Alice Reid is Professor of Demography at the University of Cambridge, and Co-Director of the Cambridge Group for the History of Population and Social Structure (Campop). Much of her work has focussed on the demography of the British Isles in the late nineteenth and early twentieth centuries and the way that different social-economic influences interact to produce geographic and temporal patterns in demographic outcomes. She also has a strong interest in the influences on the collection of historical population data, particularly causes of death, and the importance of such influences for the interpretation of data and results.
