While there is a longitudinal literature that considers the impact of poor
socio-economic circumstances upon health, the more specific impact of poor
housing upon health is much less frequently studied longitudinally. This pa
per draws on the National Child Development Study to examine the impact upo
n health of poor housing through the life course. The analysis takes the no
vel approach of constructing a composite severity of ill health measure to
act as the dependent variable. Poor housing is operationalised through a ho
using deprivation index calculated for each sweep of the NCDS. The index of
multiple housing deprivation goes beyond traditional concerns with the qua
lity and amenity of a dwelling to incorporate key subjective factors such a
s satisfaction with dwelling or residential area: these subjective factors
play a particularly important role in the index. The key result is that, ev
en when other relevant factors are allowed for, the NCDS data suggest that
experience of both current and past poor housing is significantly associate
d with greater likelihood of ill health. Moreover, for those who are living
in non-deprived housing conditions in adulthood, ill health is more likely
among those who experienced housing deprivation in earlier life than among
those who did not. Thus, history matters. The analysis also highlights the
increasing inadequacy of conventional measures of housing deprivation.
