Emerging adulthood and early adulthood: Emerging adulthood is a phase of the life span between adolescence and full-fledged adulthood which encompasses late adolescence and early adulthood, proposed by Jeffrey Arnett in a 2000 article in the "American Psychologist".  It primarily describes people living in developed countries, but it is also experienced by young people in urban wealthy families in the Global South.  The term describes young adults who do not have children, do not live in their own home, or do not have sufficient income to become fully independent in their early to late 20s.  Arnett suggests emerging adulthood is the distinct period between 18 and 25 years of age where adolescents become more independent and explore various life possibilities.  Arnett argues that this developmental period can be isolated from adolescence and young adulthood.  Emerging adulthood is a new demographic, is contentiously changing, and some believe that twenty-somethings have always struggled with "identity exploration, instability, self-focus, and feeling in-between".  Arnett called this period "roleless role" because emerging adults do a wide variety of activities and not constrained by any sort of "role requirements"."  The developmental theory is highly controversial within the developmental field, with developmental psychologists contested over the legitimacy of Arnett's theories and methods.
