Birth order, family size and school failure.
The effect of birth order on educational outcome in the Netherlands is reported for two major social classes, manual and non-manual. The rates of school failure (those who attended schools for the mentally retarded and who failed lower school) were studied in a population of some 200,000 young adult Dutch males born between 1944 and 1946 and whose families of origin had from one to six children. The data used were the records of the Dutch military pre-induction examination. Rates of school failure rose both with increased birth order and with increased family-size, with the exception of one-child families. School failure rates for the first, middle-and last-born were examined for the two social classes, with family size controlled. In general, school-failure rates were significantly related to birth-order position. For each family size and in both social classes, the last-born were at greater risk of school failure than were the first-born.
