Multipartner fertility (MPF) and neighborhoods have been separate recent areas of investigation in the social sciences. This study attempts to understand the association between paternal multipartner fertility and child neighborhood disorder as measured by physical neighborhood disorder. These analyses use the most recent wave of the Fragile Families and Child Well-Being Study. I find that even after controlling for formal child support agreements and paternal sociodemographic characteristics, children whose fathers have children with multiple women live in neighborhoods with greater physical disorder than their peers whose fathers do not have MPF. I discuss the relationship between paternal MPF and child neighborhood disorder as well as potential future avenues of research in this area.
