Adulthood is usually defined as the period of human development in which the physical development, cognitive development, and psychosocial development of women and men slow and reach their highest level. Although scholars strive to build consistent theories, the description of the developmentally highest level differs between countries and cultures due to economic factors and sociocultural factors. After presenting some basic concepts of adulthood from different cultures, this entry continues with a psychological definition of adulthood, a discussion of characteristics of maturity, and brief descriptions of various theories about what constitutes adulthood. It ends with suggestions for the direction of future discussions on adulthood.

The approach to analysing population ageing and its impacts on the economy has evolved in recent years. There is increasing interest in the development and use of products and services related to gerontechnology as well as other social innovations that may be considered as central parts of the "silver economy." However, the concept of silver economy is still being formed and requires detailed research. This article proposes a typology of models of the silver economy in the European Union at the national and regional levels. This typology was created by comparing the Active Ageing Index to the typology of varieties and cultures of capitalism and typology of the welfare states. Practical recommendations for institutions of the EU and directions for further research are discussed.
