Face-to-face surveys of the general population often start with a probability sample of the households or addresses. However, even if a probability sample of households or addresses has been drawn, random selection of the target respondent within the selected household is crucial for obtaining a probability sample of individuals comprising the population. Over a dozen procedures of within-household selection have been described in survey literature. This article is concerned only with the two most popular of these, i.e., with the Kish grid procedure and the class of birthday procedures (i.e., next-birthday, last-birthday and closestbirthday methods). The main goal of this paper is to address the question of whether the Kish grid and birthday methods differ in their impact on: (1) refusal and cooperation rates, and (2) demographic representation of the survey sample, as well as (3) the degree of interviewers' infl uence on the selection process. Based on 98 different surveys from all seven rounds of the European Social Survey, a meta-analysis was conducted to generate quantitative measures indicating the size of the overall impact of Kish grid and birthday procedures. Several conclusions can be formulated based on the analysis. Firstly, Kish grid samples (compared to birthday samples) result in signifi cantly higher odds of receiving refusals and signifi cantly lower odds of obtaining cooperation. Secondly, both Kish grid and birthday samples have a similar and signifi cant impact on gender and age imbalance. Finally, birthday procedures give interviewers greater opportunity to infl uence the selection process. The latter means that the use of Kish grid samples is usually associated with a higher quality of the within-household selection, even though in such samples refusal rates are signifi cantly higher and cooperation rates are signifi cantly lower compared to those obtained in birthday samples.
