The representation of firstborns among 1,293 (650 women, 643 men) university freshmen in Kenya (M age = 20.8 yr., SD = 1.9) was explored. In a situation where university admission is very competitive, it was hypothesized that firstborns would be numerically more represented than later borns. The results indicated (a) an overall preponderance of the firstborns (20%), (b) only children and lastborns were the least represented groups at 1 and 5%, respectively, and (c) firstborns tended to come from relatively smaller families than the later borns. The findings were discussed in relation to previous studies, family size, and implications for future research in a subsistence society.
在肯尼亚，研究了 1293 名（650 名女性，643 名男性）大学新生中头胎的代表性。在大学入学竞争非常激烈的情况下，假设头胎的数量会比后胎多。结果表明：（a）总体上头胎（20%）占优势；（b）独生子和最小的孩子分别是最少的群体，占 1%和 5%；（c）头胎往往来自相对较小的家庭，而不是后胎。研究结果与之前的研究、家庭规模以及对生存社会未来研究的意义进行了讨论。
