Chapter 2 describes a process of intergenerational change linked with rising levels of existential security occurring across countries. Using representative national surveys carried out almost every year in six West European countries, Chapter 2 documents that a move from older to younger cohorts is linked to gradual shifts toward a diminishing proportion of Materialists and a growing proportion of Postmaterialists. This chapter also finds that the younger cohorts remain relatively Postmaterialist over time, implying that as the younger cohorts replace the older, the society’s prevailing values will change. Chapter 2 argues that the logic of the Postmaterialist shift has significant implications for other countries as well and predicts that the shift from Materialist to Postmaterialist values will be spreading to many other countries. While Postmaterialists constitute tiny minorities in many developing countries, such as China and India, if they continue on their present trajectories, a shift toward Postmaterialist values will take place when a younger generation emerges that has grown up taking survival for granted.
