The purpose of this study is to examine the effects of cohabitation on children in kindergarten and how this varies by race. Many researchers have shown that children being raised in cohabiting families do not perform as well as children being raised in married parent families (Manning and Seltzer 2009; Artis 2007; Raley et al 2005). Furthermore, demographic trends show that cohabitation among Latinos is very similar to marriage, whereas among whites they are two very different things (Choi and Seltzer 2009). My research combines these two ideas to investigate how cohabitation may affect Latino children differently than it affects white children in terms of internalizing and externalizing behavior problems. I hypothesize that though whites will be negatively affected by cohabitation, Latinos will not have this negative effect. Evidence supports hypotheses and suggests that, indeed, Latino children are not as negatively affected by cohabitation as Whites.
