THE EDUCATIONAL BENEFITS OF BEING SPACED OUT - SIBSHIP DENSITY AND EDUCATIONAL-PROGRESS

Although sociologists have identified factors associated with the timi ng of births, little is known about the consequences of the spacing of births. Several perspectives imply a negative effect of close spacing of siblings on educational attainment, but these perspectives differ in the mechanisms used to explain this effect. We use data from the Hi gh School and Beyond survey to investigate the effect of spacing on hi gh school attrition and post-secondary school attendance. Our analysis confirms that close spacing increases the likelihood of dropping out of high school and decreases the odds of attending post-secondary scho ol. The direct effect of close spacing on post-secondary school attend ance persists net of ability and academic performance; the effect of s pacing on dropping out of high school is mixed. Close spacing of sibli ngs also constrains the allocation of family resources, which in turn affects educational attainment. Alternative explanations of the relati onship between sibship structure and educational outcomes are reinterp reted in light of these findings.
