This research investigates the factors conducive to the success of young people growing up in low-income families. Many studies carried out locally and overseas focus on the risks and difficulties experienced by these young people; however, little attempt has been made to examine the factors that help them change their lives from failure, poverty, and social exclusion. Based on a quantitative survey of 405 young people recruited from schools and integrated youth service centers in Hong Kong, this research identifies a range of indicators of, and necessary conditions for, the positive development of young people with economic disadvantage. It also evaluates the way in which the functions of service participation, friendship networks, and various family factors support them to thrive in different areas. The study helps fill the gap of the existing literature and draws implications for policy and practice to address the needs of these youths. Future directions of research are also discussed.
