Centre for Comparative Social Surveys

Welcome to the Centre for Comparative Social Surveys.

About the centre

The Centre for Comparative Social Surveys (CCSS) was established in 2003 and has since built a team of experts specialising in the design, implementation, and analysis of large scale and cross-national surveys. In addition, the CCSS experts engage in research on linking other data sources, e.g., administrative and geographical data to surveys. This includes technical solutions to anonymisation, micro simulations, and automatic coding.

The CCSS experts engage in research on linking other data sources, e.g., administrative and geographical data to surveys. This includes technical solutions to anonymisation, micro simulations, and automatic coding.  The CCSS host a variety of externally funded research projects investigating methodological and substantive issues in large scale and comparative surveys.

Among these projects are:

CCSS Projects

The Centre for Comparative Social Surveys (CCSS) is the headquarters of the European Social Survey (ESS), an academically driven cross-national survey of public attitudes and opinions carried out in more than 30 European countries.

Since 2013 the ESS has been established as a European Research Infrastructure Consortium (ERIC), cementing its place at the heart of European social science.

Carried out every two years,  the survey provides rigorous cross-national data on a wide range of topics including:

  • Political attitudes and engagement
  • Social norms and values
  • Religious and national identity
  • Socio-demographic background
  • Immigration
  • Work and family
  • Wellbeing
  • Crime and justice
  • Welfare policy

Data from ESS Rounds 1-7 are freely available to download via the project website.

Current research projects relating to the ESS:

Implementing ESS Rounds 8 and 9

CCSS staff are involved in all aspects of ESS survey design and implementation, helping to ensure that the survey is conducted to the highest methodological standards and remains at the forefront of comparative survey research. Preparations are well underway for Round 8 of the survey which will enter the field in September 2016. ESS Round 8 will include modules of questions on attitudes to welfare provision and energy use and climate change. A call for rotating module topics for ESS Round 9 (2018/19) has been issued.

Data from Round 7 of the survey (2014/15) are now available to download from the ESS website.

Synergies for Europe's Research Infrastructures in the Social Sciences (SERISS)

ESS ERIC is coordinating a major social science cluster project.   Funded by the European Commission under its Horizon 2020 programme, the €8.4m SERISS project (which runs until June 2019) aims to ensure that Europe’s social science data infrastructures are able to play an effective role in addressing the key challenges facing Europe today, as well as equipping national and European policy makers with a solid base of the highest-quality evidence on people’s attitudes, experiences and behaviour.

The ESS is working together with the Survey for Health Aging and Retirement in Europe (SHARE), the Consortium of European Social Science Data Archives (CESSDA),  the Generations and Gender Programme (GGP), European Values Study (EVS) and the WageIndicator Survey to address some of the key challenges facing cross-national data collection, break down barriers between research infrastructures and embrace the future of social science via new forms of data collection.


The ESS ERIC has secured a €2.3 million grant from the European Commission to help it increase the number of countries that take part in its research.  It is hoped that a significant increase in ESS membership will translate into lower costs of participation for the nations involved, while also strengthening the power of the survey’s datasets, and thus help to sustain the survey infrastructure.

ESS-SUSTAIN has the following key aims:

  • Enhancing the long-term commitment of existing members and observers of ESS ERIC
  • Transitioning countries with guest memberships to full member status
  • Expanding the coverage of the ESS to countries not yet affiliated
  • Fostering global links with other regional cross-national social surveys

The grant will support a number of activities including an impact case study in member countries, the appointment of ESS ambassadors to promote the study, investigation about accessing structural funds to finance membership and enhanced communications to highlight the output arising from the survey.


Rory Fitzgerald, Sarah Butt and Kaisa Lahtinen are involved in an ESRC-funded research project investigating the potential of auxiliary data to understand and correct for non-response bias in Round 6 of the ESS in the UK.

Making Well-being Count for Policy

Eric Harrison is working with colleagues from the New Economics Foundation and Cambridge University on an ESRC-funded project to build sustained public and political interest in the use of well-being data, and to explore where policy recommendations based on well-being data are possible.  The project uses ESS data on subjective wellbeing including items from the core questionnaire and the Round 3 and Round 6 rotating modules on Personal and Social Wellbeing.

European Social Survey Publications

The Centre for Comparative Social Surveys is home to the headquarters  of the European Social Survey  (ESS).

There are a number of  publications available that provide further information about the survey and contain analysis of the data.

In 2011, we launched a new series of ESS Topline Findings, which are concise cross-national summaries of particular topics covered in the questionnaire. Number 1 in the series focuses on trust in justice using data from Round 5 of the survey. Number 2 focuses on welfare attitudes in Europe using data from Round 4 of the survey. Number 3 focuses on the economic crisis, quality of work and social integration using data from Rounds 2 and 5 of the ESS. Number 4 focuses on Europeans' understandings and evaluations of democracy using data from Round 6 of the ESS and Number 5 focuses on dimensions of personal and social wellbeing, also using data from Round 6 of the survey.

This is a selection of key findings, both published and unpublished, using data from the first five rounds of the survey. This was released in July 2013.
