In the field of psychology and sociology, young adulthood is typically considered to be the period of development between adolescence and middle adulthood, roughly spanning from ages 18 to 30. This stage is characterized by major life transitions such as completing education, entering the workforce, forming intimate relationships, and starting a family. Researchers in this area often examine themes such as identity formation, independence, career development, mental health, and social relationships. Studies may investigate how individual differences and environmental factors influence the choices and experiences of young adults, as well as how these factors contribute to overall well-being and success during this stage of life.
