The tables below show the distribution of the study subjects between the different family types in 1991, broken down according to family size in 1981.
Table 1: Lone parents 1981, by number of children aged 0-6 in 1981 and family type in 1991. Row percentages.
The row percentages show that the proportion of lone parents in 1981 who are still lone parents in 1991 does increase with increasing family size. It is possible that some of these lone parents did in fact have partners during the follow-up period and lost them again, but because we only have data on their status at each end of follow-up, we cannot determine where this is the case.
Now let's look at differences between the sexes:
Table 2: As table 1, males only.
Table 3: As table 1, females only.
The main difference here is in the overall distribution of family types at 1991 for males compared to females. Lone fathers in 1981 appear more likely to be married by 1991 than lone mothers do, while lone mothers are much more likely to remain as lone parents than lone fathers are. It is difficult to draw any conclusions about the effect of larger families here because the numbers get quite small.
Finally, let's look at age differences:
Table 5: As table 1, age >= 30 only.
Here we can see that the older age group is less likely to get married and more likely to remain a lone parent than the younger age group. Again, the sm all numbers make it difficult to draw any conclusions about the effect of larger families.
