Advances in Cross-National Comparison 
A European Working Book for Demographic and Socio-Economic Variables

As the European Union grows together we are faced with an increasing number of European surveys and statistics that rely on national instruments or questionnaires. We lack valid instruments with functional equivalence that allow international comparative analysis. This problem is especially important in the case of demographic and socio-economic variables. The usual practice in comparative social research is to work with national questionnaires and classifications thereby making meaningful comparisons questionable. To overcome these problems this book offers rules of comparison, tested instruments and examples for the measurements of basic demographic and socio-economic variables.The book consists of five parts and a concluding chapter. Part 1 covers general problems and presents solutions for the harmonisation of data from different national and/or cultural contexts. In the second part EUROSTAT and ESOMAR present their established standard instruments. Tested instruments each covering one variable (i.e. occupation, education) are presented in the third part. The fourth part again includes suggested tools for the harmonisation of single variables for which standardised instruments are not yet available (i.e. age, religion, ethnicity, household, family, income). The last part presents selected empirical analyses demonstrating the use and fruitfulness of instruments presented before.This book is mainly written for two groups. First, researchers and practitioners involved in comparative research in Europe. Second, researchers working with data of the statistical offices of European countries and data from institutions of the European Union.
