To understand what placement outside of one’s home means to the young people involved, we must understand foster care from a life course perspective. I analyze young people’s experiences in foster care from this perspective, accounting for when foster care happens, how long it lasts, and what happens when foster care placements end. I show that the population of children coming into foster care is younger and less urban than it was 20 years ago. I also show reliable measures of exposure to foster care over the life course. Children who enter care early in life are the children who spend the largest proportion of their childhood in foster care—a fact that rarely weighs on the policymaking process. We know very little about state and local variation in foster care placement rates, not to mention the influence of social services, the courts, foster parents, and caseworkers over foster children, so I close by arguing investment in research should be a clear policy priority.
