Researchers from the DSI-NRF Centre of Excellence in Human Development at the University of Witwatersrand found that exposure to adversity in childhood can be linked to poor human capital in young adulthood. Human capital consists of the knowledge, skills, good health and education that people invest in and accumulate throughout their lives, enabling them to realise their potential as productive members of society. According to the research, the more adversity experienced, the greater the risk for negative outcomes such as criminality, psychological distress, unemployment and incomplete schooling in adulthood.
