Background and Aims Questions about drinking ‘yesterday’ have been used to correct under‐reporting of typical alcohol consumption in surveys. We use this method to explore patterns of over‐ and under‐reporting of drinking quantity and frequency by population subgroups in four countries. Design Multivariate linear regression analyses comparing estimates of typical quantity and frequency of alcohol consumption with and without adjustments using the yesterday method. Setting and Participants Survey respondents in Australia (n = 26 648), Canada (n = 43 371), USA (n = 7969) and England (n = 8610). Measurements Estimates of typical drinking quantities and frequencies over the past year plus quantity of alcohol consumed the previous day. Findings Typical frequency was underestimated by less frequent drinkers in each country. For example, after adjustment for design effects and age, Australian males self‐reporting drinking ‘less than once a month’ were estimated to have in fact drunk an average of 14.70 (± 0.59) days in the past year compared with the standard assumption of 6 days (t = 50.5, P
