Educational attainment is known to be related to family size, birth order, and the educational achievement of an older sibling.
This study examines younger siblings in large families, exploring the extent to which each older sibling's educational attainment is associated with attainment of the younger sibling.
Linkable administrative data were used to create a population-based cohort of third children in three child families born in Manitoba, Canada between April 1, 1984 and March 31, 1994, who stayed in the province until at least age 20 (n = 5,771). Logistic regression models were used to examine the relationship between the youngest siblings' educational achievement and that of their older two siblings, adjusting for a series of confounders.
Youngest siblings have the greatest odds of graduating from high school if both older siblings graduated. Females also had greater odds of graduating if only one of those older siblings had graduated; this did not increase the odds for males. Associations in educational attainment were stronger when siblings were born close together. For siblings born further apart, these associations were stronger if those siblings were of the same sex as the youngest sibling.
In large families, the educational attainment of each older sibling is associated with the educational attainment of the younger sibling; associations differ depending on the birth order and sex of the older siblings. Families in which older siblings do not graduate from high school may be experiencing numerous challenges. Children with older siblings who fail to graduate may benefit from additional supports to increase their likelihood of graduation.
已知受教育程度与家庭规模、出生顺序以及年长同胞的教育成就有关。
本研究对大家庭中的年幼同胞进行考察，探究每位年长同胞的受教育程度与年幼同胞受教育程度的关联程度。
利用可关联的行政数据，建立了一个基于人群的队列，该队列由1984年4月1日至1994年3月31日在加拿大曼尼托巴省出生的三孩家庭中的第三个孩子组成，这些孩子在该省至少生活到20岁（n = 5771）。采用逻辑回归模型来检验最年幼同胞的教育成就与其两个年长同胞教育成就之间的关系，并对一系列混杂因素进行了调整。
如果两个年长同胞都毕业，最年幼同胞高中毕业的几率最大。如果只有一个年长同胞毕业，女性毕业的几率也更高；而这并没有增加男性毕业的几率。同胞出生时间间隔较近时，教育成就之间的关联更强。对于出生间隔较远的同胞，如果这些同胞与最年幼同胞性别相同，那么他们之间的关联更强。
在大家庭中，每位年长同胞的受教育程度与年幼同胞的受教育程度相关；这种关联因年长同胞的出生顺序和性别而异。年长同胞未高中毕业的家庭可能面临诸多挑战。年长同胞未能毕业的孩子可能会受益于额外的支持，以增加他们毕业的可能性。
