tasks. During emerging adulthood friendships sometimes will be more important than your family relationships. Shulman (1975) found that when emerging adults (18–30) were asked who was in their personal networks 41% were more likely to put down friends instead of family members. Emerging adults have reported that they have less positive feelings with their siblings, but have positive feelings with their friends. There was a study done on single emerging adults, that reported their most preferred companions were friends, especially if the emerging adult has no partner and no longer fully relies on their parents. Gender Differences Several changes occur throughout adolescence and emerging adulthood. Adolescents begin to learn and use coping strategies in order to navigate the choices and crises of emerging adulthood. During emerging adulthood, males and females both use problem-solving oriented coping most often. Males take a more passive approach to coping with the choices and adjustments of emerging adulthood, and females take on a more active approach. Females are more focused on quickly learning and adapting to adulthood. Male's success or their failure determined the negative life events that they would experience later. This could be attributed to the pressure they feel to provide. Men feel more pressure to succeed in academic ways and create a successful life whereas women feel more of a pull towards family and children. Culture Of the world population in 2016 (7.5 billion), 6.1 billion people, or 80%, lived in developing economies. Demographers distinguish between developing countries and the economically advanced, industrialized nations that form the Organisation for Economic Co-operation and Development (OECD). This includes countries and regions like the United States, Canada, Western Europe, Japan, South Korea, and Australia, all of which have significantly higher median incomes and educational attainment and significantly lower rates of illness, disease, and early death. The theory of emerging adulthood is specifically applicable to cultures within these OECD nations, and as a stage of development has only emerged over the past half century. It is specific to "certain cultural-demographic conditions, specifically widespread education and training beyond secondary school and entry into marriage and parenthood in the early or late thirties or beyond." Furthermore, emerging adulthood occurs only within societies that allow for occupational shifts, with emerging adults often experiencing frequent job changes before settling on a particular job by the age of 30. Arnett also argues that emerging adulthood happens in cultures that allow for
