Notes. Map of treatment status for children according to number of parents treated by the 1972 raising of the school leaving age reform. Parents have to be born within ±3 years of 1 September 1957 to be eligible for a treatment status. Rows indicate mothers’ status, columns indicate fathers’ status. Figures in columns labelled (b) represent total number of children in the cell. The shaded cells indicate children included in the sample (i.e. those with one or both parents born within ±3 years of 1 September 1957); the figures in columns labelled (a) represent the number of the child’s parents who are treated. The lower panel of the Table shows the breakdown of parental treatment status for the children included in the sample.
