Individual and family characteristics that are affecting CIM include children's age, maturity and gender (Johansson, 2006), family structure, socioeconomic status, ethnicity (Loebach and Gilliland, 2014;Weir et al, 2006), gender of parent, and parent employment (Valentine, 2004;Witten et al, 2013). This includes matters regarding weight of school bags, convenience, families spending time together, and trip chaining (Johansson, 2006;O'Connor and Brown, 2013;Witten et al, 2013).…”
