The European Values Study is a large-scale, cross-national, and longitudinal survey research program on basic human values, initiated by the European Value Systems Study Group (EVSSG) in the late 1970s, at that time an informal grouping of academics. Now, it is carried on in the setting of a foundation, using the (abbreviated) name of the group European Values Study (EVS).

The World Values Survey is a worldwide investigation of sociocultural and political change collecting comparative data on values and belief systems among people around the world. WVS builds on the European Values Surveys, first carried out in 1981. A second wave of surveys, designed for global use, was completed in 1990-1991, a third wave was carried out in 1995-1996 and a fourth wave of surveys is being carried out jointly by the EVS and WVS groups, in 1999-2001.
Data from the fourth wave is not yet generally available for academic use.

The Global Barometer Surveys is an umbrella consept that refers to similar data collections in different parts of the world, the Afro-barometer LatinoBarometer, East Asia Baromer or The New Europe Barometers.

Other African survey data are available from the World Bank
