Family size and ordinal position: correlates of academic success.

The National Survey of 1960 Graduates, which included every woman and every other man who graduated from British universities in 1960, provided a unique opportunity to further our knowledge of the correlates of academic success measured in terms of the gaining of a university degree. A relatively large family appeared to be no impediment to the educational achievements of middle-class children, but for those with less privileged home circumstances a small family was an essential ingredient for success. First-born children were over-represented among this sample, though only children were not particularly favoured. In general, the likelihood of graduation appeared to decrease with each later position in the birth order.
