Why was Infant Mortality so High in Eastern England in the mid Nineteenth Century?

This paper re-examines the high rates of infant mortality observed in rural areas of eastern England in the early years of civil registration. Infant mortality rates in some rural registration districts in the East Riding of Yorkshire, Cambridgeshire and Norfolk were higher than those in the mill towns of Lancashire. After describing the areas affected, this paper considers three potential explanations: environmental factors, poor-quality child care associated with the employment of women in agriculture, and the possibility that the high rates were the artefactual consequence of migrant women workers bringing their children to these areas.
