Why do people read into the headlines just what isn't there?
The headline is based on this:
Take a cohort of 16 year olds.
Count how many are still living with both natural parents. Answer 60%.
Of that 60%, how many parents are married to one another 97%.
So - 100 16 year olds
60 living with both natural parents
58 living with married parents
2 living with unmarried parents.
Those statistics are very compelling in themselves, but they don't tell us anything about the other 40% of 16 year olds. Nor do they tell us if parents where unmarried at birth, nor do they tell us about happiness. The actual headline doesn't tell us the proportion of parents who married at anytime in the preceeding 16 years.
What you can infer from the headline is that married relationships, with children, are more likely to subsist.
You have to look at other statistics to develop any understanding of family dynamics.
What I would be interested in is the parental situation of young people who are 'known to the police', broken down into SEC levels.
