The housing conditions of children in the National Child Development Study were related to their health and their height at the age of 16. Although children in crowded homes missed more school for medical reasons, the only illness they reported more often than children in better conditions was bronchitis. Those with inadequate amenities did not miss more school, although they also reported more bronchitis, as well as bilious attacks. Children in council houses were shorter than those in owner-occupied homes, but the only difference in height related to the conditions of the home was that crowded boys were slightly shorter than those who were not crowded. There was therefore little evidence of an association between poor housing and either ill-health or retarded growth among Britain's 16-year-olds in the 1970s, and this was still the case for children who had spent longer periods of their childhood in unsatisfactory housing.
