Dr Garrett is a historical demographer working on the demography of nineteenth- and early-twentieth-century Britain. Research: Nineteenth and early twentieth century demography of the British Isles, particularly fertility behaviour and mortality decline, with a growing interest in the impact of migration flows on demographic rates. I have worked in close collaboration with members of the Cambridge Group for the History of Population and Social Structure and the History Faculty over many years, considering the demography of Victorian Scotland, with Alice Reid and Ros Davies, the demography of Edwardian England and Wales with Kevin Schurer, Alice Reid, Richard Wall and Simon Szreter, and exploring the factors underlying infant mortality Belfast during the first decade of the twentieth century with Alice Reid and Simon Szreter. Our work on Scotland was undertaken in collaboration with Prof. Andrew Blaikie, Department of Sociology, University of Aberdeen. I also worked with Dr. Peter Razzell, University of Essex, on an ESRC funded project linking late nineteenth century census material to the vaccination birth and death registers for the town of Ipswich. For a number of years I have been a contributor to the Digitising Scotland project, now based at the University of Edinburgh. Since 2015 I have been working for the University of Essex on the Atlas of Victorian Fertility Project, based at the Cambridge Group My research has involved extensive transcription, cleaning, coding, linkage and analysis of individual level census and civil register material along with other late-nineteenth and early-twentieth century sources.
