A number of factors may impact on alcohol consumption data and contribute to the different results reports in the Health Survey for England and Understanding Society.
Mode of data collection
- Evidence suggests that data collected by self-completion gives higher estimates of alcohol consumption than in a face-to-face interview.
- The alcohol consumption questions used on HSE and Understanding Society differ which may impact on reported levels of consumption.
Calculation of alcohol units
- Detailed questions on HSE permit more precise conversion of alcohol type and volume to alcohol units.
- Understanding Society covers a wide range of topics whereas HSE is specifically about health – this may affect respondents’ willingness to report high levels of alcohol consumption.
- However, the evidence from the Opinions and Lifestyle Survey suggests this is not the case.
- Understanding Society and HSE have different sampling and weighting methodologies which could impact on the alcohol consumption estimates.
