Child Neglect: Background and Significance

Neglect is a special problem among younger children. Data suggest that children age 0-3 make up over half of all reported victims of medical neglect, and a third of all victims of other types of neglect. Such incidences of neglect may be more "invisible" for pre-school aged children than for older children since they need not come in contact with educators and medical professionals, who are best equipped to identify and report maltreatment. 

Neglect in these early years of life has serious consequences as pre-school children who have been neglected experience delays in language development and have lower IQ scores. Even mild or moderate levels of neglect, that do not rise to the level of being legally reportable, can have adverse consequences for pre-school children.
