the oldest two (aged 65 to 74 and aged 75 and over), a higher proportion of participants completed the survey online than filled in the postal questionnaire. In total, 48 percent of those aged 65 to 74 and 28 percent of those aged 75 and over completed the survey online compared with between 53 percent and 85 percent of those in the younger age groups as shown in Table A.5: (Individual-level response, by mode of completion and age).
Table A.5: Individual-level response, by mode of completion and age
| Age group (years) | Individual-level response: Online completions (percentage) | Individual-level response: Postal completions (percentage) | Individual-level response: Total completions (number) |
|---|---|---|---|
| 18 to 24 | 84% | 16% | 289 |
| 25 to 34 | 85% | 15% | 690 |
| 35 to 44 | 81% | 19% | 732 |
| 45 to 54 | 72% | 28% | 676 |
| 55 to 64 | 53% | 47% | 876 |
| 65 to 74 | 48% | 52% | 834 |
| 75 plus | 28% | 72% | 559 |
| All participants | 63% | 37% | 4,656 |
| Unweighted bases (number) | 2,922 | 1,734 | 4,656 |
The mode of survey completion was similar for those who participated in gambling in the past 4 weeks and those who did not, with 64 percent of those who participated in gambling in the past 4 weeks completing the survey online and 63 percent of those who did not, as shown in Table A.6: (Individual-level response, by mode of completion and gambling participation in the past 4 weeks).

| Gambling prevalence in the past 4 weeks | Individual-level response: Online completions (percentage) | Individual-level response: Postal completions (percentage) | Individual-level response: Total completions (number) |
|---|---|---|---|
| Gambled in the past 4 weeks | 64% | 36% | 2,160 |
| Not gambled in the past 4 weeks | 63% | 37% | 2,435 |
| Unweighted bases (number) | 2,920 | 1,675 | 4,595 |

1When estimating the proportion of ineligible addresses on an online survey, it is best practice to assume the same ineligibility rate as a recent face-to-face survey which uses the same sample frame and sampling approach and for which detailed outcomes are known for the entire issued sample. Ineligibility rates in Postcode Address File (PAF) face-to-face surveys tend to fall between 8 percent and 10 percent and 9 percent is the rate recorded in the most recent face-to-face British Social Attitudes Survey (2019) and so has been used as an appropriate default for this survey.
