RT Journal Article SR Electronic T1 The Impact of Attrition on the Children of the NLSY79 JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 536 OP 563 DO 10.3368/jhr.XXXIX.2.536 VO XXXIX IS 2 A1 Aughinbaugh, Alison YR 2004 UL http://jhr.uwpress.org/content/XXXIX/2/536.abstract AB This paper examines the impact of attrition among the women of the National Longitudinal Survey of Youth 1979 (NLSY79) and children in the NLSY79 Mother-Child Supplement (NLSY79-C). Attrition among the children is nonrandom with respect to mother’s marital status, grandfather’s completed schooling, and family income. These differences that are related to the probability of attrition do not appear to impact estimates of the effects of family income or maternal employment early in the child’s life on either PPVT or BPI standard scores. However, the women who are not interviewed in any child-supplement year and the children for whom supplemental information is never collected appear to be the most disadvantaged. The omission of these children from the NLSY79-C may impact estimates of family characteristics on child outcomes, but because there are relatively few such children, the effects of their omission are likely to be small.
