In Table 1 below Column A lists the data already integrated in the Survey Data Harmonization project. Column B shows the expansion – in terms of projects and project-waves – that the SDR project will undertake.

European Values Study (EVS) examines social, political and economic values and attitudes, as well as life conditions, in most European countries. The surveys are carried out every nine years since 1981, and each consecutive wave includes more national samples. EVS and WVS coordinate to include similar question items, and datasets from both survey projects can be combined and used together.

International Social Justice Project (ISJP) is an international collaborative survey project focused on popular beliefs and attitudes on social, economic and political justice. Two large-scale opinion surveys were fielded in all twelve countries in 1991 and in six countries in 1996. In 2000 a second replication was carried out in Germany, and in 2006 in Germany and in other countries replicating the ISJP (Israel, Chile, Czech Republic and Hungary).

International Social Survey Program (ISSP) is a continuous program of cross-national collaboration running annual surveys on topics important for the social sciences. It covers a wide range of issues which relate to social structure, including political attitudes, values, data about education and occupation of respondents.

New Baltic Barometer (NBB) was launched in 1993 to reflect opinions in three multi-ethnic societies, Estonia, Latvia and Lithuania, incorporated into the Soviet Union as a consequence of the Second World War.

Five NDB surveys were conducted between 1991 and 1998. Changes in Europe have been matched by changes in the New Europe Barometer survey. After the fifth round, the CSPP took responsibility for conducting surveys of post-Communist countries seeking membership in the European Union. It has conducted NEB rounds in 2001 and the winter of 2004/5.

Political Action II (PA2) is a replication of Political Action: An Eight Nation Study (PA8NS), and was carried out between 1979 and 1981 to study satisfaction with material standard of living, interest in politics, perception of privileged and under-privileged groups, opinions on various social and political issues, and ranking of important political goals.
