NIS interpretations: Race and the National Incidence Studies of Child Abuse and Neglect

The National Incidence Studies (NIS) of Child Abuse and Neglect are the primary estimates of actual child maltreatment rates in the United States. Findings from the NIS-2 of 1986, and the NIS-3, of 1993, have been presented as demonstrating that Blacks and Whites are maltreated at equal rates. The NIS-4, using 2006 data, was presented as showing markedly different findings from the prior NIS studies with regard to race. A supplementary NIS-4 report on race argued that differences between the NIS-3 and NIS-4 were due to better precision and an expanding income gap between Blacks and Whites between 1993 and 2006. This paper will demonstrate that the NIS-2 and NIS-3 did not, as is commonly believed, show equivalence between Black and White maltreatment rates and that the NIS-2, NIS-3 and NIS-4 do not differ markedly in their racial findings. Further, the large historical increase in the Black/White income gap cited in the NIS-4 race supplement derives from a simple failure to account for inflation. If left unaddressed, misinterpretations of NIS data will continue to misinform policy, cloud the issue of racial bias in the child welfare system and obscure the ongoing role of concentrated poverty in driving racial disproportionality.
