College Completion Among Young Adults With a Disabled Sibling

Twelve percent of families in the United States have a child with a disability, yet little is known about the long-term consequences of growing up with a disabled sibling. This study builds on previous research regarding disability effects on families and offers an additional view on the linked lives of families and, in particular, siblings. Using secondary data from the National Longitudinal Survey of Youth 1979 Children and Young Adults, this study examines the odds of college completion among young adults with a disabled sibling during childhood. Specifically, I examine the gender differences among those who had a sibling with a disability. Women are more than 35% less likely to complete college if they had a disabled sibling during childhood; there is no significant difference by sibling disability status for boys. To understand whether children in low-resourced families are particularly penalized by having a disabled sibling, I examine whether various family resources attenuate the low graduation odds among those who had a disabled sibling. I find that having stably married parents during childhood largely eliminates the college completion gap between those with and without a disabled sibling. However, increases in mothers' education or family income do not attenuate the college completion gap. By identifying this gender disadvantage in college completion, this study shows that disabilities have consequences not just for disabled individuals but for their siblings as well, shining a light on a hidden cost of disability on families.
