A central objective of the European Social Survey (ESS) is to improve the quality of cross-national survey design and implementation. This requires advances in the standards of survey methodology in many countries and advances in the conceptualisation and implementation of ideas of standardisation and comparability. In this paper, we will describe the procedures that were used to ensure equivalence of the sample designs used in the 23 countries participating in round 1 of the ESS. This involved the careful specification of the permissible parameters of the sample design as well as ongoing interaction between the ESS sampling panel and the ESS national co-ordinators in each country. A number of aspects of these procedures were novel and we will focus particularly on these and will attempt to evaluate the success of each. These include: Specification of the national sample size in terms of the “effective sample size” of interviews; Provision of guidance on how to predict the design effect due to variable selection probabilities ( P DEFF ) and the design effect due to clustering ( C DEFF ), and how to use these predictions to determine the necessary sample size; Intensive procedures for interaction between the members of the sampling panel, between the sampling panel and the national co-ordinators, and between the sampling panel and the ESS central co-ordinating team.
