(...) By examining data from the Millennium Cohort Study, a sample of children born in the UK in the early 2000s, the institute shows that children born out of wedlock are behind in cognitive development at three, five and seven-years-old but this is because "cohabiting parents tend to have lower educational qualifications than married parents". The same pattern is observed with "socio-emotional" development.
