Σύνοψη	The Post-Materialism Index, developed by Ronald Inglehart (1971), classifies individuals as materialist, postmaterialist, or mixed based on the priority they assign to physical and economic security versus self-expression, belonging, and quality of life. It operationalizes Inglehart's silent-revolution thesis that prosperity and security in postwar democracies caused an intergenerational shift from materialist to postmaterialist value priorities.	The Schwartz Value Survey (SVS) operationalizes Schwartz's (1992) theory of basic human values, which identifies ten (later refined to nineteen) motivationally distinct values organized in a circular structure along two axes: openness to change versus conservation, and self-enhancement versus self-transcendence. It is the most widely used cross-cultural values instrument and underlies much research on the value basis of political ideology.
